FAQ

What to do if the generated QR code cannot be scanned?

1) Use a URL shortener if content is too long; 2) size at least 256px; 3) sufficient foreground/background contrast; 4) use Q or H error correction with Logo; 5) use SVG vector format for printing. See full FAQ.

WiFi QR code won't connect?

Verify SSID case and encryption type; some older Android devices don't support WEP; enable "Hidden network" for hidden SSIDs. iOS 11+ and most Android 10+ natively support. Use the system camera, not WeChat. See WiFi QR page.

Is my data uploaded?

No. All generation and scanning happen locally in your browser. No data is uploaded to any server. No registration, completely free.

How to choose error correction level?

L=7%, M=15%, Q=25%, H=30%. Use L or M for plain text; Q or H with Logo; H for printed materials. QRCode.wang auto-switches to H when you upload a Logo. See error correction guide.
