Paste a full URL and the tool splits it into every component — protocol, host, port, pathname, search, individual query params, hash and origin — in a clear table.
The origin is the scheme, host and port combined, e.g. https://example.com:8080 — it defines the security boundary for browsers.
When no port is specified the browser uses the scheme's default (80 for http, 443 for https), so the explicit port is empty.
Yes — each key/value pair is extracted and percent-decoded so you can read the actual values behind %20 and similar escapes.
