QR code generator with UTM
A QR code that shows up
in your analytics.
Build a tracked link and its QR code in one step, so scans from print and posters show up in your analytics.
Your tracked link
Your QR code
Free, no account, nothing leaves your browser.
How to use it
- 1Enter the page and the UTM tags
Put in the full address you want people to land on, then source (for example flyer), medium (qr) and campaign (spring-launch). Term and content are optional. Leave the UTM box off to make a plain QR code for the URL.
- 2Check the tracked link and the code
The tagged URL and the QR code update as you type. The code contains exactly the URL shown above it, so what you see is what a phone will open.
- 3Download it, then scan it before you print
Download a PNG or SVG. Test the printed or on-screen code with at least two phones and make sure the tagged URL opens the right page. Keep the white border and print it large enough to scan.
Questions
Why add UTM parameters to a QR code?
A QR code only holds a link, and a visit from a scan looks like direct traffic in analytics unless the link says otherwise. UTM tags in the link let Google Analytics and similar tools report those visits under the source, medium and campaign you chose, for example flyer, qr and spring-launch.
Does the QR code count scans for me?
No. This is a static QR code: it holds the URL itself, with no redirect in between, so nothing counts scans. What you can measure is the visits that reach your site with your UTM tags, in your analytics. That also means the code never expires and never depends on this site.
Which UTM parameters are required?
Google Analytics 4 documents utm_source, utm_medium and utm_campaign as the core three; utm_term and utm_content are optional. Values are case sensitive ("QR" and "qr" are two mediums), so keep them lowercase. The tool can lowercase them for you.
Which error correction level should I pick?
Error correction lets a code still scan when part of it is dirty or covered. L recovers about 7% of the code, M about 15%, Q about 25% and H about 30%, under the QR standard. Higher levels make the code denser, which is harder to scan at small sizes. M is a sensible default; use Q or H only if you plan to put a logo over it, and test it.
How big should I print it?
As a rule of thumb, scanners need each dot to be a few printed millimetres at reading distance, and a long URL makes the dots smaller. Keep the URL short, keep the white quiet border, use dark dots on a light background and test the real print. This tool warns when the URL is long enough to make a dense code.
Can I change the colours?
Yes, but keep strong contrast: dark dots on a light background. Many scanners cannot read light dots on a dark background (an inverted code), and pale colours fail in poor light. The tool warns on low contrast or an inverted pair; it cannot test every phone, so scan your final code.
Is the QR code correct?
The encoder follows the QR Code Model 2 specification for byte-mode text (versions 1 to 40, four error correction levels, the eight masks) and was checked by decoding generated codes with an independent QR reader. Even so, always scan the final code yourself before you print it.
Does this tool keep my URLs?
No. The URL, the tags and the code are built in your browser. Nothing is sent or stored. Do not put personal data in a UTM value: the tags are visible to anyone who scans the code.
Should I use UTM tags on links inside my own site?
No. Tagging internal links can overwrite the original source of a visit. Use them on links that bring people in from outside: print, posters, packaging, email, social posts and ads.
