About this tool
AVIF can produce even smaller files than WebP at similar quality. Encoding is slower, so this tool processes one image at a time in your browser and shows the saving for each.
Frequently asked questions
Should I use AVIF or WebP?
AVIF is often smaller; WebP encodes faster and has slightly wider support. Many sites serve AVIF with a WebP or JPG fallback.
Why is AVIF conversion slow?
AVIF compression is computationally heavy. Large photos can take several seconds each.
