How PZIP Compresses GIF

GIF uses LZW compression limited to 256-color palette. PZIP's frame-aware passthrough analyzes multi-frame GIFs for inter-frame redundancy. For single-frame GIFs, the LZW stream can be decompressed and recompressed with LZMA. The never-worse guarantee ensures GIFs are never enlarged.

History of GIF

Est. 1987Created by CompuServe

GIF (Graphics Interchange Format) was introduced by CompuServe in 1987 using LZW compression. Despite being limited to 256 colors, GIF became the dominant animation format on the web. The 2012 Unisys LZW patent expiration freed GIF for universal use.

Frequently Asked Questions

Can PZIP compress animated GIFs?

+

Yes. PZIP handles both animated and static GIFs. Animated GIFs benefit from inter-frame delta analysis.

Why are GIF savings small?

+

GIF's LZW is already effective for palette-based images. PZIP's wins come from metadata separation and frame-level optimization.
