  Spr2Png 26bit 32bit BASIC C updated 2006-5-5

Download v0.26 (0.25/0.08/0.11) (here) (signature) (source)

Converts sprites to PNGs, and Draw and Artworks files to sprites or PNGs, with optional default background colours; also converts PNGs to sprites. (Most sprite types are supported: specifically, spr2png understands CMYK sprites and the Select alpha channel format, but 24bpp packed RGB and JPEG are not supported.)

All of the PNGs on this site were created using this program; some were optimised using pngcrush.
