What Is a URL Parser?
A URL (Uniform Resource Locator) Parser is a tool that breaks down a URL into its individual components as defined by the URL specification. Every URL consists of several parts: the protocol (e.g., https:), hostname (e.g., example.com), optional port number, pathname (e.g., /api/users), query string (key-value parameters after ?), and hash fragment (the part after #). This tool uses the browser's built-in URL API to accurately parse any valid URL and display each component separately, including a structured breakdown of query string parameters into individual key-value pairs.
How to Use the URL Parser
- 1Paste or type a complete URL into the input field. A sample URL is provided to demonstrate the tool's capabilities.
- 2The tool instantly parses the URL and displays each component: protocol, hostname, port, pathname, search, hash, and origin.
- 3Query parameters are extracted and shown in a structured key-value table below the URL components.
- 4If the URL is invalid, an error message is displayed. Check for missing protocol (http:// or https://) or malformed syntax.
- 5Use this tool to verify URLs before using them in code, API configurations, or redirect setups.
Common Use Cases
API Endpoint Analysis
Break down complex API URLs to understand the endpoint structure, extract query parameters, and verify correct path formatting.
Redirect Debugging
Parse redirect URLs from OAuth flows, SSO systems, or marketing campaigns to verify that all parameters are correctly included.
Deep Link Inspection
Analyze deep links and app URLs to verify that the scheme, host, path, and parameters are correctly formatted for mobile apps.
Web Scraping & Automation
Extract and understand URL patterns from websites to build correct URL templates for web scraping or automated testing.
Frequently asked questions
What happens if I enter a URL without a protocol?
The URL API requires a protocol to parse correctly. URLs without a protocol (like 'example.com/path') will show as invalid. Add 'https://' to parse them correctly.
How are duplicate query parameters handled?
The tool lists all query parameters in order, including duplicates. If a URL has '?tag=a&tag=b', both entries will be shown separately, matching how the URLSearchParams API handles them.
What is the difference between pathname and search?
The pathname is the path portion of the URL before the question mark (e.g., '/api/users'). The search is everything from the question mark to the hash, including the '?' itself (e.g., '?page=1&limit=10'). Together they form the full request path.
Does this tool support non-HTTP URLs?
Yes. The URL parser works with any valid URL scheme including ftp://, ws:// (WebSocket), file://, and custom schemes like myapp://. The parsing follows the same URL specification rules regardless of the protocol.
