What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-29, confidence not recorded

A fork of 7-Zip adding modern compression codecs (Zstandard, Brotli, LZ4, LZ5, Lizard, Fast LZMA2) to the archiver's GUI and CLI. It can be installed as a full application or as codec plugins for an existing 7-Zip installation.

Use cases

  • compress archives with zstandard instead of deflate
  • create 7z archives using lz4 or brotli codecs
  • fast multithreaded file archiving
  • add zstd codec to existing 7-Zip install
  • compress backups quickly to USB drives

When to choose

  • you want 7-Zip with faster modern codecs like zstd or lz4
  • you need a GUI archiver with zstandard support on Windows

When to avoid

  • you only need standard 7z/zip compatibility
  • you need a library to embed compression in your own code
