URL Parser
Parse any URL into its individual components with our free online URL Parser. Paste a URL and instantly see its protocol, hostname, port, path, query parameters, and fragment - with both raw (encoded) and decoded values side by side. Each component includes a plain-English explanation. Perfect for debugging API calls, analyzing URL structures, verifying encoding, and learning how URLs work. The URL Parser also provides query parameter breakdowns and validation warnings about potential issues like HTTP usage or unusual ports. No signup required.

Features
Full URL Decomposition
Breaks any URL into protocol, hostname, port, path, query string, fragment, and authentication components. Every part is clearly labeled and explained.
Encoded vs Decoded Values
Shows both raw (encoded) and decoded values side by side. Automatically detects percent-encoded characters and decodes them for readability.
Query Parameter Breakdown
Parses all query parameters into a structured table with individual keys, values, and their decoded counterparts. Copy any parameter with one click.
URL Validation & Warnings
Detects common URL issues like HTTP vs HTTPS, localhost references, unusual ports, and encoded components. Helps you understand URL structure and security implications.
Use Cases
Debugging API Requests
When an API call fails, paste the URL into the parser to quickly check for malformed query parameters, incorrect encoding, or missing path segments.
Security Audits
Inspect URLs for exposed credentials in authentication parameters, check for HTTP vs HTTPS usage, and identify unusual ports or suspicious patterns.
Web Development
Understand how routing works by parsing complex URLs with fragments (single-page apps), query parameters, and encoded values during development and debugging.
SEO & Link Analysis
Analyze URL structures for SEO best practices - check for readable paths, proper parameter encoding, and canonical URL format compliance.
Learning & Education
A great teaching tool for students learning about URL structure. See how protocols, hostnames, ports, paths, and fragments all fit together in real URLs.
Data Extraction & Web Scraping
Parse URLs from scraped pages to extract query parameters, identify URL patterns, and understand the structure of the target website.
About URL Parser
What Is a URL?
A Uniform Resource Locator (URL) is the address used to access resources on the internet. A URL consists of several components: the protocol (scheme), hostname, port, path, query string, and fragment. Understanding each component helps developers debug issues, optimize SEO, and build better web applications. Our URL Parser breaks down any URL into all its constituent parts and shows both the raw encoded form and the human-readable decoded form.
How URL Parsing Works
The URL Parser uses the browser's built-in URL constructor to reliably decompose any valid URL into its components. Each component - protocol, hostname, port, path, query parameters, and fragment - is extracted and displayed with its raw value and decoded equivalent. Percent-encoded characters (like %20 for spaces, %2F for slashes) are automatically decoded so you can see the human-readable values. The parser also validates the URL structure and provides helpful warnings about potential issues.
Why Encoding Matters
URL encoding (percent-encoding) replaces unsafe ASCII characters with a % followed by two hexadecimal digits. For example, a space becomes %20 and a forward slash becomes %2F. This is essential because many characters have special meaning in URLs. The URL Parser shows both the encoded and decoded versions of every component, helping you understand how browsers interpret URLs and troubleshoot encoding-related issues in your applications.
Privacy & Security
All URL parsing happens entirely in your browser. No data is sent to any server. The URL you enter never leaves your device. This means you can safely parse sensitive URLs containing API keys, authentication tokens, or private endpoint paths without any risk of data exposure.

Frequently Asked Questions
A URL (Uniform Resource Locator) is the address used to access resources on the internet. Its components include: Protocol (e.g., https://), Hostname (e.g., example.com), Port (e.g., :443 or default), Path (e.g., /page), Query String (e.g., ?key=value), and Fragment (e.g., #section). Some URLs may also include authentication credentials (username:password@host). Understanding these components is essential for web development, debugging, and security analysis.
URL encoding, also known as percent-encoding, replaces unsafe or reserved characters in URLs with a % followed by two hexadecimal digits. For example, a space becomes %20, a forward slash becomes %2F, and a question mark becomes %3F. This is necessary because some characters have special meanings in URLs. Our parser shows both the raw (encoded) and decoded values for every component, helping you understand how your browser interprets the URL and troubleshoot encoding issues.
Query parameters appear after the ? in a URL and are typically formatted as key=value pairs separated by &. For example, in https://example.com/search?q=hello&page=2, the query parameters are q=hello and page=2. Our URL Parser automatically extracts each parameter, shows both the raw and decoded key/value, and displays them in a structured table. You can copy individual parameters or the entire URL with one click.
A URL (Uniform Resource Locator) is a type of URI (Uniform Resource Identifier) that provides both the identity and the location of a resource. While all URLs are URIs, not all URIs are URLs. A URI can identify a resource by name alone (a URN), while a URL always provides a way to locate and access it. In everyday web development, URL is the more commonly used term.
A fragment, also called a hash, appears at the end of a URL after the # character. Fragments are used by the client (browser) for navigation within a page - scrolling to a specific section, or for client-side routing in single-page applications. Fragments are never sent to the server in HTTP requests. Common uses include anchor links (#section-name) and SPA routing (#/dashboard/users).
Special characters in query parameters must be URL-encoded. Use encodeURIComponent() in JavaScript to encode parameter values. For example, a value like "hello world & more" becomes "hello%20world%20%26%20more". When building URLs programmatically, always encode parameter values to ensure they are transmitted correctly. Our parser helps you verify that your URLs are properly encoded by showing both forms.
The default port for HTTP is 80, and for HTTPS it is 443. When a URL uses the default port, it is typically omitted from the URL string (e.g., https://example.com uses port 443 implicitly). If a non-default port is specified, it appears after the hostname separated by a colon (e.g., https://example.com:8080). Our parser indicates whether the port is the default or explicit.
Yes! All URL parsing happens entirely within your browser using the built-in URL constructor. No data is sent to any server - the URL you enter never leaves your device. This makes it completely safe to parse sensitive URLs containing API keys, authentication tokens, private endpoints, or any other confidential information.
