AVIF to JPG Converter

AVIF is a newer image format built on the AV1 video codec. Websites and CDNs serve it because it produces very small files at high quality, often smaller than WebP and roughly half the size of JPG. Every current major browser shows AVIF, so while you are browsing, you never notice.

The problems start after you save the image. Older versions of Windows and macOS, many photo editors, office suites, email clients and web forms do not recognise .avif files. You get a blank thumbnail, an error, or a form that silently rejects the upload.

JPG is the most widely supported photo format there is, so converting AVIF to JPG is the most reliable way to make an image usable anywhere. The JPG will be larger than the AVIF, often two or three times, because it uses older compression. It will still be much smaller than a PNG of the same photo.

Your browser decodes the AVIF, draws it onto a canvas and saves a JPG at a high quality setting (about 90). Because your own browser does the work, the file is not uploaded. This also means the browser must be able to read AVIF: any current Chrome, Edge, Firefox or Safari (version 16 or later) can. If you see "Failed to load image", update your browser or try a different one.

• Transparency: JPG has none, so transparent areas are filled with white.
• Animation: animated AVIF files are saved as a still JPG of the first frame.
• HDR: JPG is a standard dynamic range format, so HDR AVIF images are converted to standard range and very bright highlights may look flatter.
• Size: pixel dimensions do not change. Use Resize Image or Compress Image if the JPG is too large for a form.

If AVIF files seem to appear out of nowhere, it is because websites decide the format on the fly. When your browser requests an image, it tells the server which formats it understands. Many sites, image CDNs and site frameworks then send the smallest format your browser supports, which today is often AVIF.

So the same image can arrive as AVIF in one browser and as WebP or JPG in another. Image search results, online shops, news sites and social platforms all do this. When you right-click and save, you get whatever the site sent, and the file name may not even end in .avif.

Practical tips:

• If a file will not open and you are not sure of its format, add it here anyway. If your browser can display it, it can be converted.
• Convert up to 10 saved images at a time instead of one by one.
• For logos and cut-outs with transparent backgrounds, use AVIF to PNG, since JPG turns transparency white.
• If a site gives you WebP rather than AVIF, use WebP to JPG in the same way.
