HCC2D Encoder — Written by Marco Querini

HCC2D Codes

HCC2D (High Capacity Colored Two-Dimensional) is a colour barcode format that extends QR codes by encoding data in coloured cells, increasing data density while preserving QR-style robustness and error correction.

HCC2D Decoder is available on Google Play, on Huawei AppGallery, and on the App Store for iPhone. If you want to integrate HCC2D codes into your own system, use the HCC2D API to generate them programmatically from any language or platform.

How it works

Choose a template, set error correction, and either type content or upload a file. The server runs the standalone encoder and returns a PNG you can save or embed.

  • BYTE-mode encoding
  • Selectable EC level
  • Optional fixed version
  • PNG output for download or preview

Generate a Code

Templates help you encode common QR content without manual formatting.

By generating a code, you acknowledge that your input will be processed on our servers as described in the Privacy Policy and Terms of Service.

Ready.

Payload too large

        
The data exceeds the maximum supported payload size.

        
    
          
  • Lowering the error correction level, for example L instead of H
  • Leaving version on Auto so the encoder can choose the largest supported version
  • Reducing the amount of data
    •
