Apps with 'PNG Compression' feature

  1. Paint.net is a free and very capable image editing software for Windows. Great alternative to Photoshop for people that do not need all the stuff PS offers.
  2. 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).


  3. Compress and compare images with different codecs, right in your browser.
  4. FreeArc is a free and open source file archiver developed by Bulat Ziganshin. It uses LZMA, PPMD, TrueAudio and GRzip algorithms with automatic switching by file type, and also uses set of filters—for instance it can remove repetitions from text.
