How to use it

  1. Choose UTM builder, URL inspection, or component encoding.
  2. Enter a URL or text, plus any campaign parameters.
  3. Copy the output or download it as a file.

Good to know

Only HTTP and HTTPS URLs are accepted for building and inspection. URLs are parsed locally; no destination is fetched. Existing non-UTM parameters and fragments are retained.

The UTM builder replaces the five standard UTM fields. Component decoding preserves literal plus signs; URL query inspection interprets them as spaces. Repeated query parameters remain separate.
