URL Parser & Query Decoder

Parse URLs locally, break down protocol, host, path, and query parameters, and copy extracted query values as JSON.

Click for theater mode

URLs are parsed only in your browser. Nothing is uploaded, logged, or sent to a third-party API.

How to Use

  1. Paste a complete URL, such as a link with UTM tags, tokens, pagination, or filters.
  2. Review the parsed protocol, host, path, search string, and hash below.
  3. Inspect each query parameter key and value in the table.
  4. Click "Copy Parameters JSON" to move the parsed query into debugging scripts, logs, or test fixtures.
  5. If the URL is missing a protocol or is severely malformed, the tool shows an error instead of guessing.

Core Features

  • Parse protocol, host, path, search, and hash as soon as you paste a complete URL
  • Display query string parameters as a clean key-value table while preserving repeated keys
  • Copy extracted URL parameters as a JSON object for debugging and test fixtures
  • Use browser-native URL and URLSearchParams APIs for realistic parsing behavior
  • Keep internal URLs, tokens, and user-specific links local to your browser

Calculation Logic

The tool uses the browser's built-in URL and URLSearchParams interfaces. That keeps parsing behavior close to frontend code, the address bar, and Web APIs instead of guessing URL structure with custom regular expressions.

If the same parameter name appears more than once, the exported JSON keeps those values as an array so multi-select filters, repeated tags, or tracking parameters are not lost. This tool is focused on structured parsing and parameter extraction, not URL character encoding.

FAQ

Are pasted URLs logged anywhere?

No. Parsing, table display, and JSON export run in your current browser session.

Can it handle malformed URLs?

The tool expects a complete URL, such as one starting with https://. Severely malformed input shows a clear error and is not sent to a server for processing.

What happens to repeated query parameters?

Repeated keys are exported as arrays in JSON and shown as separate rows in the table.

How is this different from a URL encoder?

A URL encoder converts characters for safe transport. A URL parser breaks a complete link into structured fields and query parameters.
