What is AVIF, and why can I not open it?

It is a modern image format built on the AV1 video codec, and it is genuinely good — a photo at the same visible quality is often half the size of the JPG. Websites adopted it quickly because it makes pages faster. Desktop software moved much more slowly, so a file that displays fine in your browser can be unopenable in the photo editor sitting next to it.

Will I lose quality converting to JPG?

A little, and it is worth understanding why. AVIF is lossy and JPG is lossy, so this is a second generation of compression on top of a first — not a copy, a re-encode. At the quality this tool uses the difference is very hard to see on a photograph, but it is not nothing. If the image matters and you have the choice, convert to PNG instead: it will be much larger, but nothing further is discarded.

Why is the JPG bigger than the AVIF was?

Because AVIF compresses better. That is the entire reason websites switched to it. Getting a 1.2 MB JPG out of a 400 KB AVIF is the expected result, not a fault — you are trading size for the ability to open the file.

What happens to a transparent background?

It is lost. AVIF can store transparency; JPG cannot. Anything see-through is painted white, which is usually what you want on a photo and definitely not what you want on a cut-out product shot. For those, convert to PNG instead — same tool, same page, different button.

Is it free, and is my image uploaded?

Free, no account, no limit on how many files. Your browser does the decoding and the encoding itself. Your files are never uploaded.

Convert AVIF to JPG

AVIF is what a lot of the web now serves, which is why images saved from a browser increasingly arrive in a format that Photoshop, Windows Photo Viewer and half the apps on your machine will not open. Your browser reads it perfectly well — it is the one that downloaded it — so it can also hand you a JPG that everything opens.

How to convert AVIF to JPG

Add your AVIF files

Drag in whatever you saved. They are read by your browser and never uploaded.
Leave it on JPG

Or switch to PNG or WebP if you would rather. JPG is the one that opens everywhere.
Save the results

One at a time, or the whole batch as a zip.

What you get

A file your software will open

That is the whole job. JPG has been readable by everything since the nineties: every photo editor, every printer's upload form, every marketplace listing, every phone, every operating system that predates AVIF by twenty years.

No decoder to download

Every current browser already decodes AVIF — that is why AVIF exists on the web at all — so this page uses the one you already have. Nothing is downloaded, nothing is installed, and the first file converts as fast as the hundredth.

A whole folder in one pass

Saved thirty images off a site? Drop all thirty. They convert one after another so a large one cannot run your browser out of memory, and they come back as a zip.

Your files are never uploaded

No upload step, no queue on someone's server, no copy of your picture left behind in a temporary folder you cannot see. The conversion happens in this page.
