Why convert to AVIF?

AVIF is built on AV1, a newer video codec than the one behind WebP, and it shows: at the same visual quality, AVIF files typically come out 20-30% smaller than the WebP equivalent, with the biggest gains on photos. Every modern browser can display AVIF without issue, so there's no compatibility risk on the viewing side.

The one tradeoff is encoding speed — AVIF takes a bit longer to produce than WebP, especially across a large batch. For a single photo or a moderate set, the extra few seconds are a small price for a noticeably smaller file.
