Question 1

What size should my QR code be?

Accepted Answer

For print, use at least 2×2 cm (0.8×0.8 in). For screens, 256px or larger works well. Larger codes scan more reliably at a distance.

Question 2

Why won't my QR code scan?

Accepted Answer

Low contrast between foreground and background is the most common issue. Use a dark foreground on a light background, or vice versa.

Question 3

Can I create a WiFi QR code?

Accepted Answer

Yes. Select the WiFi type, enter your network name (SSID), password, and encryption type. Scanning will prompt devices to join automatically.

Question 4

Is my WiFi password sent to a server?

Accepted Answer

No. The QR code is rendered entirely in your browser using JavaScript. Your credentials never leave your device.
