About this utm link builder
Add campaign tags to an HTTP or HTTPS address without manually escaping each value. Enter the destination, source, medium, and campaign name; term and content are optional. The builder keeps unrelated query parameters and the fragment while replacing existing standard UTM fields. Copy the finished address into your campaign workflow. No address is opened or submitted, and the builder does not connect to an analytics provider.
How the utm link builder works
The URL API validates the address and URLSearchParams serializes five standard UTM parameters. Blank optional fields remove their existing values.
