Short: An optimizer for PNG files Author: glennrp@users.sf.net (Glenn Randers-Pehrson) Uploader: dmx404 gmail com (DMX) Type: gfx/misc Version: 1.7.73 Architecture: ppc-warpup Pngcrush is an optimizer for PNG (Portable Network Graphics) files. It can be run from a commandline in an MSDOS window, or from a UNIX, LINUX or Amiga commandline. Its main purpose is to reduce the size of the PNG IDAT datastream by trying various compression levels and PNG filter methods. It also can be used to remove unwanted ancillary chunks, or to add certain chunks including gAMA, tRNS, iCCP, and textual chunks.
