What is HEIC to GIF?

Translating a modern high-efficiency mobile photo into a legacy graphic format involves a major reduction in color depth. The source format supports millions of colors and wide dynamic ranges. The target format is restricted to a rigid 8-bit palette containing a maximum of 256 colors. This conversion requires a color quantization algorithm (such as median cut) to analyze the image, select the 256 most representative shades, and map the pixels to indexed palette positions using LZW compression.
