URL Parser

Parse URLs into components and reconstruct from parts

Parse URL

Enter a complete URL to parse into components

What is URL Parsing?

URL parsing breaks down a web address into its individual components: protocol, hostname, port, path, query parameters, and hash fragments. This tool helps developers understand URL structure, debug routing issues, and construct URLs programmatically.

How to Use

  1. Parse URL: Enter a complete URL and click "Parse URL" to see all components
  2. Build URL: Fill in individual components and click "Build URL" to construct a complete URL
  3. Use the parsed components to understand URL structure or modify specific parts

Example

Input URL:

https://api.example.com:8443/v1/users?active=true&limit=10#results

Parsed components:

  • Protocol: https
  • Hostname: api.example.com
  • Port: 8443
  • Path: /v1/users
  • Query: ?active=true&limit=10
  • Hash: #results

Features

  • Parse complete URLs into individual components
  • Reconstruct URLs from components
  • Handle international domain names (punycode)
  • Support URLs with authentication credentials
  • Automatic protocol defaulting (defaults to HTTPS)
  • Smart default port handling (omits 80 for HTTP, 443 for HTTPS)
  • 100% client-side processing for privacy

Common Use Cases

  • Debug API endpoint URLs
  • Extract query parameters from URLs
  • Construct URLs programmatically
  • Validate URL structure
  • Analyze redirect chains
  • Parse URLs from logs or configuration files

Frequently Asked Questions

What is a URL parser?

A URL parser breaks down a web address into its individual components like protocol (http/https), hostname, port, path, query parameters, and hash fragments. This helps developers understand URL structure, debug routing issues, and construct URLs programmatically.

What components can this tool extract?

The parser extracts protocol, hostname, port, pathname, query string, hash fragment, username, password, origin, and the complete href. It handles all standard URL formats including those with authentication, custom ports, and international domain names.

Can I rebuild a URL from components?

Yes, the tool supports URL reconstruction. After parsing, you can modify individual components and rebuild the URL. The builder automatically handles default ports (80 for HTTP, 443 for HTTPS) and ensures proper formatting.

Does it handle URLs without a protocol?

Yes, if you enter a URL without a protocol (like 'example.com'), the parser automatically defaults to HTTPS. This matches modern browser behavior and ensures the URL is properly formatted.

What about international domain names?

The parser supports international domain names (IDN) in their punycode format (like xn--e1afmkfd.xn--p1ai). It correctly extracts all components from these domains just like standard ASCII domains.

Is my data sent to a server?

No, all URL parsing happens in your browser. Your URLs never leave your device, ensuring complete privacy for sensitive URLs that might contain authentication tokens or internal network addresses.

Can I parse localhost and IP addresses?

Yes, the parser handles localhost URLs and IP addresses (both IPv4 and IPv6). This is useful for testing local development servers or working with internal network addresses.
