How to convert AVIF to JPG
- Drop your AVIF files onto the box above, click to browse, or paste an image from your clipboard.
- Set the JPG quality slider, 90% is a safe default; drop it for a smaller file or push it to 100% before editing.
- Download your JPGs individually, or use Download all to save a whole batch at once.
Why do AVIF files exist, and why convert them?
AVIF is the newest mainstream image format, and it's a genuine leap: derived from the AV1 video codec, it compresses a photo to roughly half the size of a JPG, often much less, at the same visual quality. Performance-obsessed sites have jumped on it, which is why a right-click "Save image" increasingly drops a .avif onto your disk instead of a familiar JPG.
That efficiency becomes a headache the moment you try to use the file. Older Photoshop builds, the default Windows photo viewer on many machines, office suites, print services and a long list of upload forms simply don't recognise AVIF yet, its support is real but younger than WebP's. Converting to JPG sidesteps all of it, giving you a file that opens on anything.
Your browser already knows how to decode AVIF, so this tool reads it natively and re-encodes to JPG in about a second, entirely on your device. Two side effects to expect: any transparency is flattened onto white (JPG has no alpha channel), and the JPG comes out larger than the AVIF, that's the cost of swapping a newer, more efficient codec for a universally compatible one.
AVIF vs WebP vs JPG: how they compare
All three can store the same photo; they just sit at different points on the size-versus-reach curve:
- AVIF, smallest files and the best detail-per-kilobyte, plus transparency and wide colour. Weakness: the youngest, so support outside browsers is still patchy.
- WebP, nearly as small, and by now supported almost everywhere on the web and in most modern apps. A sensible middle ground if you want the file to stay light.
- JPG, the largest of the three, but it opens on literally everything, from ancient software to photo printers. The right target when compatibility beats size.
If your goal is a small web-ready file rather than maximum compatibility, consider WebP as an alternative destination, or compress the JPG you get here down to an exact limit with Compress to 100KB.
Frequently asked questions
What is an AVIF file and why can't I open it?
AVIF (AV1 Image File Format) is a modern format built from the AV1 video codec. It produces extremely small files, so speed-focused websites increasingly serve it, which is why a right-click save can now hand you a .avif. Many desktop editors, office apps, printers and upload forms don't accept it yet, so converting to JPG makes the image open everywhere.
Does converting AVIF to JPG lose quality?
At the default 90% the difference is practically invisible. AVIF is already lossy-compressed, so the JPG is a second lossy copy of what you already see on screen; keep quality at 90% or higher and it stays imperceptible. The resulting JPG will typically be noticeably larger than the AVIF.
Why is the JPG so much bigger than the AVIF?
Because AVIF is one of the most efficient image formats there is, often about half the size of a JPG at the same quality, and sometimes far less. Going back to JPG trades that efficiency for compatibility, so the file grows. If you need it small again for the web, WebP is a good middle ground.
What happens to an AVIF's transparency?
AVIF supports transparency, but JPG does not, so any transparent areas are flattened onto a white background during conversion. If your AVIF has a see-through background you need to keep, convert it in an editor that can export PNG instead.
What quality setting should I pick?
90% is the safe default, visually identical to the AVIF with a reasonable size. Lower it toward 80% for the smallest plain-photo file, or raise it to 100% if you plan to edit the JPG afterwards.
Are my AVIF files uploaded to a server?
No. Your browser decodes the AVIF natively and re-encodes it as JPG locally, so the image never leaves your device. There's no sign-up and no limit on how many files you convert.
