Free tools to build, check and clean up your campaign tracking
Three focused UTM tools that run entirely in your browser. Nothing you paste, upload or type is ever sent to a server.
UTM Builder
Build a single campaign-tagged URL — preserves existing parameters and never silently overwrites a conflict.
Build a URLBulk UTM Builder
Paste a spreadsheet or upload a CSV and generate UTM-tagged URLs for every row at once — one bad row never breaks the batch.
Process a CSVUTM Auditor
Check a URL or a whole batch for tracking problems — missing, duplicated or inconsistent parameters — and get a Tracking Health Score.
Audit your URLs100% private — every tool runs locally in your browser. URLs and CSV files are never uploaded anywhere.
