How to convert AVIF to JPG

  1. Add your AVIF files

    Drop .avif images onto the box above, or click it to choose them. JPEG is already selected, so they’ll come out as .jpg files that open anywhere.

  2. Press Process

    The default quality of 85% suits sharing and uploading. For photos you’ll print or edit, set 90–95% first. Then press Process.

  3. Download the JPGs

    Save each file with its download button, or press Download ZIP to get them all. photo.avif becomes photo.jpg.

Where AVIF files come from

AVIF is a newer image format, first published in 2019, that stores photos in far fewer bytes than JPG. That’s why many websites and image services now send AVIF to any browser that can show it. Right-click a picture, choose Save image as, and you may get a .avif file even though the page looked like any other.

You’ll also meet AVIF from image editors and compression tools that export it, including this site’s own JPG to AVIF converter. Web designers use it to make pages load faster; the trouble starts when the file leaves the web.

Apps and sites that can’t open AVIF

Support has grown quickly, but it’s far from universal. You’re likely to have trouble with:

  • Older computers: Macs before macOS Ventura (2022) can’t open AVIF in Preview or Photos, and Windows only includes AVIF support from the 2022 update to Windows 11.
  • Photo editors and viewers: many, especially older versions, can’t read AVIF at all.
  • Upload forms and online services: job sites, official forms, printing services and marketplaces often accept only JPG or PNG.
  • Other people: someone else’s phone, computer or email app may not open an AVIF you send them.

A JPG works in all of these, which is why it’s the safe format for sharing, printing and uploading.

Your browser needs to support AVIF

The conversion happens in your browser, which has to open the AVIF before it can save it as JPG. Every current browser can: Chrome since version 85 (2020), Firefox since 93 (2021), Edge since 121 (2024), Safari on iPhone and iPad since iOS 16 (2022), and Safari on Mac since version 16.4 (2023).

In an older browser the file can’t be read, so it won’t convert, and you may see a message saying the browser can’t open AVIF images. Update your browser, or open this page in a current one. Nothing needs installing either way.

What changes when AVIF becomes JPG

  • The file gets bigger. JPG needs more bytes for the same picture. At 85%, 22 test photos went from 983 KB as AVIF to 1.3 MB as JPG, and a smooth landscape photo from 12 KB to 53 KB. That’s expected, not a fault.
  • Transparency turns white. JPG can’t store it. If your AVIF has a transparent background, choose PNG above instead, which keeps it.
  • HDR is flattened. AVIF can hold HDR brightness and more than 8 bits of colour; the JPG is a standard 8-bit sRGB image, so HDR photos lose their extra brightness.
  • Lost detail stays lost. AVIF is usually compressed with loss, and converting can’t bring back what it discarded. The JPG adds a little compression of its own, which is very hard to see at 85% and above.
  • Hidden details aren’t copied. Any date, camera or location data in the AVIF is left out of the JPG.

Choosing the JPG quality

85% is right for sharing, email and upload forms. For printing or further editing, 90–95% adds less compression of its own; the 22 test photos came to 1.6 MB at 90%. Going to 100% is rarely worth it: one 12 KB AVIF became a 361 KB JPG at 100%, against 66 KB at 90%, and it can’t hold more detail than the AVIF had.

If a form has a size limit, convert first, then shrink the JPG to fit with the image compressor, or go straight to compress to 100 KB.

Frequently asked questions

What is an AVIF file?

An image in the AV1 Image File Format, published in 2019 by the Alliance for Open Media. It uses the same compression as AV1 video, which makes photos much smaller than JPG at the same quality, so websites use it to load faster.

Why won’t my AVIF file open?

The app you’re using doesn’t support AVIF yet, which is common with older computers, photo editors and upload forms. Convert it to JPG here and it will open anywhere.

Why is the JPG bigger than the AVIF?

AVIF compresses photos far more efficiently, so the same picture needs more bytes as JPG. In tests the JPG was between 1.4 and 4.3 times the size at 85%, with smooth images such as skies growing the most.

Will the JPG look worse than the AVIF?

Not noticeably at 85% or above. The picture is compressed once more, which loses a little detail, but rarely enough to see. Use 90–95% if you plan to print or edit it.

Should I convert AVIF to JPG or PNG?

JPG for photos you want to share, upload or print. PNG for images with a transparent background, or graphics you’ll edit further. PNG files are much bigger: a 12 KB AVIF photo became 647 KB as PNG and 53 KB as JPG.

Can I convert AVIF to JPG on an iPhone or Mac?

Yes, in Safari on iOS 16 or later, or Safari 16.4 or later on a Mac. Open this page, tap the box to choose your AVIF files and download the JPGs. Older versions of Safari can’t read AVIF, so update first.

Can I convert AVIF files saved from a website in bulk?

Yes. Add as many as you like, press Process once and use Download ZIP. Files are converted one after another on your device, and none of them are uploaded.
