Understanding GIF Format, LZW Compression, and Color Quantization Techniques

The GIF format, introduced by CompuServe in 1987, uses LZW lossless compression and a block‑based file structure supporting 256‑color palettes, transparency, and animation, while efficient color‑quantization methods such as octree trees dramatically speed encoding compared to slower median‑cut algorithms without sacrificing visual quality.
