Convert AVIF to PNG
Drop a AVIF file below and get a PNG back. The conversion happens on your own machine, so nothing is uploaded and there is no size or quantity limit beyond what your browser can hold in memory.

Why convert AVIF to PNG?
Plenty of websites, content management systems and older desktop programs reject AVIF uploads outright. PNG is accepted just about everywhere, and that alone accounts for most of these conversions.
Expect the PNG file to come out larger than the AVIF you started with. That is the price of the broader compatibility and simpler decoding PNG gives you.
PNG is lossless, so the conversion adds no new compression artefacts. Whatever detail survives in the AVIF file is carried across exactly.
PNG is the format most image editors and design tools expect, which makes it the practical choice when the file is headed for further editing rather than straight onto a web page.

Frequently asked questions
Are my AVIF files uploaded anywhere?
No. The decoder and encoder are WebAssembly modules that run inside this page. You can verify it by opening your browser’s network tab — converting a file produces no outbound requests. You could even disconnect from the internet after the page loads and it would still work.
Is there a file size or quantity limit?
There is no limit imposed by us. The practical ceiling is your device’s memory, since the image has to be held uncompressed while converting. On a typical laptop, images up to around 100 megapixels convert without trouble.
Will converting to PNG lose quality?
The original AVIF is already lossy, so some detail was discarded when it was first created. Converting to PNG preserves whatever is in the AVIF file exactly, but it cannot recover what was lost earlier.
Does it work on a phone?
Yes. The same WebAssembly modules run on mobile browsers. Conversion is slower than on a desktop because phone CPUs are weaker, and very large images are more likely to hit memory limits.
Where do AVIF files come from?
Almost always from a website. AVIF compresses better than anything else in wide use, so sites that care about page weight serve it. Cameras and phones do not produce it, which is why most people only meet AVIF when saving an image from the web.
Why is the PNG bigger than the original?
PNG is lossless, so it stores every pixel exactly instead of approximating them. For photographs that usually means a file several times larger than a lossy original. PNG earns its keep with screenshots, logos, line art and anything needing transparency — not with photos.
