PDFConvertersOnline.comHow to convert AVIF to JPG
- Select the .avif files you saved or received.
- JPG is the chosen output. Change quality or background color if needed.
- Convert, then download the JPGs or a ZIP of all of them.
Where AVIF files come from
AVIF is showing up more and more because it's so efficient: websites and image CDNs send it to browsers that can display it, and a growing number of image editors and design tools can export it. When you save such an image, you get a .avif file. Browsers show it happily, but the next step often fails. An older photo editor won't open it, a web form says the format isn't allowed, or a colleague on an older computer just sees an unknown file icon.
JPG solves that. It is the most universally supported photo format there is, from decades-old software to printers and smart TVs.
How the conversion works
The page first asks your browser to decode the AVIF. Current Chrome, Edge, Firefox and Safari can do this natively. If yours can't, the tool falls back to an AVIF decoder bundled with the page, so the conversion still works, just a little more slowly. The decoded picture is then saved as JPG by the browser at the quality you set (90% by default). All of it happens on your device; the image is never transmitted.
Transparent AVIF images
AVIF supports transparency; JPG does not. If your AVIF has see-through areas, such as a product on a transparent background, they are filled with the background color you select. White suits most online listings and documents. If you need to keep the transparency, convert with AVIF to PNG instead.
Expect a bigger file
AVIF compresses far more tightly than JPG, so the new file will usually be larger, sometimes several times larger. That's the price of compatibility, not a sign that something went wrong. If the JPG is too big for an upload limit, lower the quality to 75–80% or use Compress Image to reach a precise size. Also note that some AVIF images use HDR or wide color. JPG stores standard 8-bit color, so extremely bright highlights may look a bit flatter after conversion.
Batch conversion
You can convert a whole folder of AVIF images in one go. Files are processed one after another, each result shows the old and new size, and a ZIP download collects everything. If a single file is damaged, it's marked in the list while the rest still convert. An animated AVIF becomes a single JPG of its first frame. And if JPG isn't what you need after all, the same page can also produce PNG, WebP or a re-encoded AVIF.

Frequently asked questions
Why can't I open AVIF files on my computer?
AVIF is newer than most desktop software. Recent operating systems and browsers support it, but many image viewers and editors, especially older versions, do not yet.
Does AVIF to JPG lose quality?
A little, since JPG is lossy. At the default 90% the difference is not visible in normal use.
Will the JPG keep the same dimensions?
Yes, the width and height in pixels stay exactly the same.
My browser doesn't support AVIF. Will this still work?
Yes. When the browser can't decode AVIF, the page uses its own built-in decoder, which runs locally too.
Can I choose the background color for transparent parts?
Yes. When JPG is selected, a Background option appears. White is the default; you can switch to black or pick any color.
Are the original AVIF files kept?
Yes. The tool reads them and creates new JPG copies; nothing on your device is overwritten or deleted.
