What is a QR code generator?

A QR code generator encodes a URL, text, Wi-Fi login, or contact card into a scannable image. Customize size and colors, then download or print.

This WiFi QR code generator builds scannable codes for WPA, WEP, and open networks using the standard `WIFI:` format. Enter SSID, password, and encryption type—guests scan with a phone camera to connect without typing credentials. Codes are generated on your device.

WiFi QR codes embed network credentials in the image using the WIFI: format supported by modern iPhone and Android cameras. Prefer a guest SSID when posting codes in lobbies or rentals.

Match encryption to the router: most home and office networks use WPA2/WPA3 (select WPA here). Open networks omit the password field. Wrong encryption types often fail silently on scan.

SSID and password special characters (semicolon, backslash, quotes) are escaped automatically. Still type the SSID exactly as the device broadcasts it—including capitalization and spaces.

Anyone who scans receives the password. Rotate guest credentials periodically if QR posters are public, and avoid publishing your primary home network code on social media.

How to use this tool

Enter the network name (SSID), choose WPA/WPA2/WPA3, WEP, or Open, enter the password when required, optionally mark the network as hidden, then generate and download the PNG. Print or display the code where trusted guests can scan.

Worked example

Example A — WPA `GuestNetwork` / `Summer2024` encodes `WIFI:T:WPA;S:GuestNetwork;P:Summer2024;;`. Example B — open `CafeFree` encodes `WIFI:T:nopass;S:CafeFree;;`. Example C — special characters in the SSID are escaped so phones still parse the payload.

When to use this

  • Office reception and conference room signage.
  • Airbnb or rental property welcome packets.
  • Event venues with temporary guest WiFi.
  • Printing a guest QR without sharing the primary network.

Common mistakes

  • Posting primary home network QR codes on public social media.
  • Using the wrong encryption type—phones fail to connect silently.
  • Special characters in SSID or password breaking the WIFI: format (this tool escapes them).
  • Typing an SSID that does not match the router’s broadcast name.

How it works

Builds a standard WIFI: payload from SSID, encryption type (WPA/WEP/open), optional password, and hidden-network flag, then encodes it as a PNG QR code in the browser with qrcode. Guests scan with a phone camera or WiFi settings to join without typing the password.

Limitations

Generated codes are static images. Test scanning at the intended print size before production use.

FAQ

Frequently asked questions

Do iPhone and Android both support WiFi QR?

Modern phones scan WiFi QR codes from the camera app or WiFi settings and prompt to join.

Can I hide the password on the printed card?

The QR encodes the password—anyone who scans gets access. Use a guest network with limited access when posting publicly.

WPA3 support?

Choose WPA for WPA/WPA2/WPA3 networks. Match the type your router uses; mismatches prevent connection.

How is this different from the generic QR code generator?

This page builds the WIFI: payload from SSID, encryption, and password fields. The generic QR tool encodes freeform text or URLs only.
