Project Overview

BZip3 is a better, faster, and stronger spiritual successor to BZip2. It features higher compression ratios and better performance thanks to an order-0 context mixing entropy coder, a fast Burrows-Wheeler transform code using suffix arrays, and a RLE with Lempel Ziv+Prediction pass. BZip3 excels at compressing text or code.

Key Features

  • Order-0 context mixing entropy coder
  • Fast Burrows-Wheeler transform using suffix arrays
  • RLE with Lempel Ziv+Prediction pass
  • Parallel compression support
  • High compression ratios

Target Audience

  • Users who need high-compression text/code compression
  • Developers and system administrators

Quick Start

  1. Install: brew install bzip3 (macOS)
  2. Or build from source: ./bootstrap.sh && ./configure && make && sudo make install
  3. Use the bzip3 command to compress/decompress files

Core Advantages

  • Higher compression ratio than BZip2
  • Parallel compression support
  • Excels at compressing text and code
  • Open-source and free

System Requirements

  • OS: Cross-platform (Linux, macOS, Windows)
  • Architectures: x86_64, arm64
