UTM Campaign URL Builder

How it works

The builder parses your website URL with the browser's URL API and attaches each filled-in field as a standard utm_source, utm_medium, utm_campaign, utm_term, or utm_content query parameter, rebuilding the link on every keystroke; saved links are appended to a running history kept in this browser's local storage, capped at 50 entries.

FAQ

Are the required fields (source, medium, campaign) actually enforced?

Not strictly — leaving one blank just omits that utm_ parameter from the resulting URL rather than blocking generation, so check the output before using a link with a required field left empty.

Where is my saved link history stored?

In this browser's local storage only, capped at the 50 most recent links — it isn't synced anywhere, so switching browsers or devices starts a fresh, empty history.
