What is the UTM parameter editor?
A free, browser-based tool for inspecting and editing the query parameters of an existing URL. Paste a link and every parameter after the ? — including utm_source, utm_medium and any others — becomes an editable row you can change, add or remove. The rewritten URL is rebuilt live. Everything runs in your browser, so nothing you paste is uploaded.
How to use it
- Paste a URL into the box on the left.
- Edit, add or remove parameter rows as needed.
- Copy the rewritten URL from the right.
Common use cases
- Fixing a typo in a UTM value without rebuilding the whole URL.
- Inspecting which tracking params a shared link already carries.
- Adjusting a campaign URL for a new channel.
