JPEG to AVIF questions

What is AVIF?

AVIF is a modern image format based on the AV1 video codec. It produces files 50 to 80% smaller than JPEG at the same visual quality, making websites and apps load much faster.

Why convert JPEG to AVIF?

JPEG files are already compressed, but AVIF goes further. For the same visible quality, AVIF can cut the file size in half or less. That means faster websites, lower bandwidth and quicker loads on mobile.

Will converting lose quality?

At 60% quality or higher, most people cannot tell AVIF from the original JPEG. Use 70 to 80% for a great balance between size and quality.

Does AVIF work in every browser?

All modern browsers display AVIF: Chrome 85+, Firefox 93+, Safari 16.4+, Edge 121+. That covers 95% of users. Older browsers simply will not show the image.

How does your converter make AVIF?

We load a small WebAssembly encoder the first time you choose AVIF. It runs on your device, in your browser, with no upload. It adds about 400 KB once and works offline after that.

Are my images uploaded?

Never. Everything runs in your browser. Your files never leave your device.

Can I convert many JPEG files at once?

Yes, up to 20 files at once. Download them individually or all together as a ZIP.
