Frequently Asked Questions
What can I encode in a QR code?
QR codes can encode URLs, plain text, email addresses, phone numbers, SMS messages, WiFi credentials, vCard contacts, calendar events, and more.
What size should my QR code be?
The minimum recommended size depends on scanning distance. For print materials scanned at arm length, at least 2cm x 2cm. For posters or signage, scale up proportionally to the viewing distance.
Can I customize the QR code colors?
Yes, but ensure high contrast between the code and background. Dark codes on light backgrounds work best. Avoid low contrast combinations that may not scan reliably.
Do QR codes expire?
Static QR codes (like those generated here) never expire. The code itself is just encoded data. However, if you encode a URL, the destination website could change or go offline.
