Frequently asked questions
Does it work in every browser?
Yes. Browsers cannot save AVIF on their own yet, so the tool uses its own encoder (about 3 MB, loaded the first time you convert).
Is the image sent to a server?
No. Encoding happens entirely on your device; large images may take a few seconds.
