WiFi QR Code Generator

WiFi QR codes encode your network credentials in a standardized format that smartphones and tablets can read to automatically connect to the network. The QR code contains a specially formatted text string that devices recognize as WiFi configuration data.



The encoded string follows the format: WIFI:T:{security};S:{networkName};P:{password};H:{hidden};; where T is the security type (WPA, WPA2, WEP, or nopass), S is the SSID (network name), P is the password, and H indicates whether the network is hidden. When a smartphone camera scans this QR code, the operating system parses the string and presents a prompt to join the network automatically.



This tool generates the QR code entirely in your browser using a JavaScript QR code library. The QR encoding process converts the WiFi string into a matrix of black and white modules (the square dots) using the Reed-Solomon error correction algorithm, which allows the code to be read even if partially damaged or obscured. The tool selects the optimal QR code version (size) based on the data length and error correction level.



Your WiFi password is processed locally in your browser and never transmitted to any server. The generated QR code image can be downloaded, printed, and displayed wherever guests need to connect — reception desks, guest rooms, cafes, or offices.

1. Guest WiFi in Homes
Instead of dictating a complex WiFi password to visitors, display a printed QR code near your entrance or on the refrigerator. Guests simply scan with their phone camera and connect instantly — no more spelling out mixed-case passwords with special characters.



2. Hospitality & Hotels
Hotels, Airbnbs, and bed-and-breakfasts place WiFi QR codes on key cards, welcome sheets, and room information boards. This eliminates front desk calls about WiFi passwords and provides a seamless guest experience that earns positive reviews.



3. Restaurants & Cafes
Coffee shops and restaurants display QR codes on table tents, menus, or wall posters. Customers connect without asking staff for the password, reducing service interruptions. When the password changes, only the QR code printout needs updating.



4. Office & Conference Rooms
Meeting rooms with guest WiFi QR codes let visiting clients and contractors connect without IT support. Conference organizers include WiFi QR codes on event badges, programs, and signage for seamless attendee connectivity.



5. Retail & Customer Spaces
Retail stores, medical waiting rooms, and service centers offering customer WiFi can display QR codes alongside their branding. Easy WiFi access encourages customers to stay longer, increasing engagement and satisfaction.

• Print at a minimum size of 2x2 cm: QR codes need sufficient size for phone cameras to scan reliably. For wall-mounted codes scanned from a distance, increase to 10x10 cm or larger. The scanning distance is roughly 10x the QR code width.



• Use high contrast: Black modules on a white background provides the most reliable scanning. Avoid light-colored QR codes on colored backgrounds, which reduce scan reliability. If adding branding, keep the QR modules themselves high-contrast.



• Include the network name visually: Print the SSID (network name) as readable text alongside the QR code. This helps users verify they are connecting to the correct network, especially in locations with multiple networks.



• Update when passwords change: If you rotate your WiFi password regularly (recommended for security), remember to generate and print a new QR code each time. An outdated QR code frustrates users.



• Use WPA2 or WPA3 security: Always select WPA2 (or WPA3 if available) as the security type. WEP is obsolete and insecure. Open networks with no password should be used cautiously, as traffic is unencrypted.



• Test the QR code before printing: Always scan the generated QR code with your own phone to verify it connects to the correct network with the right password before distributing or displaying it.
