URL Parser
Parse URLs into protocol, hostname, port, pathname, search params, and hash. Interactive URL builder to construct URLs from components. Free online URL parser tool.
Why Use a URL Parser?
Understanding URL structure is essential for web development, debugging, and API integration. A URL parser breaks down complex URLs into their individual components — protocol, hostname, port, path, query parameters, and hash — making it easy to inspect and modify each part independently. Our tool goes beyond parsing with an interactive URL builder that lets you construct URLs from scratch.
Key Features
- Parse any URL into protocol, hostname, port, pathname, search params, and hash
- Display each component in a separate field with individual copy buttons
- Interactive URL builder: modify components and rebuild the URL in real time
- Extract and list all query parameters as key-value pairs with copy support
- Validate URL format with clear error messages for invalid URLs
How It Works
- Paste or type a URL into the input field
- View the parsed components and query parameters instantly
- Switch to Build mode to modify individual components and query params
- Copy any component value or the entire rebuilt URL to clipboard
Technical Details
This tool uses the native JavaScript URL API (new URL()) for parsing, which follows the WHATWG URL Standard. It supports all standard URL components as defined by the URL specification. Query parameters are parsed using URLSearchParams for accurate decoding of encoded characters. The URL builder validates constructed URLs using the same API to ensure output correctness.
Frequently Asked Questions
Why does my URL show as invalid?
URLs must include a protocol (like https:// or http://) to be valid. The JavaScript URL parser requires a full protocol prefix. For example, use 'https://example.com' instead of just 'example.com'.
Can I add or remove query parameters in Build mode?
Yes! In Build mode, you can add new parameters with the 'Add Param' button, edit existing key-value pairs, or remove any parameter with the delete button. The URL is rebuilt in real time as you make changes.
What URL protocols are supported?
The parser supports all standard URL protocols including http, https, ftp, ws, and wss. You can select different protocols from the dropdown in Build mode.
