FileOptimizer compresses files without changing the file format and is fully compatible. The file size is reduced by several compression and optimization techniques.
FileOptimizer integrates with many plugins, allowing it to handle a wide variety of file formats. Optimized files are usually smaller than the original, or at worst comparable. It is easy to use and easy to automate.
FileOptimizer is a native Win32 application, compact and fast, and works portable with no external dependencies or access to the system registry. Available for free and open source.
Using FileOptimizer is quite easy, drag the files you want to optimize onto the file grid in FileOptimizer, right-click with the mouse to open the contextual menu, then click Optimize. It will process all supported and added files, and overwrite them with the optimized version. You can also add files and directories for processing on the program’s command line, or drag them to executable files.
By default, FileOptimizer will remove additional metadata and other information that is not needed but will keep the original file in your recycle bin just in case you want to change the original further.
