Frequently Asked Questions
What is error correction level?+
QR codes include redundant data so they can still scan even if partially damaged or obscured. L (~7%) suits clean digital displays; M (~15%) is the safe default; Q (~25%) tolerates minor damage; H (~30%) is best for printed codes that may get scratched.
Why does my WiFi QR code not connect?+
Most phones expect the security type as "WPA" (covers WPA2/WPA3 too). Make sure the SSID and password are exact — including case. For open networks, choose "None".
Can I customize the QR code colors?+
Yes — but keep enough contrast between foreground and background. Light-on-dark works as long as the contrast ratio stays high; otherwise scanners will fail.
Are these QR codes free to use commercially?+
Yes. QR codes generated through this tool can be used in marketing, packaging, business cards, or any commercial context with no licensing fees.
