Convert AVIF to JPG
AVIF is the most efficient image format in common use — and the least widely supported by desktop software. Convert to JPG here when you need a file that opens anywhere.

How to convert AVIF to JPG
- Select your
.aviffiles. - Choose a quality level, and a background colour if transparency is present.
- Press Convert and download.
Decoding uses your browser's built-in AVIF support where available, which is fast and adds nothing to the page weight. Only if your browser lacks it is a WebAssembly decoder fetched, and only at that moment.
What AVIF is
AVIF wraps still images in the AV1 video codec. It is roughly 50% smaller than JPEG and 20–30% smaller than WebP at matching quality, and it supports HDR, wide colour gamut, 12-bit depth and transparency.
The trade-off is encoding cost — AVIF is much slower to encode than JPEG — and patchy support outside browsers. Most desktop image viewers and editors still cannot open one.
What gets lost in conversion
JPEG is 8-bit, SDR and has no alpha channel. Converting from AVIF therefore means:
- HDR is tone-mapped down to standard dynamic range;
- wide-gamut colour is clipped toward sRGB;
- 10- and 12-bit depth is reduced to 8-bit, which can introduce banding in smooth skies;
- transparency is replaced by your chosen background colour.
For ordinary photographs none of this is visible. For HDR content it can be.
AVIF vs WebP vs JPEG
| Format | Relative size | Transparency | App support |
|---|---|---|---|
| AVIF | 100% (smallest) | Yes | Mostly browsers only |
| WebP | ≈ 130% | Yes | Broad |
| JPEG | ≈ 200% | No | Universal |
If the destination is a website, keep the AVIF or convert to WebP — both work in every current browser and save real bytes. If the file is going into desktop software, to a print shop, or into an official upload form, JPG is the only safe answer.
Batch conversion
Drop up to 20 AVIF files at once, convert them in a single pass, and download them as a ZIP. Because decoding uses your browser's built-in support, this is fast and adds no libraries to the page.
Frequently asked questions
Are my images uploaded to your server?
No. The image is decoded, processed and re-encoded by your own browser using the Canvas and Web Worker APIs. There is no upload endpoint for this tool — open your browser's network panel while you use it and you will see no request carrying image data.
Why can't I open AVIF files on my computer?
Browsers adopted AVIF quickly; desktop software has not. Windows needs the AV1 Video Extension from the Microsoft Store, and many editors have no support at all.
Will the JPG be much larger?
Yes — expect roughly double, sometimes more. AVIF is a far more efficient codec, and that efficiency is exactly what you give up for compatibility.
What happens to my file when I close the tab?
It is gone. The image only ever exists in your browser's memory as an object URL; closing or refreshing the page discards it. Nothing is written to our servers, and nothing is stored on your device unless you download the result.
