FAQ
Q.Is my data sent to a server?
No. QR code generation runs entirely in your browser. No data ever leaves your device.
Q.What is error correction?
QR codes include redundant data that allows them to be read even if partially damaged or covered. Low (L) tolerates ~7% damage, Medium (M) ~15%, Quartile (Q) ~25%, High (H) ~30%.
Q.What size should I use?
256–512px works well for most digital use. For print, use 1024px or larger. The output is always a crisp PNG.
Q.Can I generate a WiFi QR code?
Yes — use the format: WIFI:S:<SSID>;T:<WPA|WEP|>;P:<password>;;
