How do I convert PNG to WebP?

Drop the file on this page and press the button. 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 budget or an upload limit: a photograph in PNG is often five to ten times what it needs to be.

Is there anything odd about PNG?

A PNG of a screenshot should usually stay a PNG. A PNG of a photograph almost never should, and that distinction decides whether this conversion is a good idea.

Why WebP specifically?

WebP keeps transparency and is a fraction of the size, as long as whatever opens it is a browser.

Is the file uploaded?

No. The picture is decoded and re-encoded by the page. No request carries it anywhere, which the network panel will show you while it runs.
