UTM Campaign BuilderAnalytics-safe
Tag campaign URLs without corrupting your reports. Existing query parameters are preserved and casing is normalised, so one campaign stays one row.
The two mistakes that ruin campaign reports
Inconsistent casing. Facebook and facebook arrive in analytics as two separate sources, splitting one campaign across two rows that no report recombines. The lowercase switch is on by default for exactly this reason.
Losing existing parameters. Appending ?utm_source=… to a URL that already has a query string produces a broken link, and naive concatenation stacks a second utm_source onto a URL you edit twice. This builder merges into the URL's real search parameters, so rebuilding after an edit replaces the tags rather than duplicating them.
Frequently asked questions
What does UTM Campaign Builder do?
Build tagged campaign URLs that keep your analytics clean and consistent. The whole thing runs in your browser tab, so it is ready the moment the page finishes loading.
Is UTM Campaign Builder free to use?
Yes. UTM Campaign Builder is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
Do I need to create an account or sign up?
No. There is no account, no email address, and no login. Open UTM Campaign Builder, do the job, and take the result — nothing is gated behind a signup form.
Does UTM Campaign Builder send my data anywhere?
UTM Campaign Builder runs in your browser. Anything it can work out locally never leaves the tab; a check that has to reach a live site, a DNS server or a certificate has to send the address you asked about, and nothing about that is tied to an account — there is no account.
Does UTM Campaign Builder work on Mac, Windows, and phones?
Yes. UTM Campaign Builder runs in any modern web browser on Windows, macOS, Linux, Chromebook, Android, and iOS. There is nothing to download or install.
Can I use it as many times as I want?
Yes. There is no queue, no per-hour quota, and no counter that runs out — run UTM Campaign Builder as often as the work needs.
