Convert AVIF to JPEG so any app can open it

Convert AVIF to JPG when a picture you downloaded will not open, or a form rejects it. AVIF is one of the newest image formats on the web, and large sites use it because the files are very small. Many desktop programs, older phones and upload forms still cannot read it.

Drop the .avif files here. You get JPG copies that open in Windows Photos, Word, PowerPoint and nearly every website.

What is AVIF?

AVIF is an image format based on the AV1 video codec. It comes from the Alliance for Open Media, a group whose members include Google, Apple, Microsoft, Amazon and Netflix. It compresses photos very efficiently and supports transparency, so image heavy websites like it.

Current Chrome, Edge, Firefox and Safari all display AVIF on web pages. Outside the browser, support is uneven. On Windows, the Photos app needs the AV1 Video Extension from the Microsoft Store before it shows AVIF, and many editors and office apps show an error or a blank icon.

Why convert AVIF to JPG?

  • Edit the image in software that does not read AVIF
  • Paste it into a report or slide deck that others will open on their own PCs
  • Upload it to a form, marketplace or print shop that accepts only JPG or PNG
  • Send it to someone whose phone cannot preview AVIF

Expect the JPG to be noticeably larger than the AVIF. That is the price of wide compatibility.

How to spot AVIF: the file name ends in .avif, or your computer shows a generic icon with no preview. Some sites send AVIF even when the saved name ends in .jpg. If such a file will not open, try Convert to JPG, which accepts many image formats in one place.

Transparent images and other formats

JPG cannot store transparency, so any transparent area in the AVIF becomes white. For logos or cutouts that need a clear background, use AVIF to PNG instead.

Running a website yourself? Keep AVIF on your pages and use JPG copies only where you need compatibility. If a JPG ends up too large for an upload limit, Compress JPG brings it down without changing the format.

AVIF to JPG: frequently asked questions

Why can't I open AVIF files on my computer?

Your browser can show AVIF, but many photo viewers and editors have no decoder for it, and older systems lack one completely. On Windows, Photos needs an extra Store extension. Converting to JPG gives you a file every program reads.

How do I convert AVIF to JPG without installing anything?

Open FileKiwi in a modern browser, drop the AVIF files in, and download the JPG results. There are no plugins, codec packs or apps to install, no account, and no watermark on the images.

Will the JPG lose quality?

JPG is lossy, so some fine detail changes, but at 92% it is very hard to see. Raise the slider if you plan to edit or print the image. Detail removed when the AVIF was first made cannot come back.

What happens to transparency in AVIF images?

Transparent pixels are filled with white, because JPG has no transparency. If you need the clear background, convert the file to PNG, which keeps it.

Is my file uploaded when I convert it?

Yes, a copy of each file is uploaded over HTTPS and kept in a private folder on our server for 30 days, then deleted automatically. The conversion itself runs in your browser, and the JPG files are not stored.

Is there a size limit?

Each AVIF file can be up to 50 MB, which covers even very large images. You can convert several files in one batch and download them together as a ZIP.
