WiFi QR Code Generator
Create a QR code that connects any phone to your WiFi network on scan — no typing the SSID or password. Perfect for cafés, Airbnbs, offices, and home guest networks. The code is generated entirely in your browser; your credentials never leave your device.
Your files never leave your device. No upload. No sign-up.
A WiFi QR code encodes your network name, password and encryption type into a single scannable string that follows the format WIFI:T:WPA;S:<ssid>;P:<password>;;. iOS 11+ and Android 10+ read this format natively from the camera app and offer a one-tap ‘Join Network’ prompt — no third-party app required. Generation runs entirely in your browser, so the SSID and password never leave your device.
How the WiFi QR code actually works
The WIFI: schema was popularised by the ZXing project and is now recognised by Apple's camera, Google's Camera, Samsung's built-in scanner and every major third-party QR reader. The exact string is WIFI:T:<WPA|WEP|nopass>;S:<ssid>;P:<password>;;, with semicolons, colons, commas and backslashes escaped by a leading backslash. Hidden networks add H:true and can also be encoded. The QR itself is fully static — nothing points back to a server, no scan is tracked, and the code keeps working forever as long as the network credentials stay the same.
Common mistakes and limitations of WiFi QR codes
If you change the WiFi password you must reprint the QR — static codes can't be updated after they're generated. Very old Android phones (pre-Android 10) and older iOS versions need a third-party QR app to auto-connect. Enterprise networks that use WPA2-Enterprise/802.1X are not supported by the WIFI: schema; only pre-shared-key networks (home and small-office WPA/WPA2/WPA3) work. If your SSID or password contain unusual characters like semicolons, the escape is handled automatically here — but hand-edited QR strings elsewhere are a common source of ‘won't connect’ complaints.
WiFi QR code FAQ
- Does this work on iPhone and Android?
- Yes. iOS 11+ and Android 10+ both recognise the WIFI: schema in the camera app and offer a one-tap ‘Join Network’ prompt with no extra app.
- Is the password stored on your servers?
- No. The QR is generated locally in your browser — the SSID and password never leave your device.
- What encryption type should I pick?
- Pick WPA for any modern home or business router; it covers WPA, WPA2 and WPA3. Use WEP only for very old hardware and ‘No password’ for fully open networks.
- Does it work with 5 GHz networks?
- Yes. The QR encodes credentials, not the radio band — as long as the SSID matches, the phone connects on whatever band the router serves.
- Can I use this for a hidden SSID?
- The base format doesn't force a hidden flag, but you can extend the QR string with H:true if you regenerate manually. Most guest use cases don't need this.
- Will it work for enterprise WiFi (WPA2-Enterprise, 802.1X)?
- No. The WIFI: schema only supports pre-shared-key networks. Enterprise SSO WiFi has to be configured through a corporate profile.
- Can I change the password without reprinting?
- No — static QR codes bake the credentials into the image. If your password changes, generate a new QR.
- Does the QR expire?
- Never. There is no server, no account, no expiry timer. As long as the SSID and password are valid, the QR works.
