GIF = Graphics Interchange Format. GIF is used to pack 8-bit images using lossless compression.

GIF comes in two forms:

  • GIF87, which is the normal format.
  • GIF89a, which adds a single-color transparency.

GIF is quite obsolete by now, and while there are still plenty of GIFs around, you really should be using PNG as its replacement, since it offers much better compression, up to 48 bits colordepth, per-pixel transparency information, and all sorts of other goodies.
