LZMA
Lempel–Ziv–Markov chain AlgorithmHigh-ratio compression used by 7-Zip and the .lzma format. Predecessor to LZMA2/XZ — offers excellent compression but slower speeds.
Best for
Maximum compressionEmbedded systems firmwareSingle-file compression7-Zip archives
Advantages
- + Excellent ratio
- + Low decompression memory
- + Open source
- + Used in 7z format
Limitations
- − Slow compression
- − No multi-threading
- − Superseded by XZ/LZMA2
- − High compression memory
Target
7Z
7-Zip ArchiveHigh-compression archive format by Igor Pavlov using the LZMA/LZMA2 algorithm. Typically achieves 30–70% better compression ratios than ZIP. Open-source and free under LGPL.
Best for
Maximum compressionLarge file archivingSoftware distributionSpace-constrained backups
Advantages
- + Best-in-class compression
- + Strong AES-256 encryption
- + Open format (LGPL)
- + Solid archive mode
Limitations
- − Slower than ZIP
- − Not natively supported on all OS
- − Slower random access
- − High memory usage at max compression
