WiFi QR Code Generator
Generate a scannable QR code for your WiFi network. Share your WiFi password with guests instantly — they just scan the code with their phone camera and connect automatically. Supports WPA/WPA2, WEP, and open networks.
How Does the WiFi QR Code Generator Work?
The WiFi QR Code Generator creates a scannable QR code that contains your WiFi network credentials in a standardized format recognized by smartphones and tablets. When you enter your network name (SSID), password, and encryption type, the tool constructs a WiFi connection string following the WIFI:T:{type};S:{ssid};P:{password};; format. This format is an industry standard supported by both Android and iOS devices, allowing automatic WiFi connection when the QR code is scanned.
The QR code itself is generated as a two-dimensional barcode that encodes the WiFi connection string into a matrix of black and white modules. Each module represents a binary value, and the pattern encodes your network information along with error correction data that allows the code to be read even if partially damaged or obscured. The tool uses a reliable QR code generation service to create high-quality, scannable codes at 300x300 pixel resolution, suitable for both screen display and printing.
This tool supports three encryption types that cover virtually all consumer WiFi networks. WPA/WPA2 is the most common modern encryption standard and is the default selection. WEP is an older, less secure encryption method still found on some legacy networks. The "No Password" option generates a QR code for open networks that do not require authentication, which is useful for public hotspots or guest networks that use captive portals instead of WPA passwords.
How to Use the WiFi QR Code
Once you generate the QR code, anyone with a modern smartphone can connect to your WiFi network by opening their camera app (or a QR code scanner) and pointing it at the code. On Android devices running version 10 or later, the built-in camera app recognizes WiFi QR codes and offers to join the network with a single tap. iPhones running iOS 11 or later similarly detect WiFi QR codes through the camera app. The entire connection process takes just a few seconds, eliminating the need to verbally share complicated passwords or type them manually.
You can download the generated QR code image and print it on a card, sticker, or sign. Many businesses print WiFi QR codes on table tents, wall posters, or receipts. Vacation rental hosts include them in welcome packets. Home users often place a printed QR code on their router or refrigerator. The downloaded image is a standard PNG file that can be inserted into documents, presentations, or printed at any size while remaining scannable.
Security Considerations
Your WiFi credentials are encoded directly in the QR code, so anyone who can see or photograph the code can extract your network password. Place printed QR codes in areas where only authorized people have access. If you change your WiFi password, regenerate and replace the QR code. For businesses, consider using a separate guest network with its own QR code rather than sharing your primary network credentials. This isolates guest traffic from your business systems and allows you to change the guest password without affecting your internal operations.
Privacy Note About This Tool
This tool sends your WiFi credentials to an external QR code generation API to create the image. While the API provider does not store the data permanently, the credentials are transmitted over HTTPS during generation. If you require fully offline, private QR code generation where your credentials never leave your device, consider using the DeviceGPT mobile app which generates WiFi QR codes entirely on-device without any network requests.
