"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. Many images here on TPFC including our logo have been compressed using FileOptimizer."
