The QR code is generated entirely in your browser — your network name and password are never sent to any server.
Understanding the WiFi QR Code Generator
WiFi QR Code Generator creates a scannable code that lets phones join your network without typing a password. You enter the network name (SSID), the password, and the security type, and the tool produces a QR code you can print for a cafe, office, guest room, or rental. Most modern iPhone and Android cameras connect automatically on scan. It generates everything in your browser, so your WiFi password is never sent to any server, keeping your network credentials private while you share access conveniently.
How it works
Your inputs are assembled into the standardized WiFi QR string format, then rendered into a QR image in your browser with a JavaScript QR library (such as qrcode.js) drawn on a Canvas. The string follows the pattern WIFI:T:<type>;S:<ssid>;P:<password>;;, where T is the security type (WPA/WPA2/WPA3, WEP, or nopass for open networks), S is the network name, and P is the password. Special characters like semicolons, commas, and backslashes in your SSID or password are escaped with a backslash so they scan correctly. A phone's camera reads the code and offers a one-tap join. Nothing is uploaded; the password stays on your device.
Worked example
Your cafe network is named 'BrewSpot' with password 'Coffee;123' on WPA2. The tool builds the string WIFI:T:WPA;S:BrewSpot;P:Coffee\;123;; escaping the semicolon in the password so it is not read as a field separator. It renders this as a QR code you print and tape by the counter. A guest opens their phone camera, points it at the code, taps the prompt, and connects, no manual typing and no password read aloud across the room.
Tips & common mistakes
- Choose WPA/WPA2/WPA3 for password-protected networks and 'nopass' for open guest networks.
- The SSID is case-sensitive and must match exactly, including spaces.
- If your password contains ; , : " or backslash, the generator escapes them automatically; do not add escapes yourself.
- For hidden networks, enable the hidden flag so devices know to search for the SSID.
- Print at a reasonable size with good contrast and test a scan before posting it publicly.

Frequently Asked Questions
How does a WiFi QR code work?
The QR code encodes your network name, password, and security type in a standard format. When someone scans it with their phone camera, the phone offers to join the network automatically — no typing required.
Is my WiFi password safe?
Yes. The QR code is generated entirely in your browser. Your network name and password are never sent to or stored on any server.
Which phones can scan it?
Most modern iPhones (iOS 11+) and Android phones (Android 10+) can read WiFi QR codes directly from the camera app. Older phones may need a QR scanner app.
What encryption should I choose?
Choose WPA/WPA2/WPA3 for almost all modern home and office networks. WEP is for very old routers, and "No password" is for open networks.
