URL Parser

Parse URLs into individual components including protocol, host, path, and query parameters

URL Parser — Deconstruct Any URL into Its Component Parts: Protocol, Host, Port, Path, Query Parameters, Fragment, and Authentication Details

  1. Paste any URL into the input field — the tool immediately parses it using the browser's built-in URL constructor (which implements the WHATWG URL Standard). URLs can look deceptively simple but encode a rich structure: https://user:pass{'@'}api.example.com:8443/v2/users?page=2&limit=50&sort=name#results contains at least 8 distinct components, each with different security, routing, and data implications. The parser handles all valid URL schemes (http, https, ftp, ws, wss, file) and correctly processes internationalized domain names, IPv6 addresses, and percent-encoded characters.
  2. Review the automatically parsed components displayed in clearly labeled sections. Protocol (https:) — the scheme determining how the resource is accessed, critical for security context (https enforces TLS). Host and Hostname — the domain or IP address, with port number extracted separately if specified (:8443). Pathname (/v2/users) — the resource path on the server. Query String (?page=2&limit=50) — the raw search/query portion. Hash/Fragment (#results) — the client-side fragment identifier (never sent to the server). Origin (https://api.example.com:8443) — the security origin used for CORS and same-origin policy checks.
  3. Explore the decoded Query Parameters table — each parameter is extracted, URL-decoded, and displayed as a key-value pair. This is particularly valuable for debugging API calls, understanding tracking parameters in marketing URLs, or checking OAuth redirect URLs for correct parameter encoding. The parser also extracts authentication credentials if present in the URL (user:pass{'@'}) — note that embedding credentials in URLs is deprecated by modern browsers for security reasons. Use the URL Parser to: debug API integration issues, analyze competitor URL structures, validate redirect URL configurations, understand UTM tracking parameters in marketing campaigns, and check for proper URL encoding in webhook endpoints. All parsing runs locally using the browser's URL API — your URLs never leave your device.
