AVIF is smaller than JPG. That's exactly why nothing opens it.

AVIF is the best image format almost nobody supports.

It came out of the AV1 video codec. Same compression tricks. A photo that's 800 KB as JPG can be 350 KB as AVIF. No visible difference.

Great. Except your client's Word 2019 won't render it. Your old Photoshop won't open it. Half the CMS platforms reject it on upload.

Where AVIF breaks

- Windows photo viewer before Windows 11: nothing.

- Photoshop before 2023: nothing.

- Most email clients: nothing.

- Old Android gallery apps: nothing.

So you download modern images, and half your tools shrug.

[FileTools](https://filetools.eu) converts without the drama

Drop your AVIF files on FileTools. Get JPG back. The conversion runs in your browser — the file never goes to a server.

No sign-up. No watermark on the output. No "upgrade to convert more than three files."

You can batch a whole folder. Download it as ZIP. Done.

When to keep AVIF

If you post to a modern site and control the stack, keep AVIF. It's better. Smaller files, faster pages.

Convert to JPG when the destination is old, strict, or unknown. That's most of the real world.

The bigger pattern

Every format war ends the same way. The new one wins on the web, the old one survives everywhere else. You need a converter that doesn't leak your files.

That's FileTools.

The same idea drives TubeVoice for video — making content work in languages it was never built for. And RoomFlip turns one room photo into a full redesign, no install.

Formats keep changing. Good tools just handle it.
