WiFi QR Code Generator
Last updated: 2026-06-25
The WiFi QR Code Generator is a free tool that turns your WiFi network name (SSID), password, and security type into a QR code that connects automatically with a single scan.
The QR holds the standard format WIFI:T:WPA;S:name;P:password;;, and your input is never sent to a server - it is processed only on your device.
Create a WiFi QR
The WiFi password is stored in plain text inside the QR. For public places, we recommend using a guest network.
How to Use
- Enter WiFi details - Type your WiFi network name (SSID) and password exactly. They are case sensitive.
- Select security type - Choose your router's security type (WPA/WPA2, WEP, or no password). Most networks use WPA.
- Generate and share - Press Generate WiFi QR to create the QR, then save it as PNG to print or share. Guests connect automatically just by scanning.
The WiFi QR Standard Format
A WiFi QR is simply a fixed text format encoded into a QR. When a phone camera recognizes this format, it auto-fills the network name and password and offers to connect. Each field in the format is described below.
| Field | Meaning | Example |
|---|---|---|
| T | Security type | WPA / WEP / nopass |
| S | Network name (SSID) | MyCafe_WiFi |
| P | Password | password1234 |
| H | Hidden network | true (false if omitted) |
For example, with WPA security, the name MyCafe_WiFi, and the password password1234, the QR holds WIFI:T:WPA;S:MyCafe_WiFi;P:password1234;;. If you need a QR for plain text or a URL, use the QR Code Generator; for a 1D barcode, use the Barcode Generator. For more detailed usage, see the How to Use QR Codes guide.
Frequently Asked Questions (FAQ)
How does a WiFi QR code work?
A WiFi QR holds standard text in the format WIFI:T:WPA;S:name;P:password;;. When you scan it with your phone camera, the OS recognizes this format, auto-fills the network name and password, and offers to connect. It is supported by default on iOS 11+ and Android 10+.
Is the password stored in the QR? Is that safe?
Yes, the WiFi password is stored in plain text inside the QR. So when posting it in a public place, we recommend using a guest network. This tool builds the QR only in your browser and never sends your input to a server, so the operator does not collect your password.
Can I make a QR for a hidden (stealth) WiFi network?
Yes. If your SSID is hidden, turn on the hidden network option. An H:true field is added to the QR so some devices will try to connect to the hidden network correctly.
Can the password contain special characters (;, :, quotes)?
Yes. Per the WiFi QR standard, special characters such as semicolons (;), colons (:), commas (,), quotes ("), and backslashes (\) are automatically escaped (with a backslash) so they are recognized correctly.
