UTM Link Builder

Create a campaign URL with encoded UTM parameters while keeping other query values and the page fragment.

Enter your input

Use plain-text campaign values, up to 2,000 characters each. Maximum URL length: 50,000 characters.

Your input is processed in your browser and is not uploaded to ToolPixels. This tool does not save it.

Tag a campaign link

Enter an HTTP or HTTPS destination, then a source, medium and campaign name. For example, use newsletter as the source and email as the medium. Enter plain text, not already encoded values. Build, review and copy the link.

The five lowercase utm_ fields shown here replace existing values of the same name, including duplicates. Blank optional fields remove existing utm_term or utm_content values. Other parameters and the fragment remain. Query serialization may normalize encoding, with spaces written as +. Leading and trailing field whitespace is removed. Links are not shortened, visited or tracked by this tool; your destination analytics must support UTM reporting. Do not put sensitive personal information in campaign values.
