About this tool
AVIF is the most efficient image format browsers support: photos are often half the size of a JPG at the same quality, with transparency and smooth gradients without banding.
Encoding AVIF takes more work than other formats, so each photo needs a few seconds. Turn on “Extra compression” when you want the very smallest files and don’t mind waiting.
- Works on your device. Nothing is uploaded.
- Free, with no sign-up and no watermark.
- No limits on file count or size beyond what your device can handle.
Questions and answers
What AVIF quality should I use?
Around 55–65% gives photos that look like a high-quality JPG at a much smaller size. AVIF quality numbers aren’t the same as JPG ones, so lower values look better than you might expect.
Can all browsers show AVIF?
Current versions of all major browsers can. For very old browsers, serve a JPG or WebP fallback.
Is Convert to AVIF free?
Yes. Every tool on ImgImage is free to use, with no sign-up, no watermark and no limit on how many files you process.
Are my files uploaded anywhere?
No. Your files are processed by your own browser and never leave your device. Nothing you open here is sent to a server.
Does it work on my phone?
Yes. It works in any modern browser on phones, tablets and computers. Large files are processed faster on a computer.
