How do I convert PNG to AVIF?

Drop the file on this page. It runs in your browser, so there is no upload, no account and no daily limit.

Why will my software not open a PNG file?

Nothing refuses a PNG. What refuses is a page weight budget or an upload limit, because a photograph stored as PNG is often five to ten times what it needs to be.

Why AVIF specifically?

AVIF is the smallest of them for a photograph and the slowest to write. It is worth it for a page you control and not for a file you are sending on.

Is the image uploaded?

No. It is decoded and re-encoded by the page, and no request carries it anywhere, which the network panel will show you.
