A Wi-Fi QR code stores a network name (SSID) and, when applicable, its password as text inside an image. Wi-Fi QR Code builds a WIFI: payload and shows a scannable Preview in your browser. A device’s camera may offer to join the network; this page does not join it for you.
Make a dummy network code
Set Network name (SSID) to DemoNet, Password to demo-pass, and Security to WPA / WPA2 / WPA3. Payload should read WIFI:T:WPA;S:DemoNet;P:demo-pass;;. The preview displays a QR code for that text. Download PNG and Download SVG save the code as images. If the name is empty, the preview clears and asks for a network name. Hidden network adds an H:true field for networks that do not broadcast their name.
The QR image contains the password. Anyone with a copy can decode the text even if they cannot currently reach the network. Use an isolated guest network for sharing, keep printed codes in controlled places, and rotate credentials when access should end. The tool cannot test your router’s settings or promise every scanner supports the selected security mode.

Questions you might have
- Does it work on an iPhone?
- Many mobile cameras recognize this Wi-Fi QR format, but support and prompts vary by device and OS version. Test the downloaded code on the devices that guests will use.
- Is it safe to print the password in a QR code?
- Treat a printed code exactly like the password itself — anyone who can photograph it can join the network. If you hand one out and later change your mind, change the password.
- Which security type should I pick?
- Choose the mode your router actually uses. The tool writes
T:WPAfor the WPA / WPA2 / WPA3 option,T:WEPfor WEP, andT:nopassfor an open network; it does not negotiate with your router or check device compatibility.
