The world's best genomic compressor

The best FASTQ, BAM, VCF compression.


Genozip provides the best compression of any commercial or open source compression software, for almost every case we tested.

Proven in large deployments

Genozip is being used in production environments with 100s of TB of FASTQ and BAM data.


Verifiable with MD5 or Adler32


Easily scales to 50 - 100 cores


Optionally, the data can be encrypted while being compressed, without affecting compression speed. Genozip uses AES-256 which is the US government standard and an ISO standard encryption algorithm.

Feature rich

--tar option to archive entire directories 

- Supports 17 common genomic file formats + generic

- optional base quality score binning to improve compression.

- analysis tools

- much, much more

Integration with pipelines

- Genozip is an easy to use command-line tool:

- genozip and genounzip for compressing and decompressing files

- genocat for viewing or subseting a compressed file

Genozip™ Academic

Price: free

To qualify for a free academic license, two conditions must be met: 1. Your institution must be a recongized academic research institution and 2. The data being compressed was not obtained from or for commercial activities.

Note: data obtained from a service such as a clinical, diagnostic, sequencing or data analysis service, is considered commercial and hence does not qualify for the academic license. This is because someone (the patient, insurer, client...) paid your institution for the service. This is even if the institution itself is a non-profit.

Genozip Academic is feature-wise identical to Genozip Enterprise, but access to support is not guaranteed to be available. See: Installation instructions and Frequently Ask Questions.
