A Java library providing LZ4 compression and decompression with fast, high-compression, and interoperable frame modes. It offers JNI bindings to the C implementation plus pure-Java and Unsafe-based ports, all producing interchangeable streams.

Use cases

  • compress data in a Java application with LZ4
  • read LZ4 frame streams produced by other languages or the lz4 CLI
  • speed up serialization of large in-memory datasets
  • choose between JNI speed and pure-Java portability for compression
  • decompress LZ4 streams with low memory overhead

When to choose

  • you need very fast compression/decompression on the JVM
  • you need interoperable LZ4 frame streams across languages
  • you want a choice of JNI, Unsafe, or pure-Java implementations

When to avoid

  • starting a new project - the official project is discontinued; use the community fork (yawkat/lz4-java)
  • you need maximum compression ratio rather than speed
  • you need a non-JVM language
