LZ4
LZ4 CompressedExtremely fast compression algorithm focused on speed over ratio. Designed for scenarios where decompression speed matters more than file size.
Best for
Real-time systemsGame assetsIn-memory compressionDatabase pages
Advantages
- + Fastest decompression
- + Very fast compression
- + Low CPU usage
- + Predictable performance
Limitations
- − Lower compression ratio
- − Larger output
- − Less common for archives
- − Single file only
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
