Frequently Asked Questions

How do I share WiFi with a QR code?

Enter your network name (SSID) and password into this tool, select your encryption type, and click Generate. The QR code encodes your WiFi credentials in a standard format. Anyone can scan it with their phone camera to connect instantly.

Can I create a QR code for a WPA2 or WPA3 WiFi network?

Yes. This tool supports WPA/WPA2, WPA3, WEP, and open (no encryption) networks. Select the matching encryption type from the dropdown to generate a compatible QR code.

Does the WiFi QR code work on both iPhone and Android?

Yes. Both iOS (11+) and Android phones can scan WiFi QR codes using their built-in camera app. No additional app is needed. Simply point the camera at the QR code and tap the notification to connect.

Is my WiFi password safe when generating a QR code?

Yes. The QR code is generated entirely in your browser. Your WiFi password is never sent to any server. The password is encoded directly into the QR image on your device.

Can I create a QR code for a hidden WiFi network?

Yes. Toggle the 'Hidden Network' option before generating. The QR code will include a flag telling the scanning device that the network SSID is hidden, so it connects properly.

What format does the WiFi QR code use?

WiFi QR codes use the standard WIFI: URI scheme: WIFI:T:<encryption>;S:<SSID>;P:<password>;H:<hidden>;;. This format is recognized by all modern smartphone operating systems.

Can I download or print the WiFi QR code?

Yes. After generating, click the 'Download PNG' button to save the QR code as an image file. You can then print it, add it to a sign, or share it digitally.

Does the QR code stop working if I change my WiFi password?

Yes. The QR code contains the password at the time of generation. If you change your WiFi password, you need to generate a new QR code with the updated credentials.
