Make a QR code from Wi-Fi network info so guests can connect easily.

Category: Dev Tools

When to use?

Use it to make a guide card for cafes, offices, or homes so visitors connect by scanning a QR code instead of typing the Wi-Fi password.

How to use

  • Enter the Wi-Fi network name (SSID).
  • Choose the security type (WPA/WPA2, WEP, open).
  • Enter the password.
  • Download and print the QR code.

Input Explanation

Enter the router's Wi-Fi name (SSID), encryption type, and password accurately.

Calculation Basis

It assembles a standard Wi-Fi string like WIFI:T:WPA;S:name;P:password;; and encodes it as a QR code so a phone camera recognizes it as a network setup.

Usage Examples

  • Share cafe/office Wi-Fi - Make a printable QR code from the Wi-Fi SSID and password.
  • Guide guest internet access - Make a Wi-Fi QR that connects on scan.
  • Quick pre-deploy check - Check inputs and output to reduce errors before dev/ops work.

Examples

  • SSID "Cafe_Free", WPA, password "12345678" → a QR code that prompts connection on scan
  • Open network → a QR that connects by SSID alone with no password

Cautions

  • The Wi-Fi password is included in the QR code. Take care when posting it in public.
  • Specific web-standard specs or framework-only syntax may cause compatibility issues.

Guides
