What is a WiFi QR code?
A WiFi QR code is a special QR code that encodes your WiFi network credentials (SSID, password, encryption type). When scanned with a smartphone camera, it automatically connects the device to your WiFi network without manually entering the password.
Is this WiFi QR code generator free?
Yes, this WiFi QR code generator is 100% free with no limitations. No registration, no watermarks, no usage limits. Generate as many WiFi QR codes as you need for home, office, or business use.
How do I scan a WiFi QR code on iPhone (iOS)?
On iOS 11 and later, simply open the Camera app and point it at the WiFi QR code. A notification will appear asking if you want to join the WiFi network. Tap it to connect instantly. You can also use the Control Center WiFi QR scanner.
How do I scan a WiFi QR code on Android?
On Android 10 and later, open the Camera app or the WiFi settings and look for the QR code scan option. Point it at the QR code, and your phone will automatically connect to the WiFi network. Some Android phones have a dedicated QR scanner in the WiFi settings.
What encryption types are supported?
This tool supports three encryption types: WPA/WPA2 (most common, recommended), WEP (older, less secure), and nopass (open network with no password). WPA/WPA2 is the default and works with virtually all modern routers.
What is the WiFi QR code format?
WiFi QR codes use a standard format: WIFI:T:<encryption>;S:<SSID>;P:<password>;H:<hidden>;. T is the authentication type (WPA, WEP, or nopass), S is the network name, P is the password, and H indicates if the network is hidden.
Can I generate a QR code for a hidden WiFi network?
Yes, simply check the "Hidden Network" option when generating the QR code. This adds the H:true parameter to the WiFi string, allowing devices to discover and connect to hidden networks that don't broadcast their SSID.
Are special characters in SSID or password supported?
Yes, special characters like semicolons (;), commas (,), quotes ("), and backslashes (\) are automatically escaped using the standard backslash escape sequence. This ensures the QR code is parsed correctly by all devices.
Is my WiFi password safe when using this tool?
Absolutely. All QR code generation happens entirely in your browser using JavaScript. Your SSID, password, and other inputs never leave your device, are not sent to any server, and are not stored or logged anywhere.
Can I download the WiFi QR code as an image?
Yes, you can download the generated WiFi QR code as a PNG image (for printing) or as an SVG file (for scaling without quality loss). Both formats are ready for use in print materials, signage, or digital displays.
What size should I make the WiFi QR code?
For phone scanning at close range (30-50cm), 256px is sufficient. For wall posters or table displays, use 512px or larger. For printed materials, use SVG format or PNG at 1024px to ensure reliable scanning from a distance.
Can I use WiFi QR codes for my business?
Absolutely! WiFi QR codes are perfect for cafes, restaurants, hotels, offices, and event venues. Customers can scan to connect without asking staff for the password, improving experience while keeping your network secure.
Does this tool work offline?
Yes, once the page is loaded, WiFi QR code generation works entirely offline in your browser. No internet connection is needed after the initial page load, making it ideal for use on secure or isolated networks.
Why doesn't my phone prompt to connect after scanning?
Ensure your phone is running iOS 11+ or Android 10+. Older devices may not support WiFi QR codes natively. Also verify the encryption type matches your router settings and that the SSID and password are entered correctly.
How to Use WiFi QR Code Generator
Create a scannable WiFi QR code so guests can join your network without typing the password. The code is generated entirely in your browser — your credentials are never uploaded.
- Type your network name into the “Network Name (SSID)” field — the placeholder shows the example “MyWiFi”.
- Pick your security mode under “Encryption”: WPA/WPA2/WPA3, WEP, or No Password (Open).
- Enter the wireless key in the “Password” field to complete the connection string.
- Under “Error Correction”, “High (30%) — recommended” keeps the code readable even if partially obscured.
- Choose a “Size” such as 512 × 512, adjust the Foreground and Background colors, then use Copy to export the image.
Choose “No Password (Open)” only for guest networks; for home WiFi, WPA/WPA2/WPA3 keeps the shared QR code safe.
