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.

Benefits of Using a Wi-Fi QR Code

For Home Users

Print and stick on the fridge for guests
Share without revealing the password verbally
Works with all modern smartphones
No app needed — native camera support

For Businesses

Display at reception or waiting areas
Include in digital signage or menus
Reduce IT support requests for passwords
Easily update by regenerating the QR code

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.

Sharing Wi-Fi network credentials using a QR code is the modern, seamless standard for homes, offices, cafes, and conference venues. Typing long, complex 20+ character WPA2 or WPA3 passwords on mobile virtual keyboards is notoriously frustrating and error-prone. The Wi-Fi QR code standard, pioneered by the ZXing project and supported natively by all modern iOS (iOS 11+) and Android (Android 9+) camera apps, encodes network configuration in a standardized URI format: `WIFI:S:MyNetwork;T:WPA;P:MyPassword;H:false;;`. When a smartphone camera scans this QR code, the operating system decodes the SSID, authentication protocol (WPA/WPA2/WPA3, WEP, or Open), and network key, displaying a native prompt: 'Join MyNetwork Wi-Fi Network?'. Tapping the prompt connects the device automatically without revealing the password or requiring manual entry. Crucially, Wi-Fi passwords often contain special characters like semicolons, colons, backslashes, and quotation marks, which must be escaped properly per IEEE 802.11 standards to prevent connection failures. WebUtil's Wi-Fi QR Code Generator produces high-resolution, vector-accurate QR codes with proper escaping, hidden SSID support, and print-ready downloads—running 100% client-side so your network passwords remain strictly private.

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

How does scanning a Wi-Fi QR code connect a phone without typing a password?

The QR code encodes your network SSID, encryption type, and password in standard ZXing format. When scanned, iOS and Android cameras automatically interpret this configuration and prompt you to join the network.

Does this QR code work on both iPhones (iOS) and Android devices?

Yes. All modern iPhones running iOS 11 or later and Android devices running Android 9 or later natively scan and connect to Wi-Fi QR codes using their default camera apps.

What Wi-Fi security protocols are supported (WPA2, WPA3, WEP)?

WebUtil supports WPA/WPA2/WPA3 (the modern standard for virtually all routers), legacy WEP, and Open (unencrypted) networks.

Can I create a QR code for a hidden Wi-Fi network (hidden SSID)?

Yes. Check the 'Hidden Network' option. This sets the H:true parameter in the QR code so devices scan for non-broadcasting SSIDs.

Is my home or office Wi-Fi password stored on your servers?

No. The QR code is generated entirely in your browser using client-side JavaScript. Your Wi-Fi network name and password never touch any server.

What is the best way to print or display a Wi-Fi QR code for guests?

Download the generated QR code, print it on paper or cardstock, and frame it near your router, living room, office lobby, or cafe counter for easy guest scanning.
