What Is a Wi-Fi QR Code?

A Wi-Fi QR code encodes your network credentials into a scannable QR code. When a smartphone scans it, the device automatically connects to your Wi-Fi network — no need to search for the network name or type in a long password. Our free Wi-Fi QR code generator creates these codes directly in your browser. Your credentials never leave your device.

How the Wi-Fi QR Code Format Works

Wi-Fi QR codes follow a standardized format defined by the IEEE 802.11 specification: WIFI:T:WPA;S:MyNetwork;P:MyPassword;;. The format encodes the encryption type (T), SSID (S), and password (P). Modern smartphones running iOS 11+ or Android 10+ natively recognize this format through the built-in camera app — no third-party app required.

How to Generate a Wi-Fi QR Code

Enter your network SSID (the name of your Wi-Fi network), your password, and select the correct encryption type (WPA/WPA2 for most modern routers, WEP for older hardware, or None for open networks). Click Generate QR Code to create your scannable code. Use Download SVG to save it as a high-quality vector graphic for printing.

How to Do This in Code

function wifiQR(ssid, password, encryption) {
  const str = `WIFI:T:${encryption};S:${ssid};P:${password};;`;
  const qr = qrcode(0, 'M');
  qr.addData(str);
  qr.make();
  return qr;
}

import qrcode
ssid, password, enc = "MyNetwork", "Pass123", "WPA"
data = f"WIFI:T:{enc};S:{ssid};P:{password};;"
img = qrcode.make(data)
img.save("wifi_qr.png")

import "github.com/skip2/go-qrcode"

str := fmt.Sprintf("WIFI:T:%s;S:%s;P:%s;;", enc, ssid, pwd)
qr, _ := qrcode.New(str, qrcode.Medium)
qr.WriteFile(256, "wifi_qr.png")

qrencode -o wifi_qr.png "WIFI:T:WPA;S:MyNetwork;P:MyPassword;;"

Wi-Fi QR Code Generator FAQ

What is a Wi-Fi QR code?

A Wi-Fi QR code encodes your network credentials (SSID, password, and encryption type) in a standard format. Smartphones with built-in QR scanners can read it and connect to your network automatically without typing the password.

Which devices support Wi-Fi QR codes?

All modern smartphones: iPhones (iOS 11+), Android (Android 10+), and most tablets. Just point the camera at the QR code and tap the notification to connect.

Is the Wi-Fi password visible in the QR code?

The password is encoded in the QR code but not visible to the naked eye. However, anyone who can scan the QR code can read the password. Only share Wi-Fi QR codes with people you trust.

What encryption types are supported?

WPA/WPA2 (most common for modern routers), WEP (older routers), and WPA2-Enterprise or None (open networks). Select the correct type matching your router configuration.

Does this store my Wi-Fi credentials?

No. Everything runs client-side in your browser. Your SSID and password never leave your device.
