Frequently Asked Questions
What data can I encode in a QR code?
QR codes can store URLs, plain text, email addresses, phone numbers, WiFi credentials, vCard contacts, and more. The maximum capacity is about 3,000 characters for alphanumeric data.
What size should my QR code be?
For print, aim for at least 2cm × 2cm (about 300px at 300 DPI). For screens, 200–400px is typically sufficient. The default 300px works well for most use cases.
Can QR codes expire?
Static QR codes (like those generated here) never expire. The data is encoded directly in the pattern and remains scannable indefinitely.
Are QR codes free to use?
Yes. QR code technology is open and free. There are no licensing fees for creating or scanning QR codes.
