AVIF to JPG, in your browser
AVIF is a newer image format that many websites now serve because it is very small. The catch is that a lot of software – older Windows photo viewers, Word, many upload portals – still cannot open it. Converting to JPG gives you a file that works everywhere, at the quality you choose. Decoding uses your browser’s built-in AVIF support (current Chrome, Edge, Firefox and Safari).
How to convert AVIF to JPG
- Add the AVIF files. Click the sheet or drag them in. You can add other formats in the same batch.
- Check the quality. 92 % is visually identical; 100 % for no recompression at all.
- Convert and download. Each file becomes a .jpg with the same name. Several files arrive as a ZIP.

Frequently asked questions
Why can’t I open an AVIF file?
AVIF support is still missing from many apps, including older versions of Windows Photos, Microsoft Office and many web forms. Browsers can display it, which is why this converter works.
Will the JPG be bigger than the AVIF?
Usually yes – AVIF compresses much better than JPG, so the same picture may be two to three times larger as a JPG. That is the price of compatibility.
Is the AVIF file uploaded?
No. The image is read and converted by your browser on your own device. Nothing is sent to a server, and nothing is stored.
Can I convert several AVIF files at once?
Yes. Add as many as you like; each becomes a JPG, and they download together as a ZIP.
Is there a size or daily limit?
No limits and no watermark. Very large images (over about 50 megapixels) may be slow on older phones because the work happens on your device.
