AVIF to JPG Converter

Convert AVIF images to JPG in your browser so software that has never heard of AVIF can finally open them.

Files you drop here are processed by your own browser. Nothing is uploaded and nothing is stored on our servers — the tools keep working even if you lose your connection after the page has loaded.

How to use AVIF to JPG

  1. 1Drop your .avif files onto the box above, or click to browse for them.
  2. 2Set the quality and the colour that will replace any transparency.
  3. 3Press apply if you changed a setting, then download each result or take the batch as a .zip.

Why you need to convert AVIF to JPG at all

AVIF is the newest of the mainstream image formats, built on the AV1 video codec, and it is genuinely the most efficient of the bunch. That efficiency is why sites serve it and why you keep ending up with .avif files you did not ask for: right-click and save an image from a modern site and this is often what you get.

Then the trouble starts. Browser support arrived years before anything else caught up. Windows shows a grey placeholder until you install a codec from the Microsoft Store. Older macOS versions cannot generate a Finder preview. Most photo editors, almost every print workflow, and a long list of upload forms and CMS back ends simply refuse the file. JPG is the format that has never had this problem anywhere.

What the conversion costs

Two things, and both are worth knowing before you start.

The file gets bigger, usually two to four times. AVIF earned its size advantage with a much more modern codec, so re-encoding the same picture as JPEG needs considerably more bytes. There is no setting that avoids this. It is the price of compatibility.

Quality drops a little. The AVIF was already lossy, so writing a JPEG puts a second generation of lossy compression on top. At the default 92 percent this is difficult to spot in a photograph. In a screenshot or a graphic with hard edges it is much more visible, and for those you want PNG instead.

Transparency needs a colour

AVIF can store an alpha channel and JPEG cannot, so any transparent pixel has to be filled before the JPEG is written. The control above sets that colour and defaults to white. If the image is headed for a dark page, choose a dark colour now rather than discovering a white halo later.

JPG and JPEG are the same format

Mentioned because it splits the same question across two searches. The three-letter extension survives from filenames that allowed only three characters after the dot, and there is no difference in format, quality or compatibility. A search for avif to jpeg and a search for avif to jpg are asking for the same output, and this page treats both extensions identically.

Nothing is uploaded

Your browser already contains an AVIF decoder, which is the reason this works without a server. The file is decoded, drawn to a canvas and re-encoded in the tab, so no copy of it goes anywhere.

Frequently asked questions

Why can nothing open my AVIF file?
AVIF is only a few years old. Browsers adopted it quickly, but desktop software did not. Windows needs a separate codec from the Store, older macOS builds cannot preview it, and many editors, printers and upload forms still reject it outright.
Will the JPG be bigger than the AVIF?
Almost certainly, often two to four times bigger. AVIF is currently the most efficient of the common formats, so anything you convert it to will need more bytes for the same picture.
Does the picture get worse?
Slightly. You are re-encoding lossy data with a different lossy codec, so a second generation of compression is unavoidable. At 92 percent quality it is very hard to see on photographic content.
Can this tool create AVIF files?
No, and neither can any browser-based tool reliably. Browsers can decode AVIF but cannot encode it from a canvas, so every output here is PNG, JPG or WebP.
