My friend Nick never could find a PNG image optimizer to his liking. We found the PNGpong dashboard widget, but Nick’s not a fan of the OSX dashboard so, being the swell guy that he is, he decided to make his own version and share it with you for free.
PngOptimizer is powered by the OptiPNG library and built with Ruby and Platypus and don’t flame Nick over the icon… he doesn’t like it that much either. The application will optimize any PNG (or folder of PNGs) dropped onto it. Once the optimization is complete, PngOptimizer will notify you via Growl with the total number of images it has optimized and how many kilobytes you have saved. Check it out and leave a comment if you would like to let him know what you think.
