What is ICO to AVIF?

Evolving a legacy icon container into a next-generation web format requires extracting raster layers and re-encoding them with modern video compression. The source container stores multiple resolutions of uncompressed or PNG files. The target format utilizes the royalty-free AV1 codec to achieve high compression ratios. This conversion parses the icon directory, extracts the highest-resolution raster layer, and translates the pixel arrays into an AV1 bitstream, creating a highly compressed graphic that supports 12-bit color depth.
