URL Parser — Free Online Tool

What Is URL Parser?

A free online URL parser. Paste any URL to instantly see its components: protocol, hostname, port, path, query string, and hash. Query parameters are displayed as editable key-value pairs with copy buttons.

URLs are more complex than they appear at first glance. A single URL contains protocol, hostname, port, path, query parameters, and fragment — each serving a distinct purpose. URL Parser breaks any URL into its individual components and displays them in a structured format, making it easy to inspect, debug, and extract specific parts.

Paste any URL into the input field and the parser immediately displays all components: protocol (https or http), hostname (domain name), port (if specified), path (the route after the domain), query string (everything after ?), and hash (everything after #, also called fragment). Query parameters are shown as an editable key-value table, making it easy to see what parameters are being passed and copy individual values.

The structured breakdown is invaluable for web development and API debugging. When an API call fails, you can paste the URL into the parser to verify the endpoint path, check query parameter formatting, and spot encoding issues. When analyzing tracking URLs, the query parameter table shows all UTM parameters and other tracking values in a readable format.

Each component can be copied individually, which is useful when you only need one part of a URL — for example, extracting just the hostname for a configuration file, or copying the query parameters for a redirect implementation. The parsing uses the browser's built-in URL constructor, ensuring standards-compliant decomposition.

Real-World Use Cases for URL Parser

Debugging a Broken API Endpoint URL

Your API call to "https://api.example.com/v2/users?status=active&limit=50" is failing. Paste it into the parser. The hostname is api.example.com, the path is /v2/users, and the query parameters are status=active and limit=50. Notice the path uses v2 — check if the API was updated to v3.

Extracting Tracking Parameters from a Marketing URL

A marketing link is "https://shop.example.com/products?id=123&utm_source=newsletter&utm_medium=email&utm_campaign=summer_sale". Paste it into the parser. The query parameter table shows all UTM parameters clearly. Copy individual values for your campaign tracking spreadsheet.

Analyzing a URL with Hash Fragment Routing

A Single Page Application uses hash-based routing: "https://app.example.com/#/dashboard/users/42". The parser shows the path as / and the hash as /dashboard/users/42. This makes it clear the SPA is using the hash for client-side routing, not server-side path resolution.

Pro Tips for URL Parser

1Use the URL parser to verify that query parameters are correctly URL-encoded. If a parameter value contains & or =, it should be encoded to %26 or %3D to prevent parameter splitting.
2The hash (fragment) portion of a URL is not sent to the server — it is handled entirely by the browser. This is why SPAs use hash-based routing.
3When a URL contains a port number (e.g., https://localhost:3000), the parser shows it separately. Most standard ports (80 for HTTP, 443 for HTTPS) are omitted from visible URLs.
4The URL constructor used for parsing follows the WHATWG URL standard, which is the same standard used by modern browsers and Node.js.

URL Parser — Frequently Asked Questions

What are the parts of a URL?

A URL has: protocol (https://), hostname (example.com), port (:8080), path (/page), query (?key=value), and fragment (#section). Example: https://example.com:8080/path?key=value#section

What is a query parameter?

Query parameters are key-value pairs after the ? in a URL. They are separated by &. Example: ?name=hello&age=25 has two parameters: name=hello and age=25.

Can I use these tools with sensitive/proprietary data?

Absolutely. All processing runs locally in your browser with zero server uploads. This makes these tools safe for proprietary code, internal API keys, and confidential data.

Do these tools work offline?

Yes, once the page has loaded, most developer tools continue functioning without an internet connection. This makes them ideal for air-gapped environments or travel.

What browsers are supported?

All modern browsers are supported: Chrome, Firefox, Safari, and Edge. Internet Explorer is not supported. The tools leverage modern JavaScript APIs like Web Crypto, TextEncoder, and BigInt.
