Convert AVIF to JPG locally, in one step
AVIF gives you the smallest files available today, which is exactly why it can be a problem: an increasing number of upload forms, editors and messaging apps still have no idea what to do with one. Converting to JPEG is the reliable way to make the image acceptable everywhere — and it can be done without uploading the original.

Supports WebP, JPEG, PNG, and AVIF up to 50MB. Processed offline.
Output is preset to JPEG — change it after you drop a file.
How to convert AVIF to JPEG
- Add your image. Drop in a AVIF file — up to 50 MB, decoded on your device.
- Choose the output format. Pick JPEG in the Target Format row.
- Set quality or a size target. Use the quality slider, or set a target file size in KB if the destination has a limit.
- Compare before saving. The slider shows the original against the result so you can see what changed.
- Download. Save the JPEG file. Nothing was uploaded at any point.
What you give up, and what you gain
AVIF is the more efficient codec, so the JPEG will normally be a meaningfully larger file at the same visual quality. What you gain is reach: JPEG opens in essentially everything, including software that predates AVIF by a decade. That is the whole argument for converting, and it is worth being honest about the cost.
Because both are lossy formats, this is a decode followed by a new encode. Quality around 90 keeps the second generation of artefacts subtle. The comparison slider is the reliable check — look at text edges, skies and hair before you decide the result is good enough.
Film-grain and fine texture are what AVIF is best at keeping cheaply and JPEG is worst at, so noisy photos are the case where you will notice the difference most.
Can my browser even open AVIF?
Decoding an AVIF file is done by your browser, not by us, so a very old Safari or Firefox release may not display it. Current Chrome, Edge, Firefox and Safari all handle it. If the tool cannot read your file, the message says so rather than producing a blank result — and a newer browser will open it.
Encoding to AVIF is different and always works here, because that uses a WebAssembly copy of libavif shipped with the site rather than the browser’s own codec. Compressing to AVIF covers that direction.
Hitting a size limit while converting
If you are converting because a portal has both a format rule and a byte rule, set the target size before you download — the tool searches for the highest quality that fits, the same way the compress to 200KB page describes. One pass handles both requirements.
AVIF to JPG questions
Yes, with no limits on file count and no account. There is no server to meter, so there is nothing to charge for — the browser does the work.
It re-encodes, which is not the same as a lossless transformation. At quality 90 the visible difference from the AVIF is normally small; the file size difference is not, because AVIF is the more efficient format.
Yes — pick PNG in the Target Format row. That preserves transparency and gives an exact, lossless result, at a considerably larger file than either lossy option.
The file is read by your browser and never transmitted, so there is no upload to reason about. The verifiable version of that claim — watching the Network tab while a conversion runs — is in the no-upload guide.
