AVIF to JPG Converter

Why you ended up with an AVIF

You almost certainly saved an image from a website. AVIF is the format modern sites increasingly serve because it is dramatically smaller than JPEG at the same quality, and your browser handles it without ever mentioning the format. The problem starts the moment the file leaves the browser: Windows Photos on older builds, Photoshop without a plugin, most print shops, a great many upload forms and almost every piece of software written before 2022 will simply refuse it.

Converting to JPG trades away AVIF's size advantage for the one thing it lacks — being accepted everywhere.

What the conversion costs

AVIF and JPEG are both lossy, so this is a re-encode rather than a copy, and generation loss applies. The output is written at quality 92, which is high enough that the difference is invisible at normal viewing sizes on photographic content. The file will get substantially larger — often two to four times — because JPEG's 1992-era compression cannot match what AVIF does. That is the price of universal compatibility, and it is usually worth paying for a file you need to send somewhere.

Keep the AVIF if it is your only copy. Convert a duplicate, not the original.

Transparency is flattened onto white

AVIF supports an alpha channel and JPEG does not, so any transparent area is filled with white before encoding. If the image has transparency you care about — a logo, a cutout, a sticker — convert to PNG instead, which keeps the alpha channel intact.

Animated AVIF gives you one frame

AVIF can hold an animation, much like a GIF. JPEG cannot. If the source is animated you will get its first frame, which is the only sensible single-image answer.

Nothing is uploaded

Your browser already knows how to decode AVIF — that is why the image displayed in the first place — so the conversion is a local decode and re-encode on a canvas in this tab. No copy is transmitted. Open the Network panel while converting and the only outbound request you will see is this site's own anonymous page-view ping.
