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.
You have an AVIF that some piece of software refuses to open, and you need it in a format that has been around long enough for everything to understand — while keeping transparency, which rules out JPEG. PNG is the answer to that specific combination of requirements. It is also, by some distance, the largest file you could end up with.
Before you convert
This is the biggest size jump of any common conversion
AVIF is the most efficient format in wide use and PNG is among the least. Going directly between them means giving up everything the newer codec bought you: a 300 KB AVIF photograph can land north of 5 MB as PNG. If you do not specifically need lossless or transparency, WebP sits in the middle and will serve you better on both counts.
Lossless from here, but not lossless from the start
PNG will store the incoming pixels perfectly, and that is worth something if editing follows. It does not undo the lossy AVIF encode that already happened. What you get is a perfect copy of an already-compressed image — useful as a working master, not as a restoration.
HDR does not survive, even though PNG can hold deep colour
PNG supports 16 bits per channel, so depth is not the obstacle. HDR metadata is: PNG has no standard way to carry the transfer function and mastering information that tells a display how to present those values. An HDR AVIF converted to PNG comes out as a flat standard-range image, technically deeper but visually tamer.
What carries over
- Transparency
- Every pixel from here on
- Compatibility with almost all software
What does not
- A very large amount of compression efficiency
- HDR presentation
- Animation, if the source had any

Frequently asked questions
Are my AVIF files uploaded anywhere?
No. The decoder and encoder are WebAssembly modules that run inside this page. The network tab may show a codec downloading the first time you use a format, but no request contains your file. On supported browsers, a codec that has already been used is cached so the same conversion can work offline.
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.
