URL Structure

A URL can contain up to 8 components. Here's how they map to the sample URL. The full grammar is defined in the <a href="https://url.spec.whatwg.org/#concept-url" target="_blank" rel="noopener">WHATWG URL Living Standard</a>:

What Is a URL Parser?

Debugging a webhook, tracing a redirect chain, or just trying to figure out what query parameters are actually being sent? A URL parser breaks the URL into its building blocks — protocol, hostname, port, path, query string, and fragment — so you can see exactly what is going on. This tool follows the structure defined in RFC 3986 and uses the browser's built-in URL API to handle edge cases like IPv6 addresses, IDN hostnames, and percent-encoded characters. Query parameters are decoded using URLSearchParams. Everything runs in your browser — nothing leaves your machine.

How to Use the URL Parser

Paste a URL

Copy any URL — from a browser address bar, an API endpoint, or a log file — and paste it into the input field.

Inspect the Parsed Components

The tool instantly breaks the URL into its parts: protocol, hostname, port, path, query parameters, and fragment. Each component is labeled clearly.

Use the Extracted Data

Copy individual components to use in your code, debugging, or documentation. The parsed query parameters are especially useful for API integration work.

Parsing Example

Example: Parsing an API URL

Input URL:

https://api.example.com:8080/v2/users?page=2&limit=50&sort=desc#results

Parsed components:

Protocol:  https:
Hostname:  api.example.com
Port:      8080
Path:      /v2/users
Query:     page=2 | limit=50 | sort=desc
Fragment:  results

Frequently Asked Questions

Why does it require https:// or http://?

The browser's URL API requires a scheme to determine how to parse the rest. Without https:// or another scheme, the input is treated as a relative URL with no base, which fails. Prepend https:// if you only have a hostname. You can browse all officially registered schemes in the IANA URI schemes registry.

Are query parameter values decoded?

Yes. The Query Parameters table shows decoded values. For example, q=hello+world shows hello world. The raw encoded query string is also shown in the Structure section. The original URL specification covering query string syntax is RFC 1738.

Can I build a URL from scratch?

Use the Query String Builder to construct query strings from key-value pairs and get a complete URL.
