FileOptimizer Portable

FileOptimizer is an advanced file optimizer featuring a lossless (no quality loss) file size reduction that supports hundreds of file formats including audio, video, images, databases, office formats, and more. FileOptimizer compresses already compressed files further without changing the file format, and being totally compatible. It keeps the behavior of the file untouched, but with its size reduced thanks to several recompression and optimization techniques. Both the 32-bit and 64-bit versions are included for maximum performance and compatibility.
