How it works
The QR encodes a standard WIFI:T:WPA;S:<ssid>;P:<password>;; string. Most modern phone cameras read it and offer to join the network with one tap.
Special characters in the SSID or password (\ ; , : ") are escaped with a backslash so the code scans correctly.
How the WiFi QR Code Generator Works
This tool turns your network details into a scannable WiFi QR code. Enter the network name (SSID), the password, and the security type (WPA/WPA2/WPA3, WEP, or open). When a guest scans the code with their phone camera, the device reads it and offers to join your WiFi instantly, with no typing.
What the Code Encodes
The QR stores a standard payload defined by the WiFi Alliance:
WIFI:T:WPA;S:<your SSID>;P:<your password>;;
The T field is the security type, S is the network name, P is the password, and an optional H:true marks a hidden network. Reserved characters (\ ; , : ") in your SSID or password are automatically escaped with a backslash so the code scans reliably.
Worked Example
For a WPA2 network named HomeNetwork with the password s3cret-pass, the tool builds:
WIFI:T:WPA;S:HomeNetwork;P:s3cret-pass;;
It then encodes that string as a QR code. A guest points their camera at it, taps the prompt, and connects without ever seeing or typing the password.

| Events | One poster connects the whole room |
Tips for Safe Sharing
- Use a guest network so your QR code never exposes your main password.
- Display it where you trust people — anyone who scans the code can connect.
- Higher error correction (Q or H) survives smudges and small logos if you place the code on a printed card.
Download the QR as an SVG to print it crisply at any size, or display it on a screen for guests to scan.
Frequently asked questions
How does a WiFi QR code work?+
A WiFi QR code stores your network name, password and security type in a standard WIFI: text string. When someone points their phone camera at it, the phone reads the code and offers to join the network automatically, so they never have to type the password.
Is it safe to share my WiFi as a QR code?+
It is convenient for guests, but the QR code contains your password in readable form, so anyone who scans or photographs it can connect. Display it only where you trust visitors, and consider creating a separate guest network so your main password stays private.
Do all phones support WiFi QR codes?+
Most modern phones do. iPhones running iOS 11 and later and Android 10 and later read WIFI QR codes directly from the camera app. Older devices may need a dedicated QR scanner app, after which they can still join the network.
Why does my SSID or password have backslashes in the encoded string?+
The WIFI format reserves the characters backslash, semicolon, comma, colon and double quote. If your network name or password contains one of these, this tool escapes it with a backslash so the code scans and connects correctly. The original credentials are unchanged.
What is a hidden network in the WiFi QR code?+
A hidden network does not broadcast its name, so devices cannot see it in the WiFi list. Ticking the hidden option adds H:true to the QR code, telling the scanning device to connect even though the network name is not advertised.
