FileOptimizer is a broad format file compression tool used to reduce file size without changing the quality, known as "lossless." This is done via wide variety of optimization and recompression tools and techniques. Original files are sent to the recycle bin for restoration in the event the uncompressed version is preferred. A list of the 400+ supported formats include audio/video (MP3, OGG, M4A), image (GIF, JPEG, PNG), office formats (DOCX, XLSX, ODT, PDF) and system files (DLL, EXE).

Supports drag-and-drop of files into the window or onto the program icon. Note that by default the program removes metadata for many file types. This information reduces overall file size and protects privacy but is important to some users (e.g. photographers) and file search tools.

A 64-bit version is available within the folder, the author reports the program is functional in WINE, and can be used on the command line.

System Requirements: WinXP / Vista / Win7 / Win8 / Win10 / Wine
Writes settings to: Application folder
Stealth: ? Yes
Unicode support: Yes
License: GNU AGPL
How to extract: Download the self-extracting 7z package and extract to a folder of your choice. Launch FileOptimizer32.exe or FileOptimizer64.exe (for 64-bit OS).

At startup, the program will optionally show ads to support program development. These can be disabled at any time.

Optionally, to save space:
  • 32-bit systems: delete FileOptimizer64.exe and the \Plugins64 folder
  • 64-bit systems: delete FileOptimizer32.exe and the \Plugins32 folder
  • Delete unnecessary language files

That's not portable. I can only get a setup file installing in C: drive.

@Special do you mean that even if ads are not shown they are loaded?

Looks like version 11.40 phones home on every startup now, regardless of settings, probably trying to fetch some ads, well I'm not giving it a firewall rule so I'll be sticking with version 11.31 for the time being.

Sorry guys. Will not post changelog here anymore.

I've been meaning to make a similar observation for a while... also the forum topic (accessible via the "double balloon dialog" button next to it) is more adequate for keeping record of related stuff.

FileOptimizer 11.30 is out, beware of the new URL:

- Moved to a new HTTPS enabled website at
- Switched code to support HTTP and HTTPS.
- Added integrated ads display, since some users wanted to support FileOptimizer and do not have Paypal. You can remove if you want.
- Added HideAds=false INI setting to remove ads.
- Added GUI option to remove ads.
- Disabled Windows error handling, so when a plugin crashes, FileOptimizer execution does not get stopped (Garret Wilson and others).
- Disabled/deprecated themes because they are not stable. I will remove all asociated code in next release.
- Reduced reminder frequency.
- Workarrounded ImageMagick GIF processing flags (Devedse).
- Fixed default process priority set to idle, even if it should be normal (RejZoR).
