Frequently Asked Questions
What is a QR code?
A QR code (Quick Response code) is a two-dimensional barcode that can be read by smartphones and QR scanners. It stores data like URLs, text, contact information, Wi-Fi credentials, and more.
Are these QR codes free to use?
Yes. All QR codes generated here are completely free to use, with no watermarks, no expiration, and no tracking. You can download and use them anywhere.
What data types do you support?

Can I customize the QR code design?
Yes. You can change module style (square, rounded, dots, circle, diamond, pixel, hexagon, minimal), eye style, colors, gradient, background, and add a logo.
What is error correction?
Error correction allows QR codes to be read even when partially damaged or obscured. Levels range from L (~7% recovery) to H (~30% recovery). Higher levels mean denser codes but better reliability.
Can I add a logo to my QR code?
Yes. You can upload a logo image. The safe size is automatically calculated based on your error correction level to ensure the QR code remains scannable.
