JPG vs AVIF
JPG · JPEG
JPG (JPEG) is a lossy format tuned for photographs. It throws away detail the eye barely notices to reach small file sizes, but it has no transparency and re-saving repeatedly degrades quality.
AVIF · AV1 Image File Format
AVIF is built on the AV1 video codec and is one of the most efficient image formats available — often 50% smaller than JPG with better quality, plus transparency and HDR. Encoding is slower and support, while broad, is slightly newer than WebP.
