URL Parser & Inspector

Parse any URL into its components: protocol, hostname, port, pathname, query string parameters, and fragment. Decode URL-encoded values, inspect query parameters in a table, and get the normalized form of the URL.

Examples:

How to Use URL Parser & Inspector

  1. 1Paste or type any URL into the input field.
  2. 2The URL is parsed into protocol, hostname, port, path, query string, and fragment.
  3. 3Query parameters are displayed in a table with decoded keys and values.
  4. 4Copy individual components or the normalized URL.

Frequently Asked Questions

What are the components of a URL?▾
A URL (Uniform Resource Locator) has these parts: (1) Protocol/Scheme: https:// or http:// or ftp://. (2) Username and password (optional): user:pass@. (3) Hostname: the domain or IP address. (4) Port: the TCP port (omitted if default — 443 for HTTPS, 80 for HTTP). (5) Pathname: the path to the resource after the domain. (6) Query string: key=value pairs after ? separated by &. (7) Fragment: the #anchor portion, not sent to the server.
What is URL encoding?▾
URL encoding (percent-encoding) converts special characters into a % followed by two hex digits. For example, a space becomes %20, a colon becomes %3A. This is necessary because URLs can only contain a limited set of ASCII characters. Query string values often contain encoded characters — decoding them reveals the actual value. The encodeURIComponent() JavaScript function URL-encodes a value; decodeURIComponent() decodes it.
What is the difference between the path and query string?▾
The path (/products/shoes) identifies the resource being requested and is part of the URL structure. The query string (?color=red&size=10) passes additional parameters to the server and appears after a ?. Both are sent to the server. The fragment (#section2) is NOT sent to the server — it is processed entirely by the browser and used for in-page navigation. Search engines typically ignore fragments (with some exceptions).
How do duplicate query parameters work?▾
URLs can have multiple values for the same key: ?tag=red&tag=blue. How these are handled depends on the server framework. PHP uses tag[] syntax, Express.js parses them into an array, and some servers take only the last value. The URLSearchParams API in JavaScript supports getAll("tag") to retrieve all values for a key. This tool shows all duplicate parameters in the table.
