Convert AVIF to PNG
Convert AVIF images to PNG directly in your browser. Your files are never uploaded.
What to know
Going from lossy AVIF to lossless PNG cannot recover detail that was already thrown away, and the file usually gets larger rather than smaller. It is worth doing when you need transparency or intend to edit further, not to improve quality.
AVIF uses AV1 video compression for still images and is the most efficient common format, with transparency and wide colour support. Encoding is slow, so browsers can read it far more readily than they can write it.
PNG compresses losslessly and keeps full alpha transparency, which makes it the right choice for screenshots, logos and line art — and a poor one for photographs, where it produces far larger files than JPG.
Questions
Are my AVIF files uploaded anywhere?
No. The conversion runs inside your browser using the Canvas API. The file is read into memory on your own machine and never sent over the network, which you can confirm by opening your browser's developer tools and watching the network tab stay empty.
Does converting AVIF to PNG reduce quality?
PNG is lossless, so nothing is degraded during the conversion itself. Any quality already lost in the original AVIF cannot be restored, however.
Is there a file size limit?
There is no limit imposed by the tool, because there is no server to upload to. The practical ceiling is your device's available memory — very large images may be slow on an older phone.
