How do I convert JPG 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 JPG file?

Nothing refuses a JPG. What wants something else is a page that needs to be smaller, or a design that needs the transparency JPG has never had.

Is there anything odd about JPG?

A JPG has already thrown information away. Converting it to a better format keeps what survived and makes the file smaller; it does not undo the first encode, and nothing can.

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.
