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, vCards (contact info), and more. The most common use is encoding website URLs.

How much data can a QR code hold?

QR codes can store up to 7,089 numeric digits, 4,296 alphanumeric characters, or 2,953 bytes of binary data. More data results in a denser, harder-to-scan code.

Do QR codes expire?

Static QR codes (like those generated by this tool) never expire. The encoded data is permanent. Dynamic QR codes that redirect to URLs can be changed or deactivated by the service provider.

What size should I print my QR code?

For reliable scanning, print QR codes at least 2 × 2 cm (0.8 × 0.8 inches). Larger sizes are better for scanning from a distance. Ensure high contrast between the code and background.
