Convert AVIF to PNG
Drop in your AVIF files and download PNGs. Your browser already knows how to read AVIF, so no extra download is needed and nothing is uploaded.
Conversion happens inside this page using your browser's own image engine. Your files are never uploaded.
How to use it#
- Drop your AVIF files onto the box above, or click it to pick them.
- Each file is decoded by the browser and written back out as a PNG.
- Download them one by one, or take the whole batch.
AVIF is ahead of most software#
AVIF compresses better than anything else in wide use, which is why sites have started serving it and why phones and cameras have started writing it. The rest of the software world has not caught up, so an AVIF often will not open in an image editor, a document, or a form that only knows the older formats.
PNG is the opposite case. It is nobody’s favourite for file size and it is the format everything can read, which makes it the right thing to convert to when the goal is simply to get the picture into another program.
Nothing is lost, and the file gets bigger#
PNG is lossless, so the pixels the browser decoded are the pixels you get. The catch is that AVIF is extremely efficient and PNG is not, so a 200 KB AVIF can easily land as a 2 MB PNG. That is the format doing its job rather than a fault in the conversion.
If the file is going back onto a website, keep the AVIF. Convert for the specific program that needs it and leave the original in place.
Transparency and HDR#
AVIF and PNG both carry an alpha channel, so a transparent AVIF converts to a transparent PNG with its soft edges intact.
High dynamic range is the one thing that does not come through cleanly. An HDR AVIF is decoded and drawn into a standard range canvas, so very bright highlights are compressed into ordinary white. Most AVIF files on the web are not HDR, but if yours came from a recent phone camera it may be.
Frequently asked questions#
Are my images uploaded anywhere?
#
No. The browser decodes the AVIF and encodes the PNG on your device, so the file never travels. The tool works offline once the page has loaded.
Why does my browser say the file cannot be read?
#
AVIF decoding was added to browsers around 2021, so an older browser will fail on the file rather than convert it. Updating the browser, or trying a current Chrome, Firefox or Safari, is the fix.
Why is the PNG so much larger than the AVIF?
#
AVIF is one of the most efficient formats there is and PNG stores every pixel in full. Ten times the size is normal. Nothing has gone wrong, and the image itself is unchanged.
Can I convert a PNG back into an AVIF here?
#
No. Browsers can read AVIF but cannot write it through the canvas, so no client-side tool can produce one without shipping a large encoder. WebP is the closest format that browsers do write.
Does transparency survive?
#
Yes. Both formats store an alpha channel, so transparent and semi-transparent pixels convert unchanged.
