Frequently Asked Questions
What is a QR code?
A QR code (Quick Response code) is a 2D barcode that smartphones can scan to instantly open a URL, connect to WiFi, add a contact, or perform other actions without typing.
What types of QR codes can I generate?
URL (website links), plain Text, WiFi credentials (SSID, password, encryption), Email addresses, and Phone numbers. Each type creates a properly formatted QR payload.
Are the QR codes stored on a server?
No — QR codes are generated entirely in your browser using the qrcode.js library. Nothing is uploaded or saved.
How do I download my QR code?
Click the Download PNG button after generating your QR code. The image is saved directly to your device at the selected size (128×128 to 512×512 pixels).
What is error correction level?
QR codes have built-in error correction. Level L (7%) works for clean digital displays. Level H (30%) allows the QR code to remain scannable even if up to 30% is obscured or damaged — useful for printed materials.
