Free AVIF to JPG Converter
This free tool converts AVIF images to JPG in your browser, which is what you need when something refuses to open an AVIF: older phones, Office, most print shops, and a surprising number of upload forms.

AVIF files — add as many as you like
Runs entirely in your browser. Your images are never uploaded to a server.
How it works
- Drop the AVIF on the box above. Windows often reports no file type for an AVIF, so this reads the file itself rather than trusting the label.
- It is decoded and re-encoded as JPG immediately, at the quality you choose.
- Download it, and it will open in anything made in the last thirty years.
Common use cases
- Sending an image to somebody whose phone or laptop shows a blank square instead of a picture.
- Uploading to a form that rejects the file without explaining why, which is usually an AVIF being refused.
- Getting a photo into Word, PowerPoint or an older version of Photoshop, none of which read AVIF reliably.
- Sending artwork to a print shop, where JPG and TIFF are still the two formats anyone expects.
- Saving a picture from a modern website that serves AVIF, so you can actually use it afterwards.
Frequently asked questions
- Why will nothing open my AVIF file?
- Because it is genuinely new. AVIF is built on AV1, a video codec finalised in 2018, and browser support only became near-universal around 2023. Operating systems moved slower than browsers did: Windows needs an extension from the Store to show AVIF thumbnails, and plenty of desktop software has never added it. So you end up in the odd position where a file downloads perfectly from a website and then nothing on your computer will open it. Converting to JPG ends the argument.
- Will the JPG be bigger than the AVIF?
- Almost certainly, and often by a lot. AVIF is roughly half the size of a JPG at matched quality, which is the entire reason websites serve it. Converting back to JPG gives up that efficiency in exchange for opening everywhere. If the file size matters more than compatibility, keep the AVIF and install a viewer instead.
- Does converting lose quality?
- A little, and it is worth understanding why. Both formats are lossy, so the AVIF has already discarded detail, and the JPG then discards more on top of what is left. This is generation loss, and it is the same reason a photocopy of a photocopy degrades. One conversion at high quality is close to invisible; converting back and forth repeatedly is not. Convert once, from the original, and keep that original.
- What about transparency?
- AVIF can store transparency and JPG cannot, so anything transparent is filled in rather than kept. If your AVIF has a transparent background, convert it to PNG instead, which keeps it intact.
- Should I just use PNG instead?
- Only if you need transparency or the image is a screenshot or a flat graphic. For a photograph, PNG will produce a file several times larger than the JPG for no visible benefit, because PNG stores every pixel exactly and a photograph has no repeating areas for it to take advantage of.
- Where does the conversion happen?
- In your browser. The AVIF is decoded by the same code your browser uses to display one, then re-encoded through the Canvas API. Nothing is uploaded and nothing is kept.
