This is a free online QR code generator. Select an option to change the style, drag the slider to adjust the size of the QR code.If you want to include text/image/icon in the QR code, please select a higher fault tolerance. For example, 7% of fault tolerance means you can put an icon in the QR code, but the icon cannot occupy more than 7% of the area. Therefore, we suggest you select a 35% fault tolerance if you wish to put an image in the code. The higher the fault tolerance, the more dots there are in the QR code. A large number of dots slow down the scanning of the QR code so there is a trade-off.Once you have created a QR code, do test it using multiple devices.
