What parts of a URL does it show?

It breaks the URL into protocol, username, password, hostname, port, origin, path, query string, individual query parameters and the #fragment.

Why does it say the URL is invalid?

The parser needs an absolute URL with a scheme. Add https:// (or another protocol) to the front so it can be parsed correctly.

Is my URL sent to a server?

No. The URL is parsed entirely in your browser using the built-in URL API, so nothing is uploaded.

URL Parser

Break a URL into protocol, host, port, path, query and hash.

Break a URL into its parts

Paste any absolute URL and see it split into every component — protocol, host, port, path, query string, decoded query parameters and fragment. It uses the browser’s native URL parser, so the breakdown matches exactly how browsers and servers interpret the address.

Great for debugging links, building integrations, or understanding a long tracking URL. Everything runs in your browser and nothing is uploaded.
