Build a QR code for a Wi-Fi network. The form opens on MyHomeWiFi and the visible password StrongPassword123!. The text inside the code is WIFI:T:WPA;S:MyHomeWiFi;P:StrongPassword123!;H:false;;. The preview loads that image from QuickChart, so the network name and password are part of the image request.
More helpers are in Utility tools.

WiFi QR preview
WiFi payload
WIFI:T:WPA;S:MyHomeWiFi;P:StrongPassword123!;H:false;;
Print this QR near your router, guest room, or office desk so users can join WiFi without typing long passwords.
It writes a WIFI: string and asks QuickChart to draw it as a QR image. The fields are encryption (T), network name (S), password (P), and hidden (H). Every payload ends with ;;.
The ZXing wiki section “Wi-Fi Network config (Android, iOS 11+)” uses this shape and says a reader can prompt before configuring Wi-Fi. This page does not connect a phone. It also always writes H, including H:false, and it keeps the password text when you choose Open network.
Copy WiFi payload copies the string. Download QR opens the QuickChart image and requests the file name wifi-qr-code.png or wifi-qr-code.svg. The tool is not affiliated with QuickChart.
Four steps. The payload and the image update as you type.
The name, the visible password StrongPassword123!, WPA, and H:false are already filled in.
The line under the preview is the text inside the QR, ending with two semicolons.
WEP, Open network, and Hidden SSID network rewrite T or H. Open network keeps the password text.
Copy WiFi payload copies the WIFI: line. Download QR requests the PNG or SVG from QuickChart.

Short definitions for the words on this page.
The text encoded in the QR. This form writes T, S, P, and H, then two semicolons.
The network name. The sample is MyHomeWiFi. A blank box becomes the name WiFi.
The value written when Open network is selected. The password box is still copied into P.
The hidden-network flag. This form writes H:false or H:true on every payload.
The preview and download load an image from quickchart.io and include the WIFI: string in that address.
The MyHomeWiFi sample, why Open network still keeps the password, and why the preview sends the string to QuickChart.
