About
Quantization is the process of intelligently mapping a wide range of colors down to a smaller set. Unlike brute-force color reduction, quantization algorithms pick the best representative colors so your GIF still looks good with fewer shades. This tool is ideal when you need to compress a GIF without making it look washed out or banded.

Pro Tips
Try 128 colors first — it is often a great balance between quality and compression for most GIFs
For GIFs with lots of gradients, quantization preserves smooth transitions better than raw color reduction
Use quantization as a first pass before applying dithering for the best visual quality at low color counts
