URL Parser & Query String Analyzer
Note: This tool uses the browser's native URL API to parse URLs. It requires a valid URL with a protocol (e.g., http://, https://). All parsing happens locally in your browser for complete privacy.
About URL Parser
A URL (Uniform Resource Locator) is the address of a resource on the internet. Understanding URL structure is essential for web development, debugging, and API integration. This tool breaks down URLs into their component parts, making it easy to see protocol, host, path, query parameters, and fragments. It uses the browser's native URL API for accurate parsing and displays results in an easy-to-read format. Perfect for debugging URLs, analyzing query strings, understanding URL structure, or extracting specific URL components. All parsing happens in your browser, ensuring complete privacy.
How to Use
- Paste or type a URL into the input field.
- The tool will automatically parse the URL as you type.
- Click "Parse URL" to manually trigger parsing.
- View all URL components in the detailed table.
- Click the copy icon next to any component to copy it to your clipboard.
- If the URL has query parameters, they'll be displayed in a separate table below.
- Click "Load Example" to see a sample URL with various components.
- Use "Clear" to reset all fields and start over.
Frequently Asked Questions
What is a URL?
A URL (Uniform Resource Locator) is the address of a resource on the internet. It consists of several parts: protocol (http/https), host (domain name), port (optional), path, query string (parameters), and hash (fragment). Understanding these components is crucial for web development and debugging.
What are URL components?
URL components include: Protocol (http://, https://), Host (www.example.com), Port (:8080, optional), Pathname (/path/to/page), Search/Query string (?key=value), Hash/Fragment (#section), and Origin (protocol + host + port). Each component serves a specific purpose in identifying and accessing web resources.
What are query parameters?
Query parameters (or query strings) are key-value pairs appended to a URL after a question mark (?). They pass data to web servers, such as search terms, filters, or tracking information. Multiple parameters are separated by ampersands (&). Example: ?name=John&age=30
Why does my URL show an error?
The URL must include a protocol (http:// or https://) to be valid. Common errors include missing protocols, invalid characters, or malformed URLs. Make sure your URL follows the standard format: protocol://host/path?query#fragment
What's the difference between host and hostname?
Host includes the hostname and port (example.com:8080), while hostname is just the domain name without the port (example.com). If no port is specified, they're the same. Most websites use default ports (80 for HTTP, 443 for HTTPS) which aren't shown in the URL.
What is the hash/fragment?
The hash or fragment (starting with #) identifies a specific section within a page. It's not sent to the server but used by the browser to navigate to specific content. Common uses include linking to page sections, single-page application routing, and tracking.
Can I parse relative URLs?
No, this tool requires absolute URLs with a protocol. Relative URLs (like /path/to/page or ../page.html) don't contain enough information to be parsed by the URL API. They need to be resolved against a base URL first.
Is my data secure?
Yes! All URL parsing happens entirely in your browser using the native URL API. Your URLs are never sent to any server, ensuring complete privacy. The tool works offline once loaded, and no data is collected or stored.
Can I decode URL-encoded characters?
The URL API automatically decodes percent-encoded characters in query parameter values. However, it preserves encoding in the raw query string. If you need to decode the entire URL string, use a URL decoder tool.
