UTMora

Free, private, deterministic

UTM Builder

Add campaign parameters without hand-editing a query string. UTMora keeps unrelated parameters, replaces old UTM values, and consistently encodes the result.

Your correctly encoded campaign URL will appear here as you type.

Existing UTM tags are replaced. Other query parameters stay in their original order.

What happens

One predictable URL rule.

Existing links are safe to paste

Non-UTM query parameters stay in place, including repeated parameters. Existing UTM tags are removed case-insensitively and replaced once in a canonical order.

Values are encoded as values

Spaces, symbols, and Unicode text use standard URL encoding. UTMora never visits, redirects, shortens, or measures the destination.
