Free WiFi QR Code Generator

What Is a WiFi QR Code?

A WiFi QR code encodes your network name (SSID), password, and security type in a machine-readable format. When scanned, the phone automatically connects to the network - no manual typing of long passwords, no miscommunication, no support requests.

How the WiFi String Works

This tool generates the standard WIFI: URI format that all modern smartphones recognize:

WIFI:T:WPA;S:MyNetwork;P:MyPassword;H:false;;

The parameters are:

• T: - Security type: WPA (covers WPA2/WPA3), WEP, or nopass (open network)
• S: - SSID (network name)
• P: - Password (omitted for open networks)
• H: - Hidden network flag (true or false)

Special character escaping: This tool automatically escapes semicolons (;), colons (:), and backslashes (\) in your SSID and password. This prevents parsing errors when your password contains these characters - a common bug in other generators.

Best Use Cases

• Airbnb & vacation rentals: Frame a WiFi QR in the living room so guests connect instantly without asking you for the password.
• Cafés & restaurants: Print on table tents or receipts - customers scan instead of asking staff.
• Offices & coworking spaces: Display at reception for visitor WiFi access.
• Home guest networks: Put a framed QR in the guest bedroom. Visitors connect without you spelling out xK9#mP$2vL.

Best Practices

• Use WPA2 or WPA3: Never use WEP - it's trivially breakable. Select "WPA" in the tool, which covers WPA2 and WPA3.
• Test with special characters: If your password contains ;, :, or \, generate the QR and scan it to confirm the connection works correctly.
• Print at 3 × 3 cm minimum: WiFi QR codes tend to encode more data than URL codes due to password length. Print slightly larger than minimum for reliable scanning.
• Update when password changes: Static WiFi QR codes have the password embedded - if you change it, you need a new code. Use a dynamic QR code if you rotate passwords regularly.
