Generate WiFi QR codes instantly. Scan to auto-connect — no password typing. Supports WPA/WPA2/WPA3, WEP, open networks, and hidden SSIDs.

How does a WiFi QR code work?

Your phone camera reads the QR code's WIFI: payload and prompts to join the network. iOS 11+, Android 10+, and most camera apps support this natively without a separate scanner.

Is my password sent anywhere?

No. The QR code is built entirely in your browser using a small JavaScript library. Nothing leaves your device — no server upload, no logging, no tracking.

Which security types are supported?

WPA / WPA2 / WPA3 (share the same type token), WEP, and open networks (no password). WPA3-only routers without WPA2 fallback may still need manual setup on older devices.

Why does my generated QR code not connect?

Common causes: SSID typo (case-sensitive), wrong security type, special characters in SSID/password that need escaping, or 5GHz-only network that the scanning phone doesn't support.

Can I use this for a hidden network?

Yes — check the 'Hidden network' box. Note that some Android versions still won't auto-connect to hidden networks from QR; the user may need to manually add it.

What's the largest password I can encode?

WiFi passwords are limited to 63 characters by the WPA standard. The QR code itself can hold more, but anything beyond that won't work on the network.

How should I print the QR for guests?

Pick the 512×512 or larger size, print on white paper, and keep at least 1 cm of white margin around the code. Avoid glossy paper that reflects flash during scanning.
