Frequently asked questions
Why is AVIF compression slower?
AVIF encoding is very thorough, which is why the files are so small. Large photos can take several seconds each on a phone.
Can I turn other images into AVIF?
Yes. Add PNG, JPEG or WebP images and choose AVIF as the output format.
Are my files uploaded?
Your files stay on your device. Conversion runs inside your own web browser, so your files are never uploaded to our servers or anyone else’s. Nobody can see them, and nothing is stored after you close the tab.
Is it free?
Yes, it’s completely free. There’s no sign-up, no watermark and no limit on how many files you convert. Each file can be up to 1 GB.
