Is there a length limit?

QR codes support up to 2,953 bytes, but dense codes become harder to scan. Keep URLs short for best results.

Can QR codes contain tracking?

The QR code only encodes the URL you provide. If you want tracking, use a URL shortener — the QR itself stays the same.

Why does my WiFi QR code not connect?

Check the encryption type (WPA vs WEP vs nopass) and that the SSID/password are exact. iOS and Android handle hidden networks slightly differently.

About QR codes

QR codes store data in a 2D matrix of black and white modules. The error correction level determines how much of the code can be damaged while still being readable. Higher levels increase the code's density but improve resilience.

Text / URL

Plain text or any URL. Smartphones open URLs automatically.

WiFi

Uses the WIFI:T:...;S:...;P:...;; format. Scanning auto-connects on most phones.

vCard

Standard contact card format. Scanning prompts to add to contacts.
