PNG is a wonderful file format that suffers from an unfortunate gamma problem (http://hsivonen.iki.fi/png-gamma/ ). PNGpong alleviates this issue by stripping the color “correction” information out of the file using pngcrush. PNGpong then attempts to further compress the PNG file by running it through optipng (I say “attempts” because some PNG’s may already be as compressed as possible).
Simply drop one or more PNG files onto PNGpong and it’ll take care of the rest.
By default, PNGpong will create a new optimized file with “_PONGED” on the end of the filename. If you would like, there is a preference to overwrite the original file instead.
