Saved an image and got an AVIF nothing on your computer opens? Convert it to a JPG that opens anywhere.

Where AVIF files come from

AVIF is a still-image format built on AV1, a modern video codec. Some websites and image delivery networks send AVIF to browsers that can display it, so right-clicking and saving a picture can leave you with a .avif file even though the page looked perfectly ordinary. The format is compact and capable, but many desktop programs, older phones, office suites and upload forms still cannot open it. JPG is the opposite: older and less efficient, but accepted almost everywhere.

How the conversion works on this page

There is no separate AVIF decoder here. Your browser reads the file itself, exactly as it does when it shows an AVIF on a website, and the decoded picture is then encoded as a JPG at the quality you choose. That keeps the page light, and it also means the conversion only works in a browser that supports AVIF — current versions of Chrome, Edge, Firefox and Safari do. Nothing is sent to a server for decoding; the file stays on your device the whole time.

What changes in the JPG

AVIF can store transparency, animation and high-dynamic-range colour. A JPG can store none of these, so transparent areas become white, an animation becomes its first frame, and the picture is saved as an ordinary 8-bit JPG, which means any extra HDR brightness range is not carried over. For everyday photos and graphics none of this is noticeable. The output keeps the original file name with _conv and a .jpg extension.

How to use it

  1. Drop in your AVIF files.
  2. JPG is pre-selected as the output.
  3. Save the results.

Your files are never uploaded

Everything runs inside your browser. Because the image never reaches a server, we cannot store it or look at it. That difference matters when the file is company material or a personal photo.

Frequently asked questions

What is an AVIF anyway?
An image format newer than WebP, based on the AV1 video codec. The files are small, but plenty of software still can't open them — which is how you end up stuck with one.
My file won't load.
The conversion relies on your browser being able to read AVIF. Current Chrome, Edge, Firefox and Safari all can — update your browser and try again. A file the browser cannot read is marked as unreadable in the list.
Why is the JPG so much bigger than the AVIF?
AVIF is very space-efficient, so the same picture usually takes more bytes as a JPG. Lower the quality if size matters; the list shows both sizes.
What happens to a transparent or animated AVIF?
Transparent areas are filled with white, and an animated AVIF becomes a still of its first frame. JPG supports neither transparency nor motion.
Is it free?
Yes. No account, no payment, no usage limit.
Are my files uploaded?
No. Everything happens inside your browser. A page that is already open keeps working even if you go offline.
How many images at once?
There is no count limit. Speed depends on your own device, because your computer does the work rather than a server.
