UTM link builder.
Build tidy, trackable links for your campaigns. Required fields are validated to the GA convention — lowercase, no spaces — so your analytics reports stay clean.
Frequently asked questions
What are UTM parameters?
UTM parameters are five query-string tags (utm_source, utm_medium, utm_campaign, utm_term, utm_content) that analytics platforms like Google Analytics use to attribute a visit to a specific marketing touchpoint.
Do you store the UTM links I build?
No. The builder runs entirely in your browser and the server. We never store your destination URLs or campaign names. Recent links are kept only in your own browser's localStorage.
Why do the fields require lowercase?
Analytics platforms treat 'Newsletter' and 'newsletter' as two different sources, so mixing cases fragments your reports. Shrtr enforces lowercase-only to keep your data clean across teammates.
Can I shorten the built URL?
Yes. After building, click 'Shorten this' to send the URL to the Shrtr shortener with one click. You'll get a short link plus a QR code.
