What is ICO to GIF?

Converting a multi-resolution Windows asset into a legacy network format requires decoding raster maps and applying color palette quantization. The source format can store multiple versions of an icon with 32-bit color depth. The target format is a legacy image format restricted to an 8-bit palette containing a maximum of 256 colors. This conversion extracts the largest image layer, quantizes the pixels to select the 256 best colors, and encodes the pixel indices using LZW compression.
