AVIF to PNG Converter
AVIF in, universally readable PNG out, transparency intact.
Your files stay in this tab. There is no upload endpoint on this site.
The right direction when transparency matters
AVIF carries a full alpha channel, and so does PNG. Converting between them keeps every soft edge and every partially transparent pixel exactly as it was — which is why this, rather than AVIF to JPG, is the conversion to reach for when the image is a logo, an icon, a cutout product shot or anything else that is meant to sit on top of something.
Only the encoding is lossy, and only once
AVIF is a lossy format, so whatever it discarded is already gone. PNG is lossless, so this conversion adds nothing further: the PNG stores exactly the pixels the AVIF decoded to. No generation loss accumulates, and re-saving the PNG later will not degrade it either. That makes PNG the better choice if the file is going to be edited rather than just viewed.
Expect a much larger file
This is the trade, and it is a steep one. AVIF is one of the most efficient still-image formats in use; PNG compresses losslessly with an algorithm from 1991. A 200 KB AVIF photograph can easily become a 3 MB PNG. For flat graphics — logos, icons, line art — the gap is far smaller, because that is content PNG handles well.
If you need both transparency and a small file for the web, WebP is the middle ground: it keeps the alpha channel and lands much closer to AVIF in size.
Why the file would not open in the first place
AVIF is what modern websites serve because it is small, and browsers decode it silently. Outside the browser the support picture is much patchier: older Windows builds, Photoshop without a plugin, most print services and a long tail of upload forms all reject it. PNG has been universally readable for three decades, which is the entire point of this conversion.
Nothing is uploaded
Decoding and re-encoding both happen in this tab, using the same AVIF support your browser uses to display the image. The file is never transmitted anywhere.
Common questions
Do my files get uploaded to a server?
No. Every tool on this site runs entirely in your browser using the Canvas and WebAssembly APIs. There is no upload endpoint in the page — you can confirm this yourself by opening your browser's Network tab while you convert a file. Nothing leaves the tab, which also means the tools keep working if you go offline after the page loads.
Is transparency preserved?
Yes, in full. Both formats store an 8-bit alpha channel, so soft edges and partial transparency come through exactly.
Why is the PNG so much larger?
PNG is lossless and uses a general-purpose compressor from 1991. AVIF is lossy and uses a modern codec. A ten-fold increase on photographic content is normal.
Does converting lose quality?
The conversion itself loses nothing — PNG stores the decoded pixels exactly. Whatever the AVIF discarded when it was created is already gone and cannot be recovered.
