Why convert JPG to AVIF?

AVIF is the most efficient mainstream image format available: photographic images typically come out 40–50% smaller than the equivalent JPEG with no visible difference. It is supported by all current browsers, making it excellent for websites chasing performance scores. Encoding is more CPU-intensive than other formats, so large photos take a few seconds — all locally, with nothing uploaded.

Frequently Asked Questions

How much smaller is AVIF than JPEG?
For photos, AVIF at comparable visual quality is typically 40–50% smaller than JPEG and 20–30% smaller than WebP, making it the most efficient widely supported format.
Why does AVIF conversion take longer than WebP?
AVIF uses the AV1 video codec’s intra-frame compression, which searches much harder for savings. The encoder runs as WebAssembly in a background worker, so the page stays responsive while it works.
Where can I safely use AVIF images?
All current versions of Chrome, Firefox, Safari and Edge display AVIF. For websites it is safe today; for sharing with desktop apps or older devices, JPG or WebP remain the safer choice.
