How to use this tool

Worth the wait
AVIF encoding is much slower than JPG. Large photos can take several seconds each, because the encoder runs on a single thread in your browser rather than on a server.
Frequently asked questions
Do browsers support AVIF?
Yes. Current versions of Chrome, Edge, Firefox and Safari display AVIF.
Why is it slow?
AVIF trades encoding speed for compression. Everything runs on your device, so speed depends on your processor.
Are my images uploaded?
No. Encoding runs inside your browser.
