URL Parser
Inspect and decompose URLs into protocol, hostname, path, query parameters, and fragment.
About This Tool
The URL Parser & Inspector decomposes any URL into its individual components: protocol, hostname, port, pathname, query string, and fragment. It also extracts and displays all query parameters as a key/value table for easy inspection.
Parsing uses the browser's native URL API, which follows the WHATWG URL Standard. URL structure: protocol://hostname:port/pathname?search#hash. Query parameters are key=value pairs separated by &. The port defaults to 80 (http) or 443 (https) if omitted. All processing runs locally — no data is sent to any server.
How to Use
- Paste a URL into the input field, or click Sample to load an example.
- Click Parse (or press Enter) to decompose the URL.
- Review each component in the breakdown table.
- Click Copy next to any component to copy it to your clipboard.
Use Cases
Frontend developers debug complex URLs with many query parameters by reading each one individually. Backend developers validate URL structures in API testing. QA engineers copy URL components for test scripts. Marketers inspect tracking parameters (utm_source, utm_medium) in campaign URLs.
FAQ
- Do I need to include http:// in the URL? — The tool auto-prepends https:// if no protocol is detected. For best accuracy, include the full URL.
- Are URL-encoded query parameters decoded? — Yes. The URLSearchParams API automatically decodes percent-encoded values (e.g., %20 becomes a space).
- What is the fragment (#)? — The fragment (hash) identifies a section within the page. It is never sent to the server — it is processed only by the browser.
