Validation

What is a Valid URL?

A Uniform Resource Locator (URL) is a specific type of Uniform Resource Identifier (URI) that provides a means of locating a resource by describing its primary access mechanism (e.g. its network location).

A standard absolute URL follows the specification defined in RFC 3986: scheme:[//[user:password@]host[:port]][/path][?query][#fragment]

What does this tool do?

Pasting a URL into this validator runs a comprehensive series of checks and formats the details for easier debugging:

  1. Structural Verification: Evaluates compliance with browser URL standards.
  2. Protocol Analysis: Identifies the scheme (HTTPS, HTTP, FTP, mailto, file, etc.).
  3. Component Breakdown: Extracts username/password, hostname, port number, path, query string, and hash fragment.
  4. Query Parameter Inspector: Decodes and displays query parameters (e.g., UTM tracking codes, API parameters) in an interactive key-value table.
  5. Security Warnings: Flags suspicious features such as credentials in the URL (which are deprecated and insecure) or overly long query strings.
