How much smaller?
We ran a AVIF file back through our own engine at automatic quality and measured what came out. The format is unchanged — only the bytes.

Your own file will land somewhere else — a photo, a screenshot and a flat logo compress very differently. What carries over is the direction and the rough scale.
About the format
Built on the AV1 video codec. The smallest files of the five, often half the size of JPG, at the cost of slower encoding.
