How does color palette quantization reduce GIF file size?

GIF format uses an indexed color table (maximum 256 colors). By reducing the palette from 256 colors down to 64 or 32 colors using quantization algorithms, the entropy and LZW compression dictionary size decrease significantly, leading to 50% to 80% smaller file sizes with minimal visual degradation.

Are my animated GIFs uploaded to any remote server?

No. All image decoding, palette calculations, frame decimation, and compression execute 100% locally in your browser memory.
