How to create a QR code for a link or text
A QR code allows opening a link or reading information from a phone's camera. For it to work well, the content must be correct, and the code must retain sufficient contrast and size on the support where it will be published.
Prepare the content
If the QR contains a URL, open the link first and check that it's the final destination. Avoid shortened or redirected links that you don't control.
For text, use a brief string and check that it doesn't include private data you don't want to share with anyone who scans the code.
Test before publishing
Download the code and scan it with multiple devices if possible. Check that the destination opens correctly and that the QR remains legible in the final size.
If you're going to print it, leave a free margin around it and avoid placing elements on the code modules.
Common questions
Can a QR code open a web page?
Yes. If you encode a valid URL, the camera or reader can open the link when scanning it.
Can I change the link after downloading it?
No in a static QR code. To change the destination, you would need to generate another code or use a redirection service that you control.
