I don't know if I understood correctly your question, but although GIF
uses LZW instead of zlib (LZ77 iirc), it can stand only for 256
different colors - hence it my be smaller than PNG, as PNG allows 32bit
colors fine (being 8 for alpha). JPEG is dependant on lossy compression
(at least the actual implementations; I think a lossless was proposed,
but I've never seen it), then sure it can be much smaller than PNG.
