Convert JPEG to AVIF in this browser
Convert JPEG to AVIF when this browser can encode AVIF. Use AVIF for modern sites. Skip it if a form wants JPEG only.
JPEG to AVIF on imagecropx is a dedicated converter, not a generic “pick a format” clone of every other pair. You choose a JPEG file, the tab decodes it, and it writes AVIF with the Canvas pipeline used by the rest of the catalog.
You start from JPEG because that is the file you have. Use AVIF for modern sites. Skip it if a form wants JPEG only.
