FileOptimizer v10.10 Updated

  • 194MB (uncompressed)
  • Released on 28 Jul 2017
  • Suggested by I am Baas

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 long list of 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: Win2K / WinXP / Vista / Win7 / Win8 / Win10 / Wine
Writes settings to: Application folder
Stealth: ? Yes
Unicode support: Yes

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).

Optionally, to save space:
  • 32-bit systems: delete FileOptimizer64.exe and the \Plugins64 folder
  • 64-bit systems: delete FileOptimizer32.exe and the \Plugins32 folder
Similar/alternative apps: ArcThemALL!, PngOptimizer, RIOT
What's new?
  • Repacked portable version is now a 7-Zip EXE SFX instead of a ZIP file. Size reduced from 136MB to 66MB.
  • Updated:
    • pingo to 0.89 x86 and x64 versions;
    • To ECT 0.8.2 (da09899) x86 and x64 daily optimized builds;
    • ImageMagick to with HDRI support.

Outstanding, especially on PNG files and when used in concert with RIOT ( I've thrown a wide variety of files at this program and seen quite a bit of space saved. It's difficult to tell which supported files will compress by how much, but it's always important to test when posting web images or distributing files to large groups, saving a lot of bandwidth.

It seems like, although this program supports all those file types, the parameters seem only to be applicable to swf and gz files. I couldn't figure out how to work this on a jpg file. Anyone got a tip for me?


webfork 2013-07-14 16:05

BGM: More recent versions have an additional optimization in the options menu (arithmetic encoding) that make the encoded JPEGs incompatible with older viewers.

Neat, but buggy. On some .exe's it will compressed them awesome... by deleting 99% of the file. It did this on my biz card reader software, and IBM social notes software (I'm sure you can Google them to try it out). Also, on some files the percentages listed were way off. The file size was correct, but not the compression ration.

gregoryg72: could you post a screencap of that in forums? I've been compiling a list of asks for the program that I hope one day to point the dev to (if his contact page ever comes back up). Thanks.

@ webfork: Obviously you found a contact page ;)
One of your suggestions is part of the changelog (see "What's new?").

A similar open-source program (for images only) I have tried, which really does do what it says, is Caesium
I have only tried it with JPEG's, but really strained it by enlarging a central portion of compressed and uncompressed pictures by a ridiculous amount and in a side-by-side comparison, I was hard-pushed to see any difference.

v7.60.1252 (04/26/2015)
- Added INI option AlwaysOnTop=false to specify if FileOptimizer main Windows should stay always on top.
- Updated Leanify daily binaries.
- Adding files not working for the x64 edition due to some aggressive optimizations in C++ Builder with -O3.

Version number is actually 8.00 and not 7.00.

@Special: Sorry for typo.
@joby_toss: Thanks for correcting.

Can't start the app on WindowsXP - it misses BORLNDMM.DLL. Just plain adding of that .DLL doesn't resolve the issue...((
Any ideas for the solution?


Midas 2015-12-27 03:05

@kozak: did you try registering that DLL with Windows?
(e.g., "regsvr32 BORLNDMM.DLL" at the command line)

Most images and files I post to portablefreeware go through this amazing compression tool. When compressing PDF files, I strongly recommend enabling the lossy DPI compression settings (usually around 150 or 200 is fine for most documents).

Thank you very much for the 10.00 update. Indeed you were faster than me!

FileOptimizer 10.00 (5th anniversary release):

- Compiled with latest C++ Builder 10.2 Tokyo April 2017 Hotfix.
- Fixed the bug of chineese shortcut text caused by Embarcadero C++ Builder 10.2 Tokyo, issue in the Win64 version when "Link with runtime packages" is set to false.
- Improved GUI draw performance.
- Improved pingo lossy optimizations for JPEG and PNG.
- Improved gifsicle and gifsicle-lossy performance by allowing using more memory, and using several threads.
- Added nightly builds at the SVN repository, so they can be publicly tested (Jack, Ryan Morben).
- Updated gifsicle to 1.89 (custom build).
- Updated pngquant to 2.10.0.
- Updated to ECT 0.8.2 x86 and x64 optimized builds (thanks Malloc Voidstar).
- Updated Leanify to daily binaries.
- Updated SQLite to 3.19.3 x86 and x64 Visual C++ 2017 custom builds.
- Updated pingo to 0.88 x86 and x64 versions.
- Updated ImageMagick to with HDRI support.
- Upgraded distributions to 7-Zip 17.00.

I have updated nighly builds with some interesting changes to come in next release:
- Added ClearWhenComplete=false INI setting to autoclear file list when optimization completes (Lanette Fidrych).
- Added GIF options tab.
- Added Allow Lossy optimizations checkbox in JPEG tab.
- Reenabled Embarcadero's Luna, Metropolis and Windows 10 themes removed in FileOptimizer 9.10, because they work fine again with Windows 10 Anniversary and later.
- Fixed version display in About window.
