Create a QR code that lets guests join your Wi-Fi by scanning.
Generated locally — your network details never leave your device.
How do you create a Wi-Fi QR code?
Your network details are encoded in the standard Wi-Fi QR format "WIFI:T:WPA;S:ssid;P:password;;", with special characters escaped, then rendered as a QR code in your browser. Most modern phones support these natively, so scanning the code prompts the phone to join your network automatically. For open networks, choose None and leave the password blank.
Understanding your result
Most modern phones support Wi-Fi QR codes natively. For open networks, choose “None” and leave the password blank.
Formula and method
The details are encoded in the standard Wi-Fi QR format “WIFI:T:WPA;S:ssid;P:password;;”, with special characters escaped, then rendered as a QR code in your browser.
Assumptions and limitations
The code only works for networks whose details you enter correctly, and scanning support depends on the guest's phone and camera app. It cannot fix a wrong password, an unusual security type or a hidden network, and it does not change or manage your router settings in any way.
Worked example
Scanning the code with a phone camera prompts it to join the named network using the stored password.

Frequently asked questions
Is my Wi-Fi password uploaded?
No. The QR code is generated locally in your browser and your details never leave your device.
Which security type should I choose?
Pick the type your router uses, which is usually WPA or WPA2 for home and business networks. Choose None only for a genuinely open network with no password. If you are unsure, check your router's admin page or its label, since selecting the wrong type can stop phones connecting.
Can I print the Wi-Fi QR code?
Yes. Once generated, the code is an ordinary image you can save and print at any size, from a small business card to a large poster. Keep it clear and reasonably big so cameras focus easily, and test a scan before displaying it publicly.
