Online QR Code Generator for direct calling This is a * free QR code demo service to generate QR codes online for direct calling. The QR codes can be generated in colour with transparency selectable for fore and background.
This service will give you full control over: The block size The padding size The border size The background color The block color The border color The image below explains each of these values: If the block size is large the generated QR code is more stable and easier to read with a QR code scanner. On the other hand, as the QR code symbol size gets larger, a larger printing area is required. It is recommended to set the block size to 5 px. The generated QR code image can be very large depending on the number of characters entered, block size, padding size and border size.
