WiFi QR Code Generator

Create a QR code to share your WiFi network details. Guests can scan to join instantly.

This QR code is generated entirely in your browser. No data is sent to any server. The QR code encodes your network details using the WiFi standard format.

What is the WiFi QR Code Generator?

A WiFi QR code is a square barcode that encodes your network name (SSID), password, and security type into a standard QR format (ISO/IEC 18004). When scanned, it triggers the device's native WiFi settings to auto-fill the network credentials and connect automatically.

How it works

The generator takes your network name, password, and security protocol (WPA2, WPA3, or Open), then constructs a specially formatted string starting with 'WIFI:' and encodes it as a QR image. The resulting code is a pixel grid readable by any standard QR scanner or phone camera. When scanned, Android and iOS devices interpret the WiFi parameters and attempt an immediate connection.

Examples

InputResultNotes
SSID: 'HomeNetwork', Password: 'P@ssw0rd123', Security: WPA2A 29×29 pixel QR code (Version 3) that auto-connects devices on scanTypical password length creates mid-size codes; longer passwords produce larger grids
SSID: 'GuestWiFi', Password: '12345678', Security: WPA3A 25×25 pixel QR code (Version 2) optimized for fast scanningShorter credentials = smaller, faster-scanning codes with lower error rates
SSID: 'OpenNetwork', Password: (none), Security: OpenA 21×21 pixel QR code (Version 1) with no authentication dataOpen networks require fewer bits and produce the smallest, fastest codes

How to use the WiFi QR Code Generator

  1. Enter your WiFi network name (SSID) exactly as it appears in your settings
  2. Type your WiFi password (case-sensitive if applicable)
  3. Select your security type: WPA2, WPA3, or Open (no password)
  4. Click 'Generate QR Code' to create the scannable image
  5. Download or screenshot the QR code for printing, sharing, or display
  6. Share the code with guests—they scan it with their phone camera to connect instantly

Benefits

  • Eliminates password errors and removes the need to verbally dictate complex passwords
  • Faster guest onboarding—friends and family connect in seconds without manual entry
  • Printable codes can be posted on a wall, included in rental property welcome packets, or printed on business cards
  • No app installation required; works natively with iPhone and Android camera apps
  • Securely share WiFi access without exposing credentials in plain text conversation
  • Supports all standard WiFi security protocols and works offline after generation

Tips & common mistakes

Common mistakes

  • Entering the SSID incorrectly or with extra spaces—the code will still generate but connection will fail if the name doesn't match exactly
  • Using the wrong password—even one character off prevents successful connection; double-check before generating
  • Selecting the wrong security type (e.g. WPA2 when your router uses WPA3)—this causes authentication to fail silently
  • Assuming the code works with all devices—older phones or non-standard apps may not recognize WiFi QR format (iOS 11+ and Android 10+ fully support it)

Tips

  • Create separate QR codes for guest WiFi and primary networks—easier management and lets you change one password without updating all codes
  • Laminate or frame printed codes in rental properties, cafes, or offices for durability and a professional look
  • Test the code on your own phone before sharing to catch password or SSID typos
  • Use high contrast printing (black code on white background) for reliable scanning in different lighting

Frequently asked questions

Can someone steal my WiFi password from the QR code?

Yes—the QR code contains your plaintext password. Treat it like you would any written password. Only share codes with trusted people, and don't post them publicly online. Consider creating a separate guest network with a different password for sharing.

What if I change my WiFi password after generating the code?

Any previously generated codes will no longer work—devices will fail to connect. Generate a new code immediately after password changes, and update any printed or shared copies.

Do I need an app to scan a WiFi QR code?

No. Modern iPhone (iOS 11+) and Android (10+) phones can scan WiFi QR codes using the native camera app—no separate app required. Just open the camera, point it at the code, and tap the notification that appears.

Can I generate a code for a WiFi network that's not mine?

Technically yes, but ethically no. Only generate codes for networks you own or manage. Generating codes for someone else's network without permission is a security violation.

Are WiFi QR codes the same as regular QR codes?

No—they're a specialized type. Regular QR codes can link to websites or contain plain text. WiFi QR codes use a dedicated format that devices recognize as network credentials and auto-connect.

What happens if the QR code is damaged or partially obscured?

Most QR codes include error correction (up to 30% damage tolerance). A partially torn or faded code might still scan, but a heavily damaged code will fail. Reprint if needed.
