FileOptimizer is an advanced file optimizer featuring a lossless (no quality loss) file size reduction that supports an absolutely staggering array of file formats. I counted at least thirty formats but the application supports many more than that and also includes a plug-in mechanism which can enhance the app’s capabilities even more.
What does FileOptimizer do?
FileOptimizer compresses already compressed files further without changing the file format and retaining complete compatibility with their originals. It keeps the behavior of the file untouched, but with its size reduced thanks to a collection of recompression and optimization techniques. FileOptimizer runs natively under the Windows operating system and can also run under Linux and macOS using WINE.
