URL Parser & Query String Viewer
Parse and analyze URLs instantly. Extract protocol, host, port, pathname, and hash. View query parameters in a readable table with one-click copy. Perfect for debugging APIs, analyzing tracking links, or understanding complex URLs.
URL Parser breaks down any URL into its components for easy analysis. Enter a URL to instantly see the protocol, host, pathname, query parameters, and hash fragment. Query parameters are automatically decoded and displayed in a table with one-click copy for each value. Perfect for debugging API calls, analyzing tracking links, or understanding complex URLs. All parsing happens in your browser—your URLs are never sent to any server.

100% Client-Side Processing
All URL parsing happens directly in your browser using the native JavaScript URL API. Your URLs never leave your device. This tool works offline after the page loads.
How to Use the URL Parser
- Enter a URL in the input field. You can paste a full URL including protocol, or just the domain and path (https:// will be added automatically).
- View the breakdown of URL components: protocol, host, hostname, port, pathname, query string, and hash fragment.
- Examine query parameters in the table below the components. Keys and values are automatically URL-decoded for readability.
- Copy any value with a single click using the Copy button next to each component or parameter.
URL Components Explained
A URL (Uniform Resource Locator) consists of several parts that identify and locate a resource on the web:
| Component | Example | Description |
|---|---|---|
| Protocol | https: | The scheme indicating how to access the resource (http, https, ftp, etc.) |
| Host | example.com:8080 | The domain name and port combined |
| Hostname | example.com | The domain name without the port |
| Port | 8080 | The network port (empty for default: 80 for HTTP, 443 for HTTPS) |
| Pathname | /path/to/page | The path to the resource on the server |
| Query String | ?key=value&foo=bar | Parameters passed to the resource, starting with ? |
| Hash | #section | Fragment identifier for in-page navigation |

Frequently Asked Questions
What if my URL doesn't have a protocol?▼
If you enter a URL without a protocol (like "example.com/path"), the parser will automatically add "https://" to properly parse the URL. This is a common convenience for quickly analyzing URLs copied from various sources.
Why are some query parameter values shown differently?▼
Query parameters are URL-decoded for readability. If the original value was encoded (e.g., "hello%20world"), it will be displayed as "hello world" with the encoded version shown below. This makes it easier to read actual values while still seeing the original encoding if needed.
What are username and password in a URL?▼
URLs can contain authentication credentials in the format "protocol://username:password@host/path". This is commonly seen with FTP URLs or internal systems. Note that including credentials in URLs is generally discouraged for security reasons, as URLs may be logged or visible in browser history.
Why is the port empty for most URLs?▼
When using default ports (80 for HTTP, 443 for HTTPS), the port is typically omitted from the URL. The port field will only show a value when a non-default port is explicitly specified in the URL, like "example.com:8080".
Is my data safe when using this tool?▼
Yes, completely safe. All URL parsing happens directly in your browser using the built-in JavaScript URL API. Your URLs are never sent to any server. You can verify this by using browser developer tools to monitor network requests, or simply disconnect from the internet—the tool will continue to work.
