Are the generated QR codes free to use commercially?

Yes. QR codes themselves are in the public domain. QR codes generated with our tool can be used freely for personal and commercial purposes without any attribution or license fee.

What is error correction level in QR codes?

Error correction allows a QR code to be readable even if part of it is damaged or covered. Levels: L (7% damage), M (15%), Q (25%), H (30%). Higher levels make the QR code larger but more resilient — recommended for printed materials.

What is the maximum data a QR code can hold?

Up to 7,089 numeric characters, 4,296 alphanumeric characters, 2,953 bytes of binary data, or 1,817 Kanji characters at the lowest error correction level. Simpler data (short URLs) creates smaller, faster-scanning QR codes.

Can I generate QR codes for WiFi networks?

Yes! Enter your WiFi SSID, password, and security type (WPA/WEP/None). Scanning the QR code connects to the network automatically on Android and iOS without manually typing the password.

What format should I download the QR code in?

For print: download SVG — it scales to any size without pixelation. For digital use: PNG at 512px or higher. Avoid JPG as compression artifacts can make the QR code harder to scan.
