FileOptimizer is an advanced, all-in-one file optimizer/compression tool featuring a lossless (no quality loss) file size reduction. It supports more than 275 file types, and has more than 45 third-party file compression plugins built-in, allowing you to get the best possible results.

FileOptimizer is suitable for home users that need to speed up file transfers no matter if they are in email attachments, P2P or shared upload servers. It's also suitable for webmasters/web developers that need to increase the page load speed and reduce content weight.

By default, FileOptimizer will remove additional metadata, and other unneeded information, but will keep original files in your recycle bin just in case you want to further modify the originals.
