JPG to AVIF
Convert JPG to next-gen AVIF — usually smaller at the same quality, perfect for speeding up websites. Free, fast and secure, no sign-up. Everything runs locally in your browser and your file is never uploaded.
Higher = sharper but larger (PNG is lossless, no slider needed)
Your browser can't output AVIF (use the latest Chrome / Edge / Firefox).
Frequently asked questions
