Drop AVIF images here or click to browse

Processed entirely in your browser. Never uploaded to a server.

AVIF opens fine in a browser and then stalls out the moment you try to reopen it somewhere older — a photo editor without AVIF support, a print workflow, software that's simply never been updated to handle it. PNG is the safest landing spot: lossless, alpha-capable, and readable by essentially everything that opens images at all.

Decoding happens on your device

The AVIF decoder is a WebAssembly build of libavif, downloaded once on your first conversion and then cached by the browser. It's a couple of megabytes, so the first file takes a moment longer than the rest. Nothing about your image is sent anywhere.

FAQ

Why can't I open my AVIF file?
Browsers all display AVIF, but plenty of desktop software still doesn't read it — older Windows builds without the AV1 Image Extension, most email clients, and a lot of older photo editors and print or print-shop workflows. PNG is about as universally readable as an image format gets, which is why it's the safer target when a tool flatly refuses AVIF.
Does this restore the quality lost when the AVIF was encoded?
No, and nothing can. Most AVIF files are encoded lossy, so whatever detail that encode discarded is gone. This conversion decodes the AVIF and re-encodes it losslessly to PNG — the PNG matches the AVIF's pixels exactly, but the AVIF's pixels were already an approximation of the original.
Does the transparency carry over?
Yes. AVIF and PNG both support a full alpha channel, so any transparency in the source AVIF decodes and re-encodes intact. If the AVIF had no transparency, the PNG won't either — that reflects the source file, not a limitation here.
Why is the PNG so much bigger than the AVIF?
PNG compresses losslessly and AVIF is a generation ahead on lossy compression efficiency, so trading AVIF for PNG usually multiplies the file size several times over. You're paying that cost specifically to get lossless, universally-openable pixels — not for a smaller file.

Going back the other way, for a website? Try PNG to AVIF.
