Best Free File Rename Utility


In these days of MP3 libraries and vast collections of digital images, many of us have faced the necessity of renaming our files for organizational purposes. If you've come here looking for a solution we have some good news. There are great (and free!) programs to suit your needs.

There are many different methods to achieve the desired result, from laboriously renaming files one at a time using Windows Explorer, to bulk renaming utilities that can pull out metadata or execute powerful Perl based regular expressions. Some programs focus on simplicity and others are designed for power users. Most of the renamers support a basic set of features such as crop, insert, remove, replace, case changes, and auto number. And some renamers have more powerful features than others.

My rough guess is that about 95% of readers are mainly interested in bulk renaming MP3 files and pictures. While the remaining 5% (probably power users) rename thousands of files every day and have got their own favourite already. That's why the following reviews are focused on common users that are looking for an application to help with their music files and pictures.

Go to details...  Go straight to the Quick Selection Guide


File Renamer BasicFile Renamer Basic has a very appealing, polished interface that has a directory tree, a file listing, and tabs below. Beyond the basic features File Renamer Basic also supports regular expressions, ID3 v1 and ID3 v2, EXIF, renaming lists, saved profiles for repeat tasks, and ID3 tag editing which is a good feature. And, the help files are excellent.

A solid renamer altogether but not without some issues. For example, it could not find EXIF metadata for my images, there are no regular expression information or examples included in the help files, and it would be better if the undo, subfolder, and logging features were included in the free version.


Bulk Rename UtilityBulk Rename Utility has a cluttered interface and takes a little getting used to. You can choose files to be affected in the main window and drag files from Windows Explorer. It has an undo feature. Among many other basic features you can auto date, add a prefix or suffix, and move or copy to another location. Bulk Rename Utility supports custom file formats, logging, regular expressions, a few EXIF tags, and ID3 v1 tags. You can stack commands, zoom in to increase the size of a small text box, and modify file attributes, save frequently used configurations, and also import a file rename list.

Bulk Rename Utility is easy to use, powerful, and highly functional with excellent help files, suggestions, and examples. However the interface is a little messy, only supports a few EXIF tags, and there is no support for ID3 v2. I noticed some bugginess when attempting to rename MP3 files by their ID3 tags when there was no ID3 v1 data.


Advanced RenamerAdvanced Renamer has an attractive interface and works a little differently than other renamers. After you select the files you want to rename, you select the "Renaming method" you want to use. You then select pre-defined tags from multiple menus as commands. You can switch between methods to add different types of tags. The renaming is mostly menu driven and I found it very easy to use after getting the hang of it.

Its a little light on more powerful features but its easy to use. It only supports a handful of ID3 and EXIF tags. A very nice undo feature allows you to choose from a list which changes to undo. You can stack commands, map illegal file name characters, automatically display metadata, and change file attributes. It has a picture preview, supports file change lists, and has very good help files. Since v2.7 was introduced, support for regular expressions and natural sorting has been added. However, selecting files from a list to rename is clunky and you cannot select which ones you want to change as you can only remove them from the list.


PFrankPFrank is loaded with features and covers most of the renaming aspects. Besides all common renaming features PFrank supports meta data tags for many different file types. It can also modify meta tags and file properties.

The downside, affecting casual users for the most part, is that PFrank has a steep learning curve compared to the other renamers. Even the simplest rename will require a little studying of the help file. Nevertheless, technically minded users will pick up the syntax quickly enough to make it worth their while.


Other Renamers

Siren Siren is one of the most powerful renamers I have tested. For a power user with many and varied tasks to complete Siren will make your life a lot easier. On the negative side, Siren has a steep learning curve compared to other renamers. With what is in essence a library of predefined tags the simplest rename will require a little studying of the help file. Siren is no longer developed. No installation required.

Lupas Rename has a fairly intuitive interface and once you know your way around it, changing complex file names with this powerful utility is easy. I was unable to get the regular expressions to work on Vista or XP. Metadata tags are manually entered instead of choosing from a menu. Unfortunately, it appears Lupas Rename is no longer actively developed. No instalation is required.

ReNamer has a clean interface, supports a few different metatags and offers powerful PascalScript option for power users. Help files could do with improvement. I have not linked to this renamer as Norton reports the website as malicious. This could well be due solely to the nature of the products being offered, but we would advise caution when deciding to enter this site. No installation is required.

Metamorphose 2 Beta is more complicated to use than other renamers. I found myself reading help files more than actually doing any renaming.

Rename Master supports EXIF and ID3 tags, regular expressions and scripts. No installation is required.

Wild Rename is a very basic renamer that can perform tasks with support of regular expressions. It does not support EXIF or ID3 tags. No installation is required.

Flexible Renamer v8.2 supports invalid character mapping, file attribute modification, metadata tags for documents, imaging, and audio. Also supports VB scripts, Javascript, and regular expressions. Learning curve is too steep for what you get out of it.

CKRename v1.08 has a simple design and you can change file names, extensions, case, auto number, and use sting substitution but it doesn't have many advanced features.

Rename-It! v3.05 is a very simple program with just a few features. It has an intuitive interface and you can do simple cropping, case changes. It supports regular expressions and a few ID3 tags, both v1 and v2. Seems to work well for what it does but has less functionality than other renamers.

Ant Renamer v2.10 supports regular expressions, EXIF tags, and ID3 v1 tags. You can also change names from an imported file list. File change preview is limited to a single file and you cannot simultaneously view the commands and the file listing. No ID3 v2 support. Irritating bugs, for example, just open "Options", change anything and the language also changes.

A.F.5 Rename v1.1 is a simple renamer for basic day-to-day use. Actually it is too simple for my liking with no ID3 or EXIF support and no recursive file structure.

Multi File Renameris another basic renamer on our list. It does not support ID3 or EXIF tags, extensions or recursive file structure. Suitable for basic tasks.

There's one very old program (which still works just fine for me in Win7) that you didn't mention at all here, and from checking out the programs you've mentioned I think it might actually better than the whole lot of them! It has rather an odd name, "1-4a-Rename", but check it out, I think you'll be pleasantly surprised (note that it has both a basic and advanced mode, both of which are included in this freeware proggie)...

by MidnightCowboy on 11. June 2014 - 5:13  (116726)

I would advise caution as 1-4a Rename has not been updated for 8 years. MC - Site Manager.

Thanks for the review

Advanced Renamer has just been updated (March 26 2014).
It has also changed its URL to
The old URL (which is included in the review) automatically redirects to the new site.

Thanks a lot. Now updated.

Under "Other Renamers", you mention Siren. I agree that "Siren is one of the most powerful renamers". It does have a steep learning curve compared to other renamers but I am used to it now, having used it for years.

I can't agree with the statement "Siren is no longer developed"; the latest version, 3.14, was released on 27 December 2013.

You may want to review these programs again. Just looking at Advanced Renamer, it states that at the time of your review (Updated 4. July 2013) that it was "Last release: December 06. 2012" and it had actually had three releases in that time frame. It is now at version 3.60 as of Sept. 08, 2013 with a fair amount of changes since the Dec. 2012 release.

Does any of these renamers add context menu entries to conveniently rename files. I'd like one which adds a context menu entries to prepend files names with 5-6 different words, like Statistics, Marketing, Simulations, and Accounts.

I'd thank you a lot, and even send in a donation if possible, if you could point me to a software that does this...

I have tried most of the renaming utilities mentioned here, but i settled on rename master which combine ease to use interface and powerful renaming features , it has all renaming features, especially i like how text instructions in a way that is very informative and self-explaining, but one feature that i found very useful for me was the ability to import CSV list which i exported from excel as csv file of pre-defined filenames that i prepared earlier and then apply them to my existing list of files, it saved me a lot of time and effort and also it let manipulate strings the i want the filnames to be.

the renaming schemes are easy to figure out even for non-experienced users

Hi all,

Need advice and help... need to rename bookmark files from unidentifiable filename (eg. _______.htm ) to [something].htm , the new filename to be something from the link's http URL entries.

The aim is to restore all mis-named *.htm files under the Favaorite folder so that a readable bookmark can be then be recovered and exported.

Help! Any software/ideas appreciated!

Advanced Renamer rocks! I use it to rename my photos with the date/time at which they were taken, and it is very flexible. Took me 2 min to get used to the interface, and the preview is very useful. And it's being maintained. Fantastic.

I've used File Renamer Basic on Win7 for a year or so but lately, its started to crash all the time. The crashed program spins it wheels (and the CPU) until I kill it in Task Manager.

I note its not been updated in 2 years.

by David FB (not verified) on 16. July 2012 - 23:14  (96305)

Just tried Advanced Renamer. For my needs, I like it better than Basic.

by mrshortsales (not verified) on 5. July 2012 - 12:13  (95756)

I need to rename an entire folder structure (folder with subfolders and subfolders below them)... approx 8,000 folders in the tree all in all. I need a utility that can "find/replace" an illegal character. Folders include "&" in folder name. I need to replace "&" with "-" in those folders.

Any help is greatly appreciated.


by David FB (not verified) on 16. July 2012 - 22:59  (96304)

I noticed Advanced Renamer has a folder renaming tab. It should handle find and replace with no problem, though you may have to run file and folder rename separately.

File renamer for Linux

I came across this renaming utility called pyRenamer in the Ubuntu software center. I had to do some basic batch renaming which it did without a hitch. Found it to be a good alternative (for Linux) to Lupas rename, which I use in Windows.

The publisher's website says it is written using PyGTK for the Gnome desktop, but also works in any PyGTK enabled environment including Windows.

PhotoRenamer 3.0 is a freeware that rename your photos according to the date and the time you took the shot (from file date and time or Exif Data) and a Highy customizable Renaming Mask. Using an Explorer-like control, browsing the files is very easy and intuitive. Renaming Masks are strings that contains format specifications (Day, Month, Year, Hour, Min., Sec. Photo Number and free text) . File as 'IMG_01234.jpg' can be renamed as 'TGMDev-31-Dec-2011-16-51-26.jpg' or 'Lumix-FZ45-01234-2011-Dec-31-16-51-26.jpg'. PhotoRenamer 3.0 displays a picture preview with main picture data. Double-Click on the picture displays more than 60 Exif Data, including GPS data. Freeware guaranteed without spyware.

IMHO,Bulk Rename Utility is hard to use, documentation is minimal and support forum is difficult to search. IMHO.

by ron park (not verified) on 18. October 2012 - 12:17  (100984)

As for me, there have been two tools that had NO learning curve and were totally intuitive and forgiving:
Norton Commander (long long ago) and in the past years BRU. Like the other commenters, I'd suggest: spend half an hour playing with it and you won't regret it. It has but a few limitations, one of which which brought me here: adding random numbers or path informatieon to filesnames in subdirectories (e.g. I would like to make a collection of all my readme files in one folder). For general work though, Willsher's BRU is top!

by ManjunathBangalore (not verified) on 17. August 2012 - 13:52  (97853)

Sorry my friend. Bulk Rename Utility is the best of the lot. Just put half an hour of effort. You will not regret it. For me the moment Renaming question arises I go to this tool. Large number of features are provided in a single page. You need not search for it. Best tool. Just try once.

by Biggles2 (not verified) on 11. April 2012 - 4:25  (91883)

Hi Minnesota Bob,
It just looks hard to start with, once you have used it for hald an hour you will find it an excellent tool, very powerful ... and its free : ) I'd give it an 8 out of 10

I need to rename multiple PDF files with their title and author. Can anyone suggest the most suitable utility for this purpose?

by kidault (not verified) on 27. January 2012 - 13:52  (87886)

I've used Renamer(by den4b) for a while with FreeCommander. I can easily send files to it With FC. But when I looked the developer's site to look for newer version today, I'am regreted to find that it's only free for non-commercial usage.

After test several softs recommended here, I decide to replace it with Adveranced Renamer. It has the same logic as Renamer and accept file list as commandline argument. For me, "However, selecting files from a list to rename is clunky and you cannot select which ones you want to change as you can only remove them from the list." is not a con at all.

Rename Master is my first choice

by Anonymous2k (not verified) on 29. December 2011 - 0:53  (86144)

I am looking for a new version of Rename-it.
The program I got was made for windows 9x; it can work with XP, Vista and 7.
The author Kent H, last known version 3.1.1D Build date July, 10, 2001.
This utility was available in a zip file.
very useful, but I want this to be in full screen instead of a little window.
This other info:
[links removed]
may be outdated, do you have any idea if the author is still developing this utility or not?
I would like similar functions to this great utility for use in windows 7.
Thanks for your patience to read this comment, I hope there is a positive outcome

[edit] email address removed for safety reasons.

Removed the two links in your comment, as one of them lead to 404 page, and the other seems like its abandoned.

The link to Rename-it, as provided in the review, is this one :

The version on the link is 3.42, which is newer than what you have.

Also, the page says that a major version 4 is under development.
