Convert AVIF to JPEG
Drop a AVIF file below and get a JPEG back. The conversion happens on your own machine, so nothing is uploaded and there is no size or quantity limit beyond what your browser can hold in memory.

Lower means a smaller file. 75 is a good default for photos.

Why convert AVIF to JPEG?
Plenty of websites, content management systems and older desktop programs reject AVIF uploads outright. JPEG is accepted just about everywhere, and that alone accounts for most of these conversions.
Expect the JPEG file to come out larger than the AVIF you started with. That is the price of the broader compatibility and simpler decoding JPEG gives you.
AVIF can carry transparency; JPEG cannot. Transparent pixels are composited onto white during conversion, so a logo with a see-through background will come out sitting on a white rectangle.
Both formats are lossy. Every re-encode discards a little more detail, so it is worth starting from the original rather than from a copy that has already been through this a few times.
AVIF vs JPEG at a glance
| Property | AVIF | JPEG |
|---|---|---|
| Compression | Lossy | Lossy |
| Transparency | Yes | No |
| Typical file size | 40-55% of an equivalent JPEG | 100% of an equivalent JPEG |
| Compatibility | All current browsers; some older desktop apps lag behind | Opens everywhere, including decades-old software |
| Usually comes from | Websites optimising page weight | Digital cameras and photo sharing |
Frequently asked questions
Are my AVIF files uploaded anywhere?
No. The decoder and encoder are WebAssembly modules that run inside this page. You can verify it by opening your browser’s network tab — converting a file produces no outbound requests. You could even disconnect from the internet after the page loads and it would still work.
Is there a file size or quantity limit?
There is no limit imposed by us. The practical ceiling is your device’s memory, since the image has to be held uncompressed while converting. On a typical laptop, images up to around 100 megapixels convert without trouble.
Will converting to JPEG lose quality?
JPEG is a lossy format, so some data is discarded. At the default quality setting the difference is not visible at normal viewing sizes. If you need an exact copy of the pixels, choose PNG instead.
Does it work on a phone?
Yes. The same WebAssembly modules run on mobile browsers. Conversion is slower than on a desktop because phone CPUs are weaker, and very large images are more likely to hit memory limits.
Where do AVIF files come from?
Almost always from a website. AVIF compresses better than anything else in wide use, so sites that care about page weight serve it. Cameras and phones do not produce it, which is why most people only meet AVIF when saving an image from the web.
What quality setting should I use?
For photographs, 75 to 85 is the range where most people cannot tell the result from the original at normal viewing size. Below about 60 you start seeing blocky artefacts around sharp edges. Above 90 the file grows quickly in exchange for very little visible gain.
