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.


Say what you will... but GIFs and JPGs are what most people use. I'm not a techie... and have been living/working on the internet for years (as a user)... and I've never even heard of PNG. -- MatthewSimpson

Well, around here all of the techie population uses PNGs. Perhaps you are hanging around in the wrong techie groups :-).

-- JanneJalkanen

That's exactly it... I'm not hanging out in techie groups at all... I'm trying to make things like wiki work for non-techies... and if you look at the images searcher on Google, 70%+ of the rest of the world doesn't use PNG.
