WiFi QR Code Generator

A WiFi QR Code Generator turns your network name and password into a QR code that a phone camera reads to connect automatically. Instead of reading a password off a sticky note and typing it character by character, a guest points their camera at the code, taps the "Join network" prompt, and they are online. The connection details are encoded directly into the black-and-white pattern using the standard WIFI: format that iOS and Android have understood natively for years.

The code is built from a short join-string that looks like WIFI:T:WPA;S:MyNetwork;P:MyPassword;;. The T field is the authentication type, S is the SSID, and P is the pre-shared key; the generator escapes any semicolons, commas, or backslashes in your credentials so a password like p@ss;word survives intact. That string is then encoded as a QR matrix with Reed-Solomon error correction following ISO/IEC 18004, the same specification every scanner app implements, so the result works on any modern phone without a special reader.

Everything runs inside your browser. Your SSID and WiFi password are never uploaded, logged, or attached to a scan-tracking dashboard - the encoding happens in JavaScript on your device, and the tool keeps working with the network cable unplugged once the page has loaded. The QR code it produces is static, meaning the credentials live in the image itself with no short link in the middle that could expire or be switched off. Print it, laminate it, and stick it on the fridge or the cafe counter; it will keep working for as long as the password does.

The built-in sample makes a good worked example for this QR code generator for WiFi. With Toolz Cafe Guest as the network name, flat-white-2026 as the password and WPA/WPA2/WPA3 selected, the encoded string is WIFI:T:WPA;S:Toolz Cafe Guest;P:flat-white-2026;; and the preview shows Version 4 with 33×33 modules at error correction M. Switch to H and the same QR code WiFi generator output grows to Version 6, 41×41. A hidden network with the password p@ss;word:1 encodes as P:p@ss\;word\:1;H:true, so the delimiters survive the scan.
