❓ Frequently Asked Questions

What can I encode in a QR code?
URLs, plain text, contact info (vCard), WiFi credentials, phone numbers, email addresses, and more. The content limit depends on error correction level.
What is error correction level?
Error correction allows QR codes to be read even if partially damaged. L=7%, M=15%, Q=25%, H=30% of data can be recovered. Higher levels make bigger codes but more reliable.
Can I scan QR codes from screenshots?
Yes! Upload any image containing a QR code or paste directly from clipboard using Ctrl+V (Windows) or Cmd+V (Mac).
