Generate free, high-resolution QR codes for websites, Wi-Fi, vCards and payments — no watermark, no expiration.
What QR codes can do
A QR code can encode any text — a URL, Wi-Fi credentials, contact information, or a payment link. Modern phones scan them from the camera app.
Which QR generator to use
Use one that (a) does not expire your code, (b) does not watermark and (c) does not require signup. Our QR Code Generator meets all three.
Best practices
Test before printing. Use high contrast. Leave at least 4 modules of quiet zone. Minimum print size: 2×2 cm close-up, 5×5 cm posters.
Wi-Fi QR codes
Format: WIFI:T:WPA;S:NetworkName;P:Password;; — scanning connects the phone automatically.
