Image viewers belong to a software category where the quantity and quality of free programs makes it difficult to select just one product as a top pick. So, personal convenience will unavoidably appear as the ultimate factor for this review of free applications. And there's also the question of what exactly we mean by an "image viewer", as the name may sound a bit too restrictive.

Digital photography has become so widely available that most pictures these days will linger in a memory drive and never be printed, because we can see them on screens. As a consequence, hundreds of tools are developed for the task, ranging from the ones that offer just the most basic handling to others with loads of features nobody will ever use. However, nowadays' average users are likely to demand some additional capabilities apart from the simple viewing and browsing functions.

Thus, many imaging applications overlap categories and we have a perfect example in photo organizers, where a viewer is obviously needed to manage albums and the like. Therefore, the differences for this review should be based mainly on the aspects of loading speed, zooming capabilities, batch processing options and other operations not directly related to image editing, tagging or organizing, although this is a definite advantage in some cases like the current Top Pick.

JPG is the most widely used format today because of its quality/size ratio and is supported by every viewer I know of. Though it is quite old and others seem to do the job much better, it has managed to prevail overwhelmingly, both online and in digicams. But there's a steadily increasing amount of people who shoot RAW in their quest for better image quality. Pity that most camera manufacturers use their proprietary RAW formats, of course not supported by the others. Then, after being processed, those files are usually saved as TIF or other lossless formats, including Adobe DNG, Photoshop PSD, etc. Therefore, compatibility is a point which can't be overlooked, as those people will need to view and probably convert a variety of files that our ideal program should handle without having to open an external editor or the specific software bundled with the camera.

Perhaps the most important feature anyone could require from a viewer is that it should be reasonably fast when loading and displaying images. In my opinion, any program that needs over 1 second to display JPGs like the ones produced by an average modern camera or smartphone is not even worth the download. Note that file size (in bytes) as well as image dimensions (in pixels) all have an influence on speed, and hardware is another important factor. Obviously, the better your machine (especially the graphics card, rather than the processor), the better the performance and loading times.

Some of these programs support video viewing, either by using their own player or your system's default player. The subject goes beyond the scope of this review, but I'll say you must have the proper codecs for the various video formats installed on your computer and this is somewhat tricky to get done because you'll have to download and set up additional plug-ins, codec packs or even a separate application sometimes. Full HD and certain video formats usually require a lot of processing power to be displayed. The articles Understanding Codecs and Best Free Media Player are good readings to learn more.


Zoner Software are the developers of one of the commercial programs I've been using for a long time to view and manage my huge picture collection, so when I saw they released Zoner Photo Studio Free, I guessed it was going to qualify high enough for its inclusion here. It certainly did, but who knew it would climb up to be the Top Pick! The interface looks very professional, although it could even seem a bit daunting and bloated for certain users with all those menus, tabs and icons, but it's very intuitive and tooltips show up for everything. Comprehensive help and links to video tutorials are provided as well.

Four main tabs are displayed at the top right, each one addressing a task: import (to acquire pictures from connected devices), a manager (a thumbnail view with a folder tree and general information), a viewer and an editor, which is quite stripped down compared to the paid version but still very functional. ZPSF generates thumbnails in a blink, much faster than any other I've seen, and general speed is outstanding, especially if you have hardware acceleration enabled in the preferences. The zoom system now includes a one-click magnification similar to the one in FastStone (see below). There's a powerful search with many filters and a lot of options for customization of menus and shortcuts. The functions are too many to be mentioned and generally very useful, but a couple of them alone make it worth using the program: one is the ability to temporarily rotate pics and the other allows to straighten them by drawing a line. You can also compare up to four images with synchronized panning and zooming, even if they are contained in different folders. The editor has a variety of tools like a handy clone stamp, a funny morph mesh and great effects that can be applied on selected areas. You can also make automatic backups of your photos, organize them into albums or catalogs, geotag them by dragging and dropping them onto a map, build calendars, stitch panoramas and a lot of other things. Moreover, it reads many formats, including RAW, and writes to the ten most commonly used. It supports video from within the program, 64-bit architecture and multi-core optimization.

On the downside, ZPSF takes over 350MB on your disk, an awful lot more than any of the competitors in this review, and it needs 1GB RAM. Color management isn't supported either. Advanced batch processing options are only available in the paid version, except for renaming, though most individual operations can be carried out on more than one file at a time by selecting a number of them in the manager, opening the specific dialog and then clicking 'Apply to all'. You also need to provide a mail account to activate the program. The download link on Zoner's site points to Cnet, which can be objectionable for their download policy and their wrapped installers, but it can be downloaded from other sites like Softpedia or Majorgeeks. Although Photo Studio might be a little overpowering for the needs of average users, it's undoubtedly an excellent program with lots of possibilities for those willing to take advantage of its many features.

XnView Tumbnail ViewXnView used to be my Top Pick till the release of Zoner Photo Studio Free and I would really keep it as such if there could be two of them. It's probably the most versatile of all viewers because it can read 500 types of graphic files (some of them may require plug-ins) and convert any of these to more than 50 formats. It displays images very quickly and these may be viewed in full screen, as slideshows or as thumbnails. It's quite capable at processing images, too; you can rotate, crop, resize, adjust brightness and color, apply filters or effects, create a web page and much more. Most of these operations can also be carried out as a batch, which is ideal for converting or processing multiple images with custom adjustments.

The thumbnail window can fit your preferences with several layouts and sizes; this is especially useful when displaying panoramic images in preview mode (see screenshot). It offers nearly instantaneous hotkey and wheel zooming, and dragging the image around at any zoom level is perfectly smooth. It also allows having several images open at the same time and even running multiple instances of the program if you like to browse in different windows. It supports drag and drop, color management (with slower loading times), geotagging, lots of plug-ins, is available in 45+ languages and has full cross-platform support, including Mac and Linux (unlike its competitors reviewed here). A heavyweight champion.

IrfanView Thumbnail ModuleOne of the best choices is the classic IrfanView. This is a first-class product, but one for which I have mixed feelings. It's an amazingly capable application and quite fast at displaying images. It offers plenty of functions for editing, converting, batch processing, slideshow exporting, panorama stitching, etc. and supports almost any graphics plug-in (including one for color management). Some of the features (its resizing algorithms, for instance) are outstanding and even rank above a big fish like Photoshop. It's a small download and it takes a mere 2MB on disk.

But, although many users love it, it just doesn't work the way I'd like it to. It's quite simplistic, but not really intuitive and the interface has been almost the same since early versions. As a personal "inconvenience" I'll say wheel zooming requires a press of the Ctrl key, RAW support needs several different downloads and installs for plug-ins or dll's, and I don't see the point in having a separate module for thumbnails. This, however, may be exactly what others prefer and the same applies to the interface, which looks a bit too outdated to me. But, obviously, Irfan is a real winner. (The first download link on Irfan's site points to Cnet, which can be objectionable for its download policy and the unwanted additions it installs sometimes. Many alternatives can be found on the same page.)

FastStone Thumbnail and Preview window FastStone Image Viewer is another excellent choice. There are various reasons to choose this, but perhaps the main one is its superb interface in full screen mode, with different pop-up panels appearing when the mouse pointer reaches any side of the screen and disappearing when it's withdrawn. You can easily access nearly every function of the program from this window with no other element disturbing you until you decide it with just a mouse move, including a very handy thumbnail slider to browse your images. Even the smallest menus or panels in any of the modes are clear and well designed, and there are several skins available.

Aside from the usual wheel zooming, the zoom system has a very clever feature: it magnifies to a custom preset level with just one click, lets you pan through the image while holding the button and returns to full view when it is released, something really useful to check out sharpness or detail in a photo. Average files are displayed quickly and their thumbnails are generated promptly. But it's slower showing bigger files (>20MB, depending on the format and resolution) and others perform much better in this field, though that won't be an issue for most users. It may be a good idea to disable the preview pane in the thumbnail window as a way to speed things up. There's also an option to use color management, but it increases loading time. Another outstanding plus is the batch processing options, quite extensive and really easy to set up and run. A few useful editing features have been added in version 4.3, including curves, levels, lighting, unsharp mask, clone and heal. It also supports all major graphic formats and popular digital camera RAW formats as well, and offers an excellent cropping module, great slideshow capabilities and GPS location with Google Earth. Much to like here. (The first download link on FastStone's official site goes to Cnet, which sometimes uses wrapped installers. Some alternatives can be found by clicking on any of the other links on the same page.)

WildBit Thumbnail View I can recommend another program, after most of my initial objections were overcome by the evidence and the author, who also showed a very positive response to my feedback. This special mention goes to WildBit Viewer, an outstanding application that can rival the ones reviewed above in many aspects. In spite of some minor concerns about speed, the program is highly manageable and functional enough to earn the respect of many users.

Apart from the usual features you'd expect, it offers aspect ratio information, small-increment wheel zooming, a very intuitive image editor with a full array of editing tools, a superpowerful search function that can track any metadata or EXIF information, an excellent geotagging tool to embed geographical co-ordinates in the files, and the most comprehensive help you can imagine. There's also a function for side-by-side image comparison with difference calculations, and a highly customizable slideshow mode. It supports over 70 formats (including some videos, from which frames can be extracted in multipage view) and runs on Windows XP through W8. From version 6 on, it includes full Unicode support. WildBit Viewer is a very competent alternative.

I've tested quite a few other applications (too many to be mentioned), but none of them made it to the top. That includes all of those suggested by readers —though I always have some of them pending—. When this was the case, I usually replied with a post in the comments section with my reasons. Maybe your favorite program is among them, but please feel free to submit any product you think might deserve a try after having tried it yourself. There are some decent ones and even Windows' built-in viewer performs acceptably when browsing through average images, although it's very limited. I haven't tried Windows 8 yet, but one would expect some improvement over the old XP and the successive OS's regarding this, because it was disappointing to find out neither Vista nor Windows 7 were significantly better for the task so many years later. This article is going to be lengthy but, anyway, it wouldn't be fair to end the review without mentioning some other freebies that offer quite remarkable features. (Thanks to everyone who let me know about them.)
Users who just want a simple replacement for the default Windows photo viewer have a very good alternative with ACDSee Free, which was first released in 2012. Its commercial sibling has long been one of the highly regarded applications in this area and the free version is on par with it in terms of speed, which is impressive. Almost no other program can display pictures as quickly as ACDSee, no matter the image size. For this alone it deserves a place in our review. The interface is simple and clean, and its default gray color is appropriate for a correct viewing experience. The mouse wheel can be used for zooming by pressing the Ctrl key, though its primary function is to select the previous or next image in a folder. A double click displays a full screen view and a few keyboard shortcuts are available for navigation. It supports 11 common formats —including animated GIF, but not RAW or PSD—, and can convert to 8 of them using the 'save as' command. Other functions include rotate, copy, set as wallpaper and a very nice group of printing options. And that's just about it!
Speed is the strongest point in its favor but if it hadn't been for that, probably ACDSee Free wouldn't be listed here because there are no other special features to talk about. It's just a sequential viewer like many others and it relies on Windows explorer to access folders and images. I miss some more customization or any kind of sorting options. For my review I usually test the programs on different systems, machines and screens. In this case I must point out the unsatisfactory quality of ACDSF's image rendition for JPGs on all tested environments. The problem isn't evident at closer zoom levels, but when fitting the whole image to the program window it appears a bit blurry, but the TIF and PNG versions for the same JPG files look nicer and crisper. A personal inconvenience is that the Esc key always closes the program. On another note, the installation occupies nearly 30MB on disk, which is a remarkably high amount for such an apparently simple program. Nevertheless, all these drawbacks could be considered as minor. I know simplicity and good speed are what many users really want for their needs, and ACDSee Free is a champion at both.
(ACDSee Free seems to have been discontinued, as it isn't listed on the official website anymore, but it can still be found at some download sites like the one in the link above. Anyway, I guess I'll have to remove it from Gizmo's Freeware in the near future.)
Simplicity and speed are also key features in a very nice program called Nexus Image. This one was suggested by one of our readers (choifamilyipad) and it has turned out to be probably the most appealing of all the "simple" viewers to me because of its outstanding image quality and beautiful interface. You can change its opacity and color, and a vertical thumbnail strip on the right makes browsing easier than in most other simple apps, where a linear previous/next file navigation must be followed. Folders are quickly accessed by double clicking the viewing window, selecting one from the tree and opening an image. Then you can use the functions either by right clicking and selecting them from the context menu or by means of conventional shortcuts, although mouse wheel zooming requires pressing Ctrl. Captions can be added to pictures, it can show EXIF information, supports common formats (not RAW, but does PSD and animated GIF), is available in many languages, has a light footprint on your system and is fully portable, with just a 2MB download.
On the downside, being so simple means there aren't many features to talk about and I miss some of them in particular, namely some kind of sorting options for the thumbnails, basic cropping, and permanent rotation applied to pics, as it is just temporary in this software. Again, if you're used to pressing Escape to close a fullscreen view of an image in other viewers, then you'll find it a personal annoyance in Nexus, because doing so here closes the program with no prompt and you just can't help pushing the damn key... Well, anyway, that's something you can live with, I guess. And this program is worth the trouble.
Honeyview, suggested by our reader Pliskin, is also one of those simple viewers sparing in features and focused on the basic viewing experience. It has a pleasant interface and a small set of intuitive controls for navigation. Most functions are accessed via right-click menu or keyboard shortcuts, and you can configure up to seven hotkeys to your liking. There are a few basic sorting options available and a slideshow mode. You will love its great speed even with big files and formats such as PSD or LZW-compressed TIF, which the majority of viewing programs take longer to open. The image quality is also wonderful and RAW files are beautifully rendered if you choose not to display the embedded JPG, although  this method is obviously slower. What is not slow at all is the rendering of images using the ICC color profile they may have attached; this is a remarkable aspect where nearly all the competitors are extremely weak, even the top ranking ones. Quite a lot of settings can be tweaked to fit your preferences, including background colors, mouse buttons' behavior, etc. The wheel can zoom in 10 or 1 percent steps. It supports 15 common file types (including animated GIF, which you can see frame by frame) as well as the main RAW formats, and is able to view images directly from compressed files without extracting them. It works on Win XP through W8 (32- and 64-bit) and a portable version is available.
The drawbacks are very few, assuming that the program is sparing in features. There's a thumbnail strip that shows a small preview but it's inside a menu and the design is awkward, as it won't let you click on a thumb to open the image. There are just two editing functions: rotate and resize, both sharing the same panel under the 'Convert' heading. The output conversion can only be saved to JPG or PNG. There's no cropping whatsoever nor a desirable TIF output that would be really handy to save the program's nice rendition of RAW files. When you are browsing, any eventual rotation is just temporary, but if you use the rotation commands, whatever pics you display after that will appear rotated, a peculiar all-or-nothing approach. Anyway, you can always set the preferences to autorotate based on EXIF info.
Nomacs is a very interesting open source program that was suggested by our fellow editor Panzer. It looks nice and simple and offers the features I like to have in a viewer, such as a built-in folder tree, a thumbnail preview panel, a thumbnail strip, a few sorting options, a histogram, EXIF information, excellent image quality and is reasonably fast. It supports quite a lot of file formats, including RAW and PSD. RAW images can be displayed either by showing the usual JPG embedded in the file or by rendering the photo with the program's own algorithms. A few basic adjustment options are also available, like rotation, cropping, resizing, and correcting brightness, contrast, saturation, exposure, etc. There's a slideshow player available, too. But Nomacs is really special because of a few other things that are really uncommon for programs in this category. For example, it can change the opacity of the interface, show images in a frameless view on your desktop, rotate RAW files permanently, build a mosaic based on a target image composed by any number of other images, or pause animated GIF files and save their individual frames. These are all outstanding features, but something I had never seen before is that multiple instances of the program can be connected to work together on the same computer or even synchronize them across a LAN to perform several specific functions on different machines at the same time. Moreover, it has 64-bit versions and can run on Windows, Mac OS and Linux.
There are a few inconveniences, though. Getting the more advanced features to work can be difficult at first and some general functions take some time to get used to when you come from other viewers. Occasionally, the program isn't very good at rendering RAW files with its own algorithms, especially when some highlights in the picture are already blown out, as an unpleasant magenta color appears on account of the lost information (probably due to an inadequate RAW saturation point). Wheel zoom works in totally random increments, so it's almost impossible to get the same amount of magnification twice and you can't zoom to a desired exact level with it. There's an option for 100% view but the program allows no other custom zoom levels. The thumbnail panel always shows square thumbnails, irrespective of their content, so there's always a hidden part in them unless your pictures are square themselves. Without these drawbacks Nomacs could probably be mentioned along with the top products in this category.
During some past years of writing for Gizmo's Freeware I was reluctant to include Picasa here because I (still) think the main program isn't actually a good viewer. Many times I was asked why and I gave a lot of reasons. But then one day (thanks to our reader Kurt B) I discovered Picasa contains a separate picture viewer that can be used as an independent program. And it's quite good, so I had to change my mind. It's nice, fast and simple, and in this respect it could be considered as an ideal replacement for the default Windows' photo viewer. It doesn't provide a lot of features by itself, but it can be combined with the main sibling app to obtain good functionality when it comes to editing and the rest of the many features that it offers. It reads a lot of formats (including RAW and PSD), wheel zooming and panning are smooth and its image quality is excellent. The rendition of RAW files is one of the best I've seen, although many times one would prefer to be able to check out the embedded JPG for an idea of the behavior of the camera.
There are just a couple of "major" cons I can find with Picasa. One is the fact that the image is always smoothed when viewed at close zoom levels exceeding 100% and the individual pixels aren't shown: this isn't good if you want to appreciate the real quality of an image when inspecting it for artifacts such as the ones that often appear in JPG pics. The other inconvenience is that Picasa doesn't make it really clear you can use this viewer separately, and subsequently you could think that you'd have to make do with the one in the main program, which isn't half as good. I apologize because that's exactly what happened to me for quite a long time.
One of our anonymous users suggested cam2pc and, after giving it a try, it has proved to be an excellent program in many aspects. As the name suggests, cam2pc provides a handy way to download pictures and videos from your digicam to your drives, allowing you to use lots of options for renaming, saving, etc., and has specific support for the widely used Canon EOS cameras (separate download). The interface is intuitive and easy to use, with a folder and thumbnail view that recalls FastStone. As with this, I recommend to turn the preview panel off, though thumbnail generation is really fast. Actually, speed is outstanding in almost every aspect of this app. The feature that impressed me most was its ability to quickly display LZW-compressed TIFs, something unusual in its competitors, although these perform better with Photoshop PSDs.
The only reason why I don't include cam2pc along with the top programs is that the freeware version lacks quite a lot of features that can only be found in its commercial sibling and which the others offer for free. But I guess most users could perfectly do without those.
Imagine is a very fast viewer vaguely resembling Irfan in its simplistic interface, though the number of features is far more reduced. Wheel zooming also needs pressing the Ctrl key. Several instances of the program can be open at the same time, it lets you customize various mouse modes with different configurations and select any of them instantaneously to fit your workflow, allows frame extraction from animations, reads inside zip, rar and 7z archives, has multilanguage support and is portable.
On the downside, it's quite limited in other areas; for instance, the editing and batch processing options. No RAW or video formats are supported. Sometimes a few Photoshop PSD files can't be read and an 'out of memory' message appears when trying to open them, irrespective of their size and my lots of free RAM and processing power. But the app is an AWSOME performer with the PSDs that load properly and displays them nearly instantaneously, once the thumbnail has been generated. This is something I haven't seen in any other free viewer, and only one or two commercial programs can boast similar results!
Picture Information Extractor Free (PIE) comes to this article after Panzer's suggestion and because it has nearly everything I think a viewer must have. Anyway, the developers insist mainly on the ability to visualize all the metadata embedded in pictures, which is undoubtedly another way of viewing them. EXIF, IPTC, XMP, keywords and other data are conveniently shown on a pane to the right of the screen when a file is selected. The main interface also displays a folder tree with a preview pane and the files can be sorted in various types of lists or thumbnails. The features include wheel zooming in fullscreen view, custom thumbnail size, powerful search, excellent import options, wonderful renaming capabilities, it reads RAW and PSD formats, deletes RAW+JPG files with one click, supports color management and has good image quality. As an outstanding plus, PIE is one of the very few programs that can rotate RAW files permanently and for some users this feature alone would make it worth the installation.
On the other side, this free version of PIE cannot save any changes to the metadata, which is the only cut compared to the commercial one, but quite significant. There are also a couple of flaws in important areas such as speed or zoom. No problem when you're surfing through average JPGs, TIFs, etc., but it takes some time to even change directories and access a folder full of big RAWs, and then another while to display each file in full screen. The zoom can't reach pixel level and, along with pan, it's a bit sloppy. Moreover, the wheel turn for zooming in or out works in the opposite way to the rest of viewers I've tried so far. I miss animated GIF support as well. But many users won't even notice these drawbacks.


Pictomio is a good representative of the recent trends in this category, which pay greater attention to "fancy" interfaces and presentations to improve user experience. The main drawback with this is the usually high resource consumption and graphics card requirements, and the program is no exception, as it uses DirectX hardware acceleration. I'd say it is mainly geared to organizing, with a great number of options for tagging, metadata editing, rating and grouping, but it performs very well as a viewer, too. It's really fast once the thumbnail indexing has finished and displays an image preview instantly, and you can zoom in and out to any level. It supports some video formats as well. The interface is really nice and its many tabs show a lot of information.
Pictomio, however, is not intended to edit and there are no options for this other than lossless rotation. There's no support for RAW, PSD or animated GIF formats either. Moreover, indexing should be faster and it fails to generate a thumbnail for some really big files, but the picture is displayed perfectly if you click on its blank rectangle.
Although their names look nearly identical, Imagina has nothing to do with Imagine, reviewed above. Actually, that's where similarities end. This application ('a next-generation image viewer and editing tool', the developers claim) is a perfect example of the new concepts based around 3-D technology, but much lighter on resources than Pictomio and others of this kind. Browsing speed isn't as fast either, even compared to "normal" viewers, and this is especially noticeable with bigger files. For instance, when opening my EOS 7D's 18-megapixel JPGs the program clearly stays behind the top performers, though this should mean no issue for average users, as their files will be half that size or less, typically.
There may be some things I really miss (more customization for certain basic aspects, a built-in folder tree, support for PSDs, more straightforward management of some files like TIFF, etc.) and many other reasons why my workflow as a photographer won't (yet) fit what Imagina proposes at this seemingly early stage in its development. But photo pros are only a few among the vast lot of digicam users who just shoot JPG. And these will love it! I do love it too, believe it or not. Its absolutely outstanding features have captivated me. User experience is excellent and no other viewer I've seen shows that image quality or that zoom and pan smoothness. Both 2-D and 3-D graphics are amazing and even videos can be watched in this environment (with zooming and panning!). It offers state-of-the-art RAW support by using David Coffin's DCRAW along with its own algorithms, top quality editing functions, real color management and some useful tools, like the 'straighten picture along a line' that many users have been craving for. So many good things make it at least a must-try. (Requires .NET 3.0 or higher)
After some debate in the comments section I've decided to mention FastPictureViewer, but just because of one single feature. This claims to be (and probably is) the fastest viewer ever, especially indicated for quick browsing and culling. Like Pictomio, it uses hardware to speed things up and requires a lot of system resources and graphic capabilities. It has a nice interface as well. Anyway, the program offers very few functions once the initial trial period expires and actually becomes limited to viewing JPGs and not much more than screening and tagging. It does support full color space awareness, though, and the unbeatable speed is a very strong argument in its favor.
Finally, one of our site users, Mythril, suggested two programs which work with a very different approach, but with a special focus on speed. These are Vjpeg and Osiva. I just quote Mythril's comments because they are right on spot (original 06/02/09): "Both work by opening images in a borderless window that you can drag around and zoom in/out at will, practically without any lag, and you can open as many images as you want at the same time. Both programs load very quickly, but don't have any features to speak of. Another drawback is that there doesn't even seem to be a way to cycle through images in a directory... Osiva is slightly better in that you can easily drag and drop a bunch of images and have it open all of them for a superquick overview". I'll add they support very few file formats and are a bit awkward to use, but Vpej and Osiva are quite different from what I had seen so far.
Another reader, Bziur, also put forward First Impression, which works in a similar way without an apparent interface, just by using right-click menus and offering pretty much what the name of the program suggests.
This impressive entry in the Wikipedia features a chart comparing a considerable amount of free and commercial image viewers. Most of these products are also given detailed individual entries and include links to their websites.

How do I remove the whitespaces around the image that appears when an image is resized smaller than the original. It seems like when I resize the original image, white square spaces appear around it. Any help would be appreciated. I use XnView. Same was the case with IrfanView too.

You might want to check if the white space around the image is part of the canvas size and/or border. In Irfanview, click Image > Change canvas size, and/or click Image > add border/frame.

George, I'm sorry to say I can't help as I've never had this issue, neither with Xn nor Irfan. After reading your comment I've carried out several resizing conversions (individual and batch) with both programs to see if I could reproduce the problem and I couldn't.

A Google search for this problem reported a few results concerning conversion problems related to aspect ratio, but not with Xn or Irfan. If I uncheck the 'Keep aspect ratio' box and give random numbers or percentages, the image will be distorted but there's no sign of white spaces around it. Sorry.

Could you suggest me a program to view large TIFF pictures, please? (300MB).

If the file is very large most programs take a really long time or they just crash.

[edit by moderator] Suggested program details removed. We can only find this listed as shareware. Please provide a link to a true freeware version if you wish to discuss it here.

I know what you mean, skan. Those long waits for a file to open are really frustrating. But I'm afraid it's not only a good program what you need to cope with those large files.

As I state in the introduction to my article, hardware is an important factor when viewing images. And when the files are bulky I dare say it is the most important one. Ever since I have invested in newer computers with good graphic capabilities those waiting times have been HUGELY reduced. When I started to work with computers and until a few years ago it could take forever to open big PSD or TIF images on affordable machines. And if those files were 16 bits in depth, many times they couldn't even be opened. From 2006 up till last December I had been using a dual-core 2GHz PC running Win XP, with 4GB RAM and a decent 256MB graphics card. An uncompressed 300MB TIF usually took around 6 to 15 seconds to be displayed, depending on app, bit depth, image dimensions and several other factors, but the improvement over my previous systems was really meaningful. At present, my main working computer is a six-core 2,8GHz running Win7 64bit with 6GB RAM and a 1GB graphics card. Now almost any decent program like the ones in my article can open 600MB (yes, six hundred megs) 16-bit TIFFs in less than 2 seconds! I guess this isn't the kind of answer you'd expect from me but if you have to work with large files frequently, you should consider a hardware upgrade, just in case your machine is the problem.

Oh yes, sorry; you wanted a good program to view those big TIFFs. Well, that ACDSee you said you've got was supposed to be good enough, as it's one of the leading payware apps in this category! I understand your disappointment perfectly. I don't know which ACDSee version you have, but if it is the PRO ($240) and it keeps crashing when you try to view big TIFs, you'd sure be doing much better with a $100 graphics card and almost whatever program in my review!

Anyhow, irrespective of your machine, there's another important point that must be taken into account: LZW-compressed TIFs usually take MUCH longer to load than uncompressed ones, even with good hardware. If this is the type you use mostly (I do, just because they take way less disk space), then the best app I can recommend is cam2pc (see article above). Its speed at managing those is unparalleled and it's also very fast with the other formats.

As for the rest of the programs I mention, I've tested them all under different conditions and on many different computers (desktops and laptops). If they appear here it means they offer very good or at least very acceptable performance and will be able to display the files you want with no problems. Any of those in my top 5 is a great alternative to (if not better than) what you've already got. But remember what I've said about hardware!

Whatever app you finally choose, it would be nice if you could please take a couple of minutes to report your experience with it here. Thanks.

Finally I've found a program that can view very large tiff files. It's called FWTools
It can zoom in and out, export it, and make some modifications on it.
And It's free.
Even though It's not supposed to be an image viewer but a map tool, it works very well and really fast.

It opens the image almost instantaneously.
It proves that loading all the image on the memory is not the way to proceed. You just need a program properly writen that only loads what it needs every moment: more detail of some areas if you zoom in, or less detailed view of the whole image.

by marcdarkin on 27. January 2012 - 16:50  (87899)

Thanks for sharing your finding, skan. I'm glad you got what you needed.

I've seen FWTools is a specialized set of open source programs for geographical information systems. Probably not many 'normal' users will need something like that, but it's still good to know it can open those very large TIF files so fast. Here's the link in case somebody is interested:

by skan (not verified) on 13. July 2012 - 12:57  (96134)

Hello again

I've found a similar tool, called Quantum GIS. It has a browser that also opens tiff files.
I think it uses libraries newer than the libraries used by Fwtools

by marcdarkin on 13. July 2012 - 15:32  (96139)

Thanks again for the info, skan!

by skan (not verified) on 27. October 2011 - 12:30  (82229)


I was using a trial version of ACDSee but now has expired.
Anyway it dodn't work for me and is very expensive.

I know that is better to have more memory (I've got 6GB) but I think it's also a matter of how the program works. It's should try to load all the picture on to the memory.

by Nihlathak (not verified) on 27. August 2011 - 6:34  (78424)

Zoner Photo Studio Free can't view animated PNGs and XnView crashes constantly when I use the browser. Anything I can do?

by marcdarkin on 29. August 2011 - 12:02  (78554)

Imagine, reviewed in my article, also supports APNG files.

by marcdarkin on 28. August 2011 - 17:20  (78513)

You can try and open the APNG files in Firefox or Opera to view them.

Does the last free version of FastStone's MaxView qualify as a viewer? I like it because it's light and loads pics quickly when I want to just see one. I used to use Irfanview for this but now maxView is my fav. Here is a link to the last free version-
[wrong link - deleted by moderator]

I'm running this version on Windows 7, 32 bit with no probs.

by marcdarkin on 28. August 2011 - 17:19  (78512)

MaxView is shareware currently. AFAIK, its latest free version was 2.2, and I hate that one because they changed some features I really liked (for instance, some hidden bars and panels). My favourite was v. 2.1 and it dates back to 2007, but it can still be found on some sites if you google for it.

Fast Stone Image Viewer is just as good, with very few significant differences. I even think average users will prefer it over MaxView. Thanks for your comment.

Sorry about the delay to answer and also that your comment was removed from this section. The moderators are strict (they must!) and you have to admit it was a really long piece. I was able to read it just because all the comments that appear here are automatically forwarded to my personal mail.

I'm really sorry it can't be published here, because it must have taken you a long time to write it and with your best intention to help. You raised some really interesting points in it and I totally agree with many of them. Actually, I appreciate your insights a lot and perfectly understand your concerns. I tend to be a bit verbose myself sometimes, but I can't extend an article that I think is already too long, otherwise many of those details you provided would be included too. (I think I'll mention FIV free being such a nagger ;) )

Anyway, if you could summarize your opinions into a shorter piece, we'd be more than happy to have them published here and other people could benefit from your experience.

Thanks a lot for your contribution!

Well, am glad Marc that you read it in the mail :). The comment was duly summarized and published. The comment below by FF, is that comment :).

FS MaxView 2.1 is easy to find, it's version 2.2 you need some time to excaveate. So if 2.1's even better...

And oh yes, I also use FS Capture 5.3, the last free version of their screen capture program, highly recommended since it's fast, whilst the "industry leader" takes 20 times or more of that time to save a rectangular or any other part of the screen.

Thus, FSC 5.3 has become invaluable for me for my web clippings downloading, I only download plain text (excerpts / snippets) and such rectangles, not whole web pages.

I would have bought the lastest version, but see above - from such people, I don't buy anything. (And I'm happy to not having to steal from them in order to get my way nethertheless, up to now = XP as said.)

What's wrong with photoscape ?

by marcdarkin on 29. August 2011 - 12:00  (78553)

After having reviewed its v. 3.5, I'm sorry to say Photoscape does not qualify as a good viewer, or at least not good enough to be included in my article. Being able to do so many other great things, it's a pity it can't pass the test in this category. I still see the same inconveniences I mentioned before (no wheel zoom, maximum zoom 100%, thumbnails can't be resized, few supported formats). I can't live without RAW or PSD formats and this alone is a big drawback, but even people who don't use them could be annoyed by its average speed, slow thumbnail generation, clumsy zooming and panning, only four icons to perform simple functions, no sorting of any kind, and absence of quick file information (size, etc) unless you hover with the mouse, to say just a few things. And yes, there's a RAW converter but you have to use Windows Explorer to load the files into the app. It's just like having no RAW support at all if you can't preview the files you want to convert.

(Contrary to what I said in my previous comment, Chrome isn't included in the installation pack.)

Photoscape is a great program in many aspects, and photo edition could be one of them. But when it comes to image viewing you have to admit it's just a contender that can't play against the best in this class.

by marcdarkin on 29. July 2011 - 12:32  (76448)

I reviewed Photoscape v.3 back in june 2008. Yes, I know it's been a while and probably the current v.3.5 is a lot better. Actually, it looked very promising then. I have quite a long list of pending reviews that includes many other programs, but I just don't have time at the moment. It's kind of an all-in-one suite and not just a viewer with additional features, something which made me a bit reluctant at that time, but having ZonerPs as my top pick today, I can't use that as a negative point anymore. The following are some excerpts of my own comments published here in 2008:

"The interface is well designed and offers a lot of nice features for those who like to have everything at hand: a powerful editor, animated GIF builder, web page maker with many templates, a function for combining photos, etc. But I can't recommend it in my top list of viewers because there's no quick zooming and maximum zoom level is just 100%. Besides, thumbnails can't be resized to fit the user's needs and it supports only a few formats, not including Photoshop PSD. These reasons alone make PhotoScape almost unusable for someone like me, but it can indeed satisfy many others with its nice extras."

Though maybe not at the top, I guess Photoscape could qualify to be mentioned in my article but it will have to wait. I'm starting my vacation tomorrow and I'll be away for more than two weeks, but I'll take a look as soon as I can. I suppose you just want to know why it's not included here, but it appears in some other reviews on this site:

By the way, the installation pack comes bundled with Google Chrome and seemingly there's no easy way to opt out. This is a real concern.

by vickyrajai (not verified) on 23. July 2011 - 10:07  (76093)

very good.

by Sigit (not verified) on 20. July 2011 - 2:21  (75868)

I prefer FastStone Image Viewer. I've been using it for years and it never disappoint me.

I've installed the software that rank above it but nothing satisfy me. IrfanView: its interface is way too simple. XnView: needs addon to add function that FastStone already built in. Zoner Photo Studio: big file download.

So, I think FastStone is the best.

by qasimmgm (not verified) on 17. November 2011 - 17:02  (83437)

Sigit, thank you very much, I was writing my comment and found yours, it is exactly what I want to say, I will not add anything

by KTlin (not verified) on 19. July 2011 - 22:10  (75861)

I forgot to mention how helpful this article was. Very good review of each software. Thanks a lot!

by KTlin (not verified) on 19. July 2011 - 22:06  (75859)

FastStone Image Viewer is absolutely GREAT :)
It is exactly what I needed. Way better than ACDSee, IrfanView, XnView, Nikon ViewNX, WildBit Viewer, Picasa, Zoner Photo Studio Free. I tried all of these but at the end I found FastTone Image Viewer to be perfect for me.

Highly recommended!!!

by qasimmgm (not verified) on 17. November 2011 - 17:05  (83438)

yes, indeed

by deetailed on 14. June 2011 - 12:03  (73784)

On the review for Imagine, you mention "it doesn't keep a database, so the thumbnails have to be generated again every time you visit a folder". I'm using version 1.0.7 right now and it seems that feature has been added. Currently, I prefer it to all viewers I have used (ACDSee, XnViewer, IrfanView, CDisplay and CDisplayEx). Very fast and light on resources (less than 1MB after I deleted language packs that I don't use), support opening zip, rar and 7z, and available in portable version. I haven't tried its editing features, but even if they're no good it still makes a nice viewer.

by Panzer (not verified) on 19. October 2011 - 8:03  (81689)

Cdisplay and CdisplayEx are optimized for wathching comics. Btw, Imagine 1.08 is already out.
