Input URL / Query String

About URL Query Parameter Extractor & Analyzer

In web architecture and HTTP specifications (RFC 3986), the Query String is the portion of a URL assigned after the question mark (?) delimiter. Query strings contain key-value pairs formatted as key1=value1&key2=value2 used to pass state, search filters, pagination offsets, tracking parameters (UTM codes), and authentication tokens across web applications.

Why Extract & Visualize Query Parameters?

  • Marketing & Campaign Attribution: Inspect and decode complex UTM parameters (utm_source, utm_medium, utm_campaign) to audit analytics tags.
  • OAuth & API Debugging: Parse redirect callback URLs containing access tokens, state nonces, and authorization codes.
  • URL Sanitization: Quickly identify and strip unnecessary tracking parameters, click IDs (fbclid, gclid), and sensitive query tokens before sharing URLs.

Frequently Asked Questions (FAQ)

How does this tool handle duplicate query keys?

When multiple values share the same parameter key (e.g., filter=red&filter=blue), this tool parses and displays all values in an array format.

Does it automatically decode percent-encoded values?

Yes. All parameter values are decoded from percent-encoding into clean, readable text strings.
