ICO is a Windows-specific icon container, while AVIF's AV1-based compression produces some of the smallest file sizes available for a given visual quality, making it useful when archiving or publishing a large library of icon and logo designs where storage efficiency matters. Converting ICO to AVIF extracts the icon's largest embedded resolution and re-encodes it with AVIF's modern compression.
AVIF also supports a full alpha channel, so transparency from the original icon carries over, though AVIF encoding takes longer than simpler formats due to its more advanced compression algorithm.

Frequently Asked Questions
Why archive icon designs as AVIF?
AVIF's efficient compression keeps a documented icon or logo archive smaller, which matters once you're storing many designs from various past projects.
Will my icon's transparency carry over to AVIF?
Yes, AVIF supports a full alpha channel, so transparency from the original ICO file transfers to the converted file.
Can I convert an entire folder of ICO files to AVIF at once?
Yes, Batch Mode handles entire folders, including nested sub-folders, and scales conversion speed across multiple CPU cores.
