How AVIF compares to HEIC

AVIF is generally similar in nature to HEIC. The main differences are file size, quality characteristics, and transparency support.

Quality recommendations

For AVIF output, start at the balanced preset and adjust to taste. A lower quality setting shrinks the file further; a higher one keeps more detail. Keep the original HEIC file for archival edits.

Is conversion private?

The HEIC is decoded to AVIF on your own machine. Both codecs run locally, so nothing is transmitted.
