How to use the AVIF to PNG converter
- Put your AVIF cut-outs in the queue.
- Resize under More settings if the overlay needs a particular width.
- Convert to PNG and download.
Soft edges survive
AVIF and PNG both support full transparency, so feathered edges, drop shadows and partly see-through areas come out as they were. That is the main reason to choose PNG over JPG here: JPG would paint every transparent pixel with a solid colour.
Whatever smoothing the AVIF encoder applied stays in the picture. PNG keeps the decoded image exactly; it cannot restore detail that was compressed away.
Size and a middle option
Expect a big jump: the PNG of an image can weigh ten times its AVIF or more. OxiPNG tightens each file and switches to palette storage automatically when the image has few enough colours.
If you want transparency in a lighter file that most browsers still show, choose WebP in the image converter instead.
Working copies for editing
PNG is a good format to edit in: you can save it again and again without adding compression artefacts. Convert the AVIF once, do the retouching or layering, and only pick a compact format for the final export.
Several files or whole folders can go in together, and each one reports its size before and after, with no account and no daily cap.
Questions
My browser cannot show AVIF. Will this work?
Yes. When the browser cannot decode the file, a WebAssembly AVIF decoder is loaded and used.
How many files can I convert?
There is no cap. Your browser works through them locally, several in parallel.
Can I get a JPG or WebP instead?
Yes. AVIF to JPG gives a smaller opaque file, and the image converter can write WebP, which keeps transparency at a fraction of the PNG size.
Are HDR images handled?
They are decoded to standard 8-bit colour, so they look like normal pictures but lose the extra brightness range.
