    ImageOptim is excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). It's useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization).

    UPX is a pure exe packer while File Optimizer is a "multi file optimizer"! It is a pity that often the programs do not stick to the "theme"! This program has almost nothing in common with File Optimizer.
