What does converting JPG to AVIF mean?
JPG is a lossy format optimized for photographs, while AVIF is a next-generation format based on the AV1 video codec offering the best compression of any mainstream image format. AVIF compresses photos significantly better than JPG with less visible quality loss.
JPG uses lossy compression tuned to how the human eye perceives detail, producing much smaller files than PNG for photographic content. It doesn't support transparency, and repeated re-saving can introduce visible compression artifacts over time.
AVIF routinely produces files 50% smaller than JPG at the same visual quality, and supports transparency and a wide color range. Browser support is strong in all current major browsers, though very old software may not display it.
