How do I convert AVIF to PNG and keep transparency?

Drop the .avif file onto filetity's AVIF to PNG converter and the image is decoded and re-encoded in your browser, then saved back to your device. PNG is the right target when the image has a transparent background, because PNG keeps transparency and JPG fills it in. AVIF is a newer format that many older apps and editors cannot open yet, which is normally why it needs converting at all. Nothing is uploaded, there is no account, and the output has no watermark. PNG is lossless, so the converted file is often larger than the AVIF it came from, sometimes several times larger.

When you would use this

Situations, not settings.

An AVIF that your editor will not open
The format is newer than a lot of desktop software, which simply reports an unknown file.
An image saved from a modern website
More sites now serve AVIF, so the file you saved is in a format your other tools may not read yet.
Something going into an old workflow
PNG is lossless, so nothing is given up in the move.

How it works / no cloud

A conversion engine, not an upload form.

filetity decodes the AVIF with the browser's own decoder, which every current browser ships, and re-encodes it as PNG. That is why this needs no multi-megabyte codec download the way HEIC does.

Straight answers

No accordion. Nothing hidden.

Is it free?
Yes, with no watermark and no page limit.
Does it need an account?
No. There is no account system.
Is my file processed on my device?
Yes. The file is read by your browser and never uploaded. There is no server to send it to.
What formats are supported?
AVIF in. PNG out, one file per image, or a ZIP when you convert several.
What are the limits?
No image count limit. Needs a browser from 2021 or later, which is when AVIF decoding became standard.
Does it work on mobile?
Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
Does it work offline?
Yes, after you have used it once. Your browser keeps what the tool needs, so it then works with no network connection.
Why will nothing on my computer open an AVIF?
AVIF is recent, and support arrived in browsers years before it arrived in desktop editors and older phones. The image is fine; the program looking at it has not caught up. PNG is the safest format to hand those programs.
Will the PNG be much larger?
Yes, usually several times larger. AVIF is a modern lossy format and PNG is lossless, so it stores every pixel exactly. That is the trade you are making to get a file everything can open.
Does this need a plugin or a codec download?
No. Your browser already decodes AVIF, so this page uses that. Nothing is downloaded to make it work and nothing is uploaded to a server.
Is transparency preserved?
Yes. AVIF supports an alpha channel and so does PNG, so transparent areas come through unchanged.
What happens to an AVIF that holds an image sequence?
You get a still of its first frame. AVIF is built on a video codec and can carry a sequence, PNG holds one image, and there is no frame handling in this path, so the rest is dropped. Rare, but it is not something the file will tell you afterwards.
Can I convert several AVIF files together?
Yes. Drop them all; each becomes a PNG and they download as one ZIP.
