Break URLs into protocol, host, path, and query parameters.
URL Parser is a comprehensive URL analysis tool that breaks down any web address into its constituent parts. It extracts protocol, hostname, port, path, query parameters, and fragments, making it invaluable for web development, API debugging, and understanding URL structures. The tool supports relative URLs with a base URL option and automatically adds protocols when needed.
When building or testing REST APIs, use URL Parser to dissect endpoint URLs, verify query parameter structures, and understand how different URL components are interpreted by your application. It helps ensure your routing logic handles all URL edge cases correctly.
Parse tracking URLs to extract campaign parameters (utm_source, utm_medium, etc.), referrer information, and custom tracking data. This is essential for understanding traffic sources and analyzing marketing campaign effectiveness.
Examine URLs for potential security issues such as open redirects, malicious query parameters, or unexpected protocol schemes. URL Parser helps security professionals analyze suspicious links and identify phishing attempts by revealing the true destination and parameters.
Analyze URL structures for SEO optimization, ensuring clean paths, appropriate query parameters, and proper fragment identifiers. Parse canonical URLs, understand URL rewriting rules, and validate internal linking structures across your website.
When troubleshooting web applications, quickly parse URLs from browser address bars, log files, or error reports to understand exactly what resources were requested and what parameters were passed. This accelerates debugging of routing issues and parameter handling bugs.
Enter the complete URL you want to analyze into the URL field. You can paste URLs from your browser, API documentation, or log files. If you have a relative URL (like "/api/users?page=2"), enter the base URL in the optional Base URL field.
Click the Parse URL button to analyze the URL structure. The tool will automatically add "https://" if no protocol is specified, and it will resolve relative URLs against the provided base URL.
Examine the detailed breakdown showing origin, protocol, host, hostname, port, pathname, query string, fragment, and individual query parameters. Each component is clearly labeled and ready to copy for use in your code or documentation.
The "host" includes both the hostname and port (e.g., "example.com:8080"), while "hostname" is just the domain name without the port (e.g., "example.com"). If no port is specified, they will be the same.
When you provide a Base URL, relative URLs will be resolved against it. For example, if your base URL is "https://example.com/api/" and you parse "../users", it will resolve to "https://example.com/users". This is useful for testing relative links and API endpoints.
The tool will automatically prepend "https://" to URLs that do not have a protocol specified. This auto-applied protocol will be indicated in the results. If you need a different protocol (like http:// or ftp://), include it explicitly in your URL.
Query parameters are extracted from the URL and displayed both in the full query string (e.g., "?category=data&mode=inspect") and as individual key-value pairs separated by dots (e.g., "category=data · mode=inspect"). This makes it easy to see exactly what parameters are being passed.
Yes, the URL Parser automatically decodes URL-encoded characters (like %20 for spaces) and displays them in their human-readable form. The raw encoded values are preserved in the query string component for reference.
