URL parser

About URL parser

URL Parser breaks any URL into its individual components — protocol, hostname, port, path, query parameters, and hash fragment — and displays each part clearly. Useful for debugging API endpoints, OAuth redirects, UTM links, and any complex URL during development.

When to use URL parser

• Extract and inspect query parameters from a complex redirect URL
• Debug API endpoint construction by separating path from query strings
• Parse OAuth callback URLs to extract authorization codes and state values
• Analyze UTM tracking parameters in marketing links
• Verify a URL is correctly formed before using it in code or configuration

How it works

Your input is passed to the browser's built-in URL constructor, which parses it according to the WHATWG URL Standard. Query parameters are extracted using URLSearchParams, producing a key-value listing. Invalid URLs trigger an "Invalid URL" error with a prompt to include the protocol — the most common omission.

Example

Parsed URL

Input:

https://nadhebe.com/tools/json-formatter/?mode=beautify&source=demo#workspace

Output:

Protocol: https:
Host: nadhebe.com
Path: /tools/json-formatter/
Query:
  mode: beautify
  source: demo
Hash: #workspace

Privacy & security

URL parser runs entirely in your browser. No input data is uploaded to any server, stored in a database, or shared with third parties. You can use it offline once the page has loaded.
