Developer & Text · URL Parser

Break a URL into its parts and decode the query string

Quick answer

Open Toolfox → URL Parser and paste a URL to see its scheme, host, port, path, query parameters and fragment, all decoded, as you type. It follows the WHATWG URL standard used by browsers, and nothing is fetched or looked up. It runs entirely on your computer (Mac, Windows or Linux). Files are never uploaded.
