Why convert JPG to AVIF?
AVIF is the latest-generation web image format. Compared to JPG at equivalent visual quality it's often 40-50 % smaller — the biggest single-file-size win since WebP showed up. Every current Chrome, Edge, Firefox and Safari renders AVIF natively, so for site assets, PWAs, and CDN-served photos the conversion is essentially free bandwidth.
Caveats: AVIF encoding takes longer than JPG (you'll feel it on bigger batches — give it a moment), and tools outside browsers still lag — Word docs, ancient email clients, and some corporate uploaders don't handle AVIF. Stick with JPG when you're sending the file to a person rather than a webpage.

Are my files uploaded anywhere?
No. Conversion runs in your browser using JavaScript and the Canvas API. Your files never leave your device. You can disconnect from the internet after this page loads and the tool will still work — try it and see.
Looking for something else? try WebP first if you need broader software compatibility.
