AVIF keeps pictures small, but not every editor, email client or upload form can open it yet. PNG opens everywhere, keeps transparency, and is lossless, which makes it a safe format to edit, share or archive. Converting AVIF to PNG is the way to get an AVIF into a program that does not understand it.
Expect a much larger file: PNG does not compress photographs as efficiently as AVIF, so the PNG can be several times bigger. Converting also cannot bring back any detail the AVIF already discarded, because AVIF is lossy; the PNG simply stores the decoded pixels exactly. The result uses standard 8-bit colour, so a high-bit-depth or HDR AVIF is reduced to normal colour. Your browser reads the AVIF, which works in current versions of Chrome, Firefox, Safari and Edge.
There is no quality setting, because nothing more is lost. The pixel dimensions follow the original, each file keeps its name with only the extension swapped, and no metadata or watermark is added. Everything runs in your browser, so your images are never uploaded.
Tip: for photographs you only need to share, JPG or WebP gives a far smaller file than PNG.
No. PNG stores the pixels exactly as the AVIF decodes them, so nothing more is lost, but nothing is restored either.
AVIF is a very efficient lossy format and PNG is lossless. Photographs can be several times larger as PNG.
Yes. Transparent areas of the AVIF stay transparent in the PNG.
Your browser has to be able to read AVIF, which current versions of Chrome, Firefox, Safari and Edge can. In an older browser the file cannot be decoded and is skipped.
Yes. Add them all, convert once and download a single ZIP. Only the extension changes. A file named holiday.avif becomes holiday.png.
No. The conversion happens in your browser and the files never leave your device.
