Output format: avif
AVIF is the format the modern web moved to: roughly half the bytes of a comparable JPG, with far cleaner gradients in skies and shadows. Feed it the JPEG your camera or phone produced and get back an .avif ready to drop into a site, an app or a Core Web Vitals budget. The AV1 encoder is compiled to WebAssembly and runs inside this page.
Frequently asked questions
- Which browsers can display AVIF?
- Chrome, Edge, Firefox and Safari have all shipped support, so a current audience sees it fine. If you still serve very old browsers, keep the JPG too and offer both through a picture element.
- How much smaller does the file get?
- Photographs usually land 30 to 50 percent below a JPG of matching visual quality. Flat graphics and screenshots gain less, since JPG was already poor at those.
- Why does this take longer than other conversions?
- AV1 compression does far more work per pixel than JPEG does. A large photo can take a few seconds on this device, which is the price of the smaller result.
