Frequently asked questions
Can I make a QR code for a URL?
Yes. Enter the complete URL, including https://, so scanners can recognize it as a web address.
Does the generated QR code expire?
No. It directly contains the input data and has no expiration, although the encoded destination can later change or disappear.
Why should I test the downloaded image?
Printing size, contrast, surrounding space and the amount of encoded data can all affect reliable scanning.
