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.
- Decoding. HCC2D Decoder is available on Google Play, on Huawei AppGallery, and on the App Store for iPhone.
- Encoding. Beyond the online generator, HCC2D Encoder is also available on the App Store for Mac. An open-source single-file command-line C encoder is also available on GitHub, and Debian/Ubuntu users can install the packaged CLI encoder from the official HCC2D APT Repository. HCC2D API is available for programmatic generation from any language or platform.
- Air-Gapped File Transfer. HCC2D Streamer is available on the App Store for Mac and on the Microsoft Store for Windows. The app transfers files from a Mac or PC to a smartphone (iOS or Android) via air-gapped optical streaming of HCC2D codes -- no network or cables required.
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.
