* expandable: clean design with heavy use of interfaces as contracts makes integrating and expanding the code easy. No dependencies.
* efficient: the code is optimized for efficiency (trade-off between compression ratio and speed).

Kanzi supports a wide range of compression ratios and can compress many files more than most common compressors (at the cost of decompression speed).
It is not compatible with standard compression formats.
Kanzi is a lossless data compressor, not an archiver. It uses checksums (optional but recommended) to validate data integrity but does not have a mechanism for data recovery. It also lacks data deduplication across files.

Unlike the most common lossless data compressors, Kanzi uses a variety of different compression algorithms and supports a wider range of compression ratios as a result. Kanzi is also multithreadead by design and generates a seekable bit stream. It is not compatible with standard compression formats. Kanzi is a lossless data compressor, not an archiver. It uses checksums (optional but recommended) to validate data integrity but does not have a mechanism for data recovery. It also lacks data deduplication across files.
