How it works

The payload is segmented into QR data modes, encoded into codewords, padded to a selected version, and protected with Reed–Solomon error correction before finder patterns, masking, and modules are rendered. Version and error-correction level determine capacity and symbol size.

  • Higher versions carry more data; stronger correction consumes more space.

Worked example

URL QR Code
Generate a QR code for a website URL
Input
											Text: https://example.com
Size: 200
Error correction: M
Dark color: #000000
Light color: #ffffff
Output

When to use this

Web links, event tickets, and device labels generate QR symbols.

Edge cases

  • Long payloads can exceed the selected version capacity.
  • A cropped quiet zone prevents reliable detection.
  • A logo covering modules consumes error-correction margin.
