There are many different audio and video formats out there, and most devices (such as iPhone, iPad, Android phones, etc.) and programs (such as Windows Media Player) are only compatible with a few specific formats. An AVI or WMV movie will not play on an iPhone, for example, without being converted into an MP4 file first.

There are quite a few programs that will do this for free, with more popping up all the time.  They tend to fall into a few general categories:

  • If you want to convert audio & video easily, with a polished interface, support for virtually all file types including online video websites, and an integrated precision video editor, I recommend that you try our Top Pick.
  • If you want to convert without fiddling with any settings, using as few clicks as possible, try our Device-Specific Picks, which are especially suited to quickly setting up a conversion for a portable device.
  • If you want to have control over basic settings (such as framerate, frame size, and bitrate), yet still experience a quick, low-frustration conversion where most of the guesswork is done for you and you don't need to be an expert to get the job done, try our General Converter Picks.  Our Top Pick is in this category.
  • If you want complete control over every detail of your conversion task, where you have the ability to fine-tune your output using settings that most of us, including the Reviewer, don't even understand, then you may be interested in looking at our Custom-Oriented Picks.
  • If you only want to convert audio files, yet you want more audio-specific functionality, then try our Audio-Only Picks.
  • And lastly, if you're looking to convert a wide range of file types, from video to audio to documents to images, and you want to do it on the fly, you might want to check out an Online Conversion Website service.  There are sometimes file-size restrictions with these services, but they offer the convenience of being accessible from any browser.

While some are better than others overall, which one is best for you will depend on what sort of program you need.

Device-Specific Picks

Pazera Free Audio Video Pack Pazera Converter Screenshot (former Pazera Video Converters Suite) is really a package of several separate converters with a common launcher. Each converter is powerful, with several presets for device, custom tweaking/profiles, multiple-file support, all in a simple text-based interface. If you don't mind the launcher, you could effectively use it as a hybrid converter.



Miro Image

For even easier device conversion, there is Miro Video Converter. With just a dozen device presets and support for only one file at a time, it may not be the best choice for power users. However, its simple interface is 'newbie-proof', and conversion quality is on a par with other programs.




Also recommended:

  • Handbrake:  A long-time favorite of mine, when I need to convert from just about any format to a nice, no-nonsense iPod/iPhone compatible video (encoded in H.264).  It has a queue, and supports multiple Apple presets including Apple TV.
  • WinX Video Converter: More up-to-date than iWisoft. Support converting videos to 100+ devices including newest iPhone 6/Plus, S5, HTC, PS4 with many preset profiles. Adjustable video audio parameters. Clean and simple. Please note though on the top there's YouTube URL entry, it is just an upgrading recommendation which can be skipped easily. This freeware doesn't support converting YouTube videos.

General Converter Picks

Freemake Video Converter is the new Top Pick.  The interface is about as polished as it gets, and the code behind the interface is stable, flexible, and powerful.  Using Freemake is a linear, seamless experience with no frustration.

What I do find frustrating, however, is that the developer has now added OpenCandy to their installer.  For more information about this bundled software, I recommend you read this article.  Please see the last paragraph of this review for information on how you can opt out of this.

Now, back to the awesome stuff.  With Freemake, you can convert most any format of video or audio with this handy piece of freeware, along with DVD's, photos, and even web embedded media from sites like YouTube, Google, and Vimeo.  There are lots of presets and quite a few options, giving the software best-in-class capabilities.  The visual cues are easy to follow, pretty much guiding you from start to finish on any conversion task and providing a more user-friendly experience than most other software.

This software can make use of DXVA and CUDA (two methods of hardware accelerated encoding) to boost speeds.  I was only able to use DXVA on my test computer, so you may get faster encodes with your machine.  On my laptop, I had an NVidia card, and Freemake actually displayed a message recommending that I update my video card drivers to make use of CUDA acceleration.  Freemake took 39 minutes to produce its output using an Auto Bitrate setting, with a two-pass encode.  It took under 15 minutes to do a one-pass encode.  Handbrake took 33 minutes using a Constant Quality RF:20 setting.  The quality of all three test encodes was excellent, with no apparent difference from the original.  You won't find advanced encoding settings anywhere in this interface, so if you're looking to fine-tune your output, I recommend moving on to something like Handbrake, Format Factory, or FFCoder.

I would have loved to give this software 10/10 stars, however there was one negative aspect to Freemake Video Converter: the bundled Freemake Toolbar and OpenCandy softwares.  The toolbar is set to install by default unless you choose otherwise on the first page of the install wizard.  To their credit, the Privacy Policies and/or EULA's are easily available for all bundled software. OpenCandy, on the other hand, does not have a checkbox to toggle its install.  Instead, you'll have to roll up your sleeves and install from the command-line if you want to opt out of it.  Here's how:  Hit Start, then 'Run' the install file with the /nocandy switch.  It will still show you the EULA for it, however there will be an option at the very end of the install to 'not install' the software OpenCandy recommends for you.  Even without the /nocandy switch, you can still uncheck the box, but for some reason the switch will trade in the check-box for 2 separate radio button choices (Yes or No).  It's a lot to worry about and go through, but this software really is top-notch in most other ways.

Although their website defaults to an "online installer", they do host offline installers, available here.


FormatFactory ScreenShot Another excellent choice (especially for old phones and DVD ripping) is Format Factory. It has presets for over 100 devices, converts to and from dozens of formats, and allows for advanced tweaking and custom profiles. On the downside, the sidebar-and-popup interface does not provide a linear experience.  You'll find that you can not drag'n'drop into the windows that look like you should be able to, and you have to open & close a couple of windows in order to end up back at the starting screen, where you finally get to hit START.  This being said, once you learn the interface, you'll find it responsive, stable, and easy to drill down to the exact settings you are looking for. Overall, this program is a good choice for power or device users who find iwiSoft lacking.

NOTE:  When installing Format Factory, watch out for the bundled toolbar.  It is installed by default if you don't uncheck the box on the first screen of the installer package.

A portable version of this software is also available at LiberKey, which is a superb portable application manager.


Also recommended:

  • YouTube Downloader HD:  This program is a gem in the world of YouTube ripping.  It allows you to copy/paste a YouTube link, choose your video quality, and download it to your computer for future viewing.  In the latest version, you can now choose to have it automatically convert the .FLV file to an iPod/iPhone compatible .MP4 file, or an XViD .AVI for playback on many devices.

Custom-Oriented Picks

If you need to make complex, custom jobs, FFCoder is the standout choice for its coherence. Like most programs in this review, it has an excellent device preset list, the ability to convert multiple files at once, and a simple, sleek interface. Where FFCoder stands out is its support of highly advanced configuration for each of the dozens of video formats and codecs, down to lighting and rendering settings. Despite a few dependencies (listed below) and a steep learning curve for any tweaks past the presets, this is the best converter for almost any power user, device owner or not.

One of my favorite FFCoder features is the Directory Watch.  You can setup FFCoder so that it monitors a folder for files matching a filename pattern, which will be automatically converted using the selected settings.  It can be a bit confusing to set up, however I found I got the best results when setting the wildcard filename pattern to something other than *.* (such as *.avi).

There were two things I didn't like about FFCoder.  The first is that is always creates Start Menu entries in the Administrator account, regardless of which non-admin account is being used to install it.  This is fairly minor though, contrasted with all the powerful features.  The second drawback is that it seems to be less stable on 64-bit Windows systems every now and again.  I ran into .DLL errors and missing presets, which strangely were intermittent problems.  I've spoken with the author and it looks like many of these bugs will be worked out in the next release.


Also recommended:

  • XVID4PSP: Supports very many tweaks. Impossibly fragmented interface. Solid AviSynth support.
  • MediaCoder: Great for tech obsessive because of the tons of customizable features to convert from and to video audio formats. Support MP4, AVI, MP3, WMA, WAV, etc. and allow to adjust parameters. But if you're not familiar with the jargon and just want a hassle-free, simple-to-use free video converter, you may turn to others.

Audio-Only Picks

Pazera Free Audio Extractor is the audio-only program in the above-mentioned Pazera Video Converters Suite. It supports both video and audio input and output to many formats, and is slightly simpler than some of its sibling programs. Otherwise, it is perfectly identical.



Online Conversion Websites

Video to Mp3 I was asked to checkout a web site converter for Youtube and Dailymotion videos. This site is set up to convert video to four set formats Mp3(128 kbt/s & 256 kbit/s ), flv, mp4 and 3gp.

This is a wonderful idea, but does it work lets see....

I started the test with an Mp3 convert and WOW finished in a matter of seconds and my result was ready to download. Ok lets check out some of these other bad boy options. Next I selected the Mp4 option and clicked the convert button and nothing. EMMM I thought well it is a video conversion so it will take more time. I waited until the next day nothing. After a full 24 hours still nothing. I reloaded the page and recopied the URL started a new convert. After 6 hours nothing and then my browser crashed ooops. I started a third again after 24 hours nothing. I am not saying it wont work for you as different configurations of bandwidth, browsers etc may be different but don't get your hopes up.

Next up the flv now I was thinking that a lot of Youtube video is in format flv so this should be quick but again after 3 days and 3 tests I had 0 results. At least this time my browser did not crash lol. So without much Enthusiasm I tried the 3gp option and hey what you know it worked first time and quite quickly about 30 minutes.

Having said all this if anyone wants a Youtube video in basic no frills mp3 audio from a Youtube video then this is a viable option and simple to use just copy and paste a Youtube URL into box, choice format and click convert and when it is ready download finished product, easy.



Zamzar is an excellent website when you're on the run.  It doesn't allow you to customize the encoding settings, however it makes up for that somewhat with its portability and flexibility.  If you have a browser with internet access, you have Zamzar.  If you have any file, you can convert it to any other type of file in the same class.  For example, you can convert video files, audio files, photos (ex: .JPG to .PNG), archives (ex: .RAR to .ZIP), documents (ex: .PDF to .DOC), and eBooks (ex: .LIT to .EPUB).  You can even paste a URL (ex: YouTube) and it'll download the embedded video for you and convert it.  Once the conversion is done, they email you a link to download the finished product.

This email-based file retrieval can be either a pro or a con depending on how you look at it.  It's more fuss than there really needs to be in the process, however it gives you the flexibility of converting a Youtube video from a computer where you can't download the content, such as when at work behind a proxy or at a public library.  When you get home, you can then download the finished conversion immediately using the email link.  I first used Zamzar over a year ago, and to this day I have never received unsolicited email from them.

There is a 100MB file limit for free use, but you can upgrade that to 200MB and get about 5GB of online storage if you want to pay their fairly steep monthly prices.  For most users, the free services are more than adequate.



Tested and not recommended:

  • MPEG Streamclip: very powerful for MP4, but single-file, ugly/laggy, has dependencies
  • Avidemux: great video editor, lousy video converter

Freemake worked fine for a quality video (720p), but when i tried an FLV 640x480 with mono audio, it multiplied the size by 5, even when using to FLV Same as Source.

All i want is to cut out unwanted parts and make the file as small as possible while keeping the exact same quality.

Video to Video converter is a software for converting between various video and audio formats:

Thanks, Panzer. I've actually tested this freeware but sadly I decided not to recommend. It supports plenty of video audio formats, but the device profiles are to some extent not up-to-date. And I think the profiles are also not that well organized, users may feel not easy to find out a certain one. Regarding the editing feature, it is also very basic compared with other converters.

Thanks the same for your recommendation. 

Already suggested in comments below.

try supersimple video converter
light weight , and really simple to use

Thanks, anuragdoc. I will take it into consideration. If it's good enouth, I'll include it in the list.

I've spent a whole day to test the programs listed in this article and removed quite many due to various reasons. Some were bundled with adware, some were not powerful enough nowadays (less profiles, less supported formats, etc.), some were slow or of large sizes, and so on.  Hope you'll like my hard work. :p

I've removed iWisoft Free Video Converter from General Converter Picks section to Tested and not recommended section. That is because:
1.  It has stopped upgrading since the end of 2010.  
2. The device profiles in the current version v1.2 are too old, you can't find the latest devices. I think it won't meet most of our needs, right?
But for those who like this free video coverter, you can still keep it and convert videos to your up-to-date devices. 
Note that you need to manually adjust the output settings for your devices for better viewing experience. 

Good morning you all.
Just received a note from " Update News" as follows:
Video to Video Converter is a great free tool for converting your video content
It is a freeware and I wonder what is wrong with this converter that it is not on your list of recommended converters.

Thanks arieshfman for your suggestion. I will download and test it myself and may include it in the review list if it's good enough.

I wonder if iWisoft has been abandoned because it hasn't been updated for years now ?

Thanks for commenting here, Sir Winston. I also have no idea about this. But I think for such long-time-no-updating programs, I may try to replace them bit by bit. If you're looking for a video converter, you can have a look at other programs. :)


Hi, so glad to see you here. I'm Arata, the new editor of this Best Free Audio Video Format Conversion Program category.  I will go on working with this review and bringing you the best freeware for video audio converting. If  you have any ideas or suggests, please also do not hesitate to share here. :)

After using Freemake for quite some time,and being pleased with the results, I finally consented to an update that they had been nag screening about for months. Big Mistake. Along with the update came a vicious piece of malware/adware
called "Express Find". It caused a black rectangle to appear at the bottom center of my (FF) browser screen which protruded about 2" from bottom and about 4"wide. There was an "X" in upper right hand corner but it did not close the rectangle. When clicked it redirected my browser to some very shabby websites. (per WOT) . Got rid of it by running avast scan which picked it up and deleted it. Beware


Just ran an MBAM scan. It found and quarantined 15 items classified as "PUP's" all connected to "Express Find" although previous to this scan browser appeared to be running cleanly.

In my opinion, the best video conversion program for most tasks is VLC, it's free, robust, and not full of malware like many of the free programs out there. It does most every format.

Thanks for the videoconverter analysing and rating, it's great! I tried two versions of Freemake Video Converter and then 4.1.3 to convert mov to avi, dvd to avi, mpeg2 to avi. Freemake Video Converter worked great with Win7-64, but crashed then and again when I tried to merge up to hundred mpeg2 files even without converting. Once I had luck to merge 90 mpeg2 with primary size 2.36 Gb. But only once. So, then I tried older version Freemake Video Converter 4.1.3 and it works well. Only problem was the bounded soft like new browser or toolbars. So, I needed to unistall some of them and run Ccleaner to clean my registry. Freemake Video Converter is great for your handycam, pretty fast and easiest, completely automatic, but for torrent movies converting I prefer XviD4PSP5 - better adapting quality, wide settings, choosing audio streams, etc. Thanks again!

Shouldn't this list be updated? It's been more than a year and also SUPER seems to be the only software that can work with the vp9 codec, but installing it makes my antivirus go crazy.

This review currently has no editor so there will not be any substantial updates to it until someone volunteers to take it over. MC - Site Manager.

I have tried just about all of the converters that is availiable I believe. I have stuck with [edited] for Dvds. I have never had a single problem out of it and I have problem converted a couple hundred movies. Plus it supports all formats, whereas some of the others do not. For audio I use XmediaRecode, and have not had a problem out of it. FF should never have been built. Handbrake does ok once you figure it, but still faults at times and has actually caused me to lose parts of a movie file.

[Moderator's note: Edited out mention of commercial software.]

Please be aware that Emsisoft Antimalware showed warnings while I've been installing Freemake Video Converter.

The most critical of them are:
-keylogger acticity;
-getting the listing of "My documents folder";
-windows service injection attempt;
-Opencandy installation attempt.

Thank you. We already highlight the bundled components in the Freemake product details. MC - Site Manager.
Combine an FFmpeg powered back-end with VLC rendered previews, then add in file size estimation, a gorgeous user interface and make it entirely free. That is Adapter - the ultimate converter app for Mac and PC:

I have tried many versions of Freemake and they all crash while loading MPEG2(ripped DVD using DVD Shrink) files (4-5 files around 4GB total). I've tried it on two different Windows 7 machines. Both crash. Five stars? Have not tried any of the older versions to see if that solves the issue.
My personal preference is MediaCoder. You must know a little about video formats and should invest some time on the website's Tips and Guides blog.

I've been using Format Factory for several years and recently updated the software. During installation I was given the option to install the Ask toolbar, which I UNchecked. Despite UNchecking the option, FF installed the insidious toolbar anyway. For some reason, uninstalling the Ask toolbar also uninstalled all my Firefox extensions. Despite having a FF backup, it took me 3 hours to restore all my customizations. Format Factory's brute force installation of the Ask toolbar is cheap and dishonest. I'll never use Format Factory again.

I just tried using this tool: Video to Video Converter

Looks like it belongs on this list.

Video Converter - Introduction

This is a free video converter. Video to Video converter is a software for converting between various video and audio formats. Today there are a lot of different video and audio formats, different devices support various video formats, therefore in order to watch video and audio material on different devices you need to convert it, which means to adjust it to the device being used.

Video converter which we present is feature-rich and allows you to convert almost all existing formats. It is possible to convert video and audio files to DivX or XviD format for watching movies on TV, HD formats for LCD, Plasma TVs, almost all types of mobile phones, android, iPhone, iPod, iPad, to prepare videos for the internet, conversion/authoring of video DVD formats, QuickTime, convert for uploading to YouTube, various rare and specific codecs etc.

XMedia Recode and XviD4PSP are the best among the ones I've used :D

My personal top pick is Mediacoder. It has an annoying nag screen when you start it up, but aside from that, it's perfect. Any format to any format, clear interface, full range of options (container, video stream, audio stream with all their tweaks and settings), GPU acceleration where possible, native interface (unlike iWisoft or Freemake for example with their lame custom UI), batch jobs, etc.

Edit: aaaand it turns out you can disable the nag screen, so now Mediacoder has lots of upsides and no downsides at all :3

What makes Mediacoder bettern than Freemake?

Tried to download Pazera audio converter / extractor 3 times yesterday and once today, and was never able to do it. I was immediately taken to a page where I could download a free video converter, but that was not what I wanted. On the off chance that the video converter might have the audio converter embedded in it, I installed it, but it did not.

What is the story here ? I am looking for a simple freeware program to convert wav or wma files to varying bitrate mp3 files. Used to use Musicmatch Jukebox, but that is no longer in existence.

Thanks for any suggestions.


I was able to download Pazera Audio Extractor from its page without any problems, using the link given in the article. Did you click on the right button? I hope you are using some sort of ad-blocker, because without it, there is a misleading Download button that can be seen, which is just for advertisement. There is however, the real Download button, which is on the top RHS, and if you hover your mouse over it, you can see the link leads to Pazera Audio Extractor download, and below it is the link for portable version. Other options are fre:ac - which is a free audio converter, as well as a CD ripper. Another is TAudioConverter:
