URL Parser & Inspector

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. Each component can be individually copied to the clipboard.

Parsing uses the browser's native URL API, which follows the WHATWG URL Standard. All processing runs locally — no URL data is sent to any server.

How to Use

1. Paste a URL into the input field, or click Sample to load an example.
2. Click Parse (or press Enter) to decompose the URL.
3. Review each component in the breakdown table.
4. Click Copy next to any component to copy it to your clipboard.

URL Component Reference

Structure: protocol://hostname:port/pathname?search#hash. Protocol: http:, https:, ftp:, etc. Hostname: domain name or IP address. Port: defaults to 80 (http) or 443 (https) if omitted. Pathname: path after the domain. Search: query string starting with ?. Hash: fragment identifier starting with #. Query parameters are key=value pairs separated by &.

Use Cases

Frontend developers debug complex URLs with many query parameters by extracting and reading each parameter individually. Backend developers validate URL structures in API testing. QA engineers copy specific URL components for test scripts. Marketers inspect tracking parameters (utm_source, utm_medium) in campaign URLs. Security researchers analyze suspicious URLs to identify potentially malicious components.

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 → 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.
