  5. Click Generate QR Code, then scan it with any phone camera to test.
  6. Click Download PNG to save it for printing or sharing.

The Wi-Fi QR String Format

Wi-Fi QR codes follow a standard plain-text format that smartphone cameras parse natively:

WIFI:T:WPA;S:<ssid>;P:<password>;;
  • T — encryption type (WPA, WEP, or nopass)
  • S — SSID (network name)
  • P — password (omit when T is nopass)
  • H:true — optional flag for hidden networks
  • ;; — closing terminator

Special characters (\, ;, ,, ", :) are auto-escaped with a leading backslash so passwords containing punctuation work correctly.

Common Use Cases

  • Cafés, restaurants, Airbnbs: print the QR on a counter card so guests skip typing.
  • Office guest networks: stick the code on a meeting-room wall.
  • Home setup: save it to your phone for quick sharing with visitors.
  • IoT onboarding: bootstrap smart-home devices that scan QR codes during pairing.

FAQ

How does a WiFi QR code work?

Phones encode Wi-Fi credentials as a string formatted like WIFI:T:WPA;S:<ssid>;P:<password>;;. Modern Camera apps on iOS 14+ and Android 10+ read it natively and offer to join the network in one tap.

Is my Wi-Fi password safe?

Yes. The QR code is generated entirely in your browser using a local QR library; nothing is uploaded to any server.

Which encryption types are supported?

WPA / WPA2 / WPA3 (treated identically in the QR string), WEP for legacy networks, and 'None' for open Wi-Fi without a password.

Why doesn't the QR code work on my phone?

Older devices may need a dedicated QR-scanner app. If you plan to print the code or stick it on a wall, choose error correction level H so partial dirt or wear won't prevent scanning.

Can I print or share this QR code?

Yes. Click Download PNG, then drop the image into a flyer, business card, or printed sticker. Use Copy Wi-Fi String if you want to embed the raw payload elsewhere.
