Free UTM generator and checker: build campaign URLs with utm_source, medium, campaign, term, and content—or parse an existing link. Browser-only.
No. UTM Builder runs in your browser. Nothing is uploaded to our servers for the core path. Keep using a private device when handling secrets.
Yes. Free to use without creating an account. Ads may appear outside the tool workspace according to site monetization rules.
Modern Chromium-based browsers and current Firefox/Safari builds work for most tools.
Clear the page when finished, avoid shared kiosks for secrets, and never paste production credentials into screenshots you share publicly.
After the page loads, most pure client tools continue to work without network calls.
A UTM generator appends standard campaign parameters so analytics tools can attribute traffic. This UTM builder creates clean URLs and can check/parse existing links.
utm_source, utm_medium, and utm_campaign are the common trio. Term and content are optional for paid search and A/B creative labels.
Paste a full URL into Check/parse to extract parameters, then rebuild with edits. That covers checker, converter, and calculator-style inspection workflows.
The tool uses the browser URL API to encode query values safely. Avoid putting raw spaces in campaign names when possible.
Open the result in a second app or tab, compare against a small known-good sample, and only then send it to clients or commit it to git. Copy outputs into your CMS or config carefully. Double-check production vs staging values and never paste live secrets into shared chats. If something looks wrong, adjust one setting at a time and rerun rather than stacking multiple weak exports.
Browser memory and CPU bound large jobs. Close unused tabs, try a smaller fixture first, then scale up. Desktop browsers are usually more reliable than phones for heavy media or WASM paths. After finishing, clear Downloads and the tool workspace when files contain personal or customer data.
Skip it as the sole system of record when you need multi-user collaboration, enterprise audit trails, or legally certified processing. Use your approved platform for those cases, and treat this page as a fast local assistant. Keep authoritative masters outside the browser session.
