colorsquash is a tool for squishing your image into only 256 distinct colours,
allowing it to fit in a GIF or indexed PNG. It tries to do this with as little
change as possible. It's quite good! And often matches the input image very closely, but should
be considered an artists tool.
squash accepts input from png or jpg files and can output gif and png.
