    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).

    Saving images for web/email/other media with the best compression ratio and quality is a difficult task if you don’t have the right tools. Choosing the right format then choosing the right parameters are the key factors of smaller files.

    Comments about UPX as an Alternative to FileOptimizer

    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.
