When to use this tool
- You need a AVIF file because the destination (a website, CMS, app or printer) expects AVIF.
- You want the best compression available today — often half the size of WEBP — ideal for hero images, large galleries and bandwidth-sensitive sites.
- You're moving photos out of JPG into a more widely compatible format.
Best for
- Next-gen websites
- Large hero images
- Bandwidth-heavy galleries
- Sites that already have a JPG fallback
Every image you drop here is processed entirely inside your browser using the standard Canvas and File APIs. Nothing is uploaded, stored or logged on a server — you can disconnect from the internet after the page loads and the tool still works.
Quality & file size notes
- • AVIF uses lossy compression. Quality 85–92 is visually identical to the source for almost every photo — drop below 70 and you'll start to see softness on faces, gradients and text edges.
- • Both JPG and AVIF are lossy, so the image is re-encoded. Use quality 90+ to keep the result indistinguishable from the source.
Things to watch out for
- — AVIF encoding is slower than JPG/WEBP. Older browsers (Safari < 16, IE) cannot display AVIF — serve a fallback for them.

Why convert JPG to AVIF?+
AVIF offers the best compression available today — often half the size of WEBP, which makes it ideal for hero images, large galleries and bandwidth-sensitive sites. JPG on the other hand is supported by every browser, app and printer ever made, so converting gives you a file that fits the destination better.
Will I lose quality converting JPG to AVIF?+
Both formats are lossy, so the image is re-encoded once. Stick to quality 90+ and you won't see a difference from the original.
