How can we help?
Short, practical answers about making, printing and managing your codes, and about your plan.
Getting started
Design and print
- File formats and sizes: which one to download
PNG and JPG for screens and documents. SVG, PDF and EPS for print, sharp at any size. Here is which file to pick and what to send a printer.
- Printing guide: size, contrast and quiet zone
How big to print a QR code, which colors scan best, why the light border matters, and how to test before a print run.
- Troubleshooting a code that will not scan
A checklist for codes that do not scan or open the wrong page, and what each message on the scanner's phone means.
Dynamic codes
- Change where a code points after printing
Edit the link, file or page behind a dynamic code from your dashboard. The printed code stays the same and opens the new content.
- Scan statistics explained
What we count as a scan, what each chart shows, how to export the numbers, and what we never store about the people who scan.
- Access rules: schedule, scan limit and password
Choose when a code starts and stops working, stop it after a number of scans, or ask for a password before it opens.
- Custom short links
Pick the words in your code's link, like qrdot.org/joes-pizza. Here are the rules, and why you choose it before printing.
- Link health alerts
We check the websites your codes point to and email you when one stops working, so a printed code never leads to an error page for long.
Plans and billing
- Plans and billing
The 7-day trial for $1.00, the 4-week, quarterly and annual plans, what they include, how you are charged and what shows on your card statement.
- How to cancel your subscription
Send the cancellation form or email support. We cancel and confirm by email, usually within one business day, and you are not charged again.
- What happens when a plan ends
Dynamic codes stop at the end of the paid period and show an inactive page. Your codes stay in your account, and subscribing again brings them back.
Account and support
- Your account and signing in
Sign in with a link sent to your email, no password needed. How the account is created, how long you stay signed in, and how to change it.
- Report a code that looks like a scam
Scanned a code that asks for a password, payment or personal details it should not? Report it. We review every report and block harmful codes.
