UTM Link Builder
Build properly encoded campaign URLs while preserving existing query parameters and fragments.
Your data is processed locally in your browser whenever supported and is not uploaded to our servers.
How it works
Build a campaign URL in three steps
02
Describe the campaign
Enter the source, medium, campaign name, and optional term or content values.
03
Build and copy
Generate a correctly encoded link, review it, and copy it into your campaign.
Reliable URL handling
Tracking parameters without fragile string editing.
The builder uses the browser's native URL parser to encode campaign values, preserve unrelated parameters, and keep fragments in their correct position.
Five standard UTM fields
Add source, medium, campaign name, term, and content parameters.
Existing parameters preserved
Keeps non-UTM query parameters already present in the destination URL.
Old UTM values replaced
Updates duplicate or stale campaign parameters instead of appending conflicting copies.
Local link building
Formats the URL in your browser without visiting it or transmitting campaign details.
FAQ
Common questions
What are UTM parameters?
UTM parameters are query values added to a destination URL so analytics tools can attribute visits to a source, medium, campaign, keyword, or creative variation.
Which fields are required?
The destination URL, campaign source, campaign medium, and campaign name are required. Campaign term and campaign content are optional.
What happens to parameters already in my URL?
Non-UTM query parameters and the URL fragment are preserved. Existing UTM values are replaced with the form values, and blank optional fields remove stale term or content parameters.
Does this tool check whether the page exists?
No. It validates the URL structure but never visits the address or checks whether the destination is online.
Are campaign details uploaded?
No. The link is built locally in your browser, and Got A Tool does not receive or store the destination or campaign values.
