Data compression often requires a compromise between speed and size. High-ratio compression tools can significantly reduce file sizes, but they often require substantial processing time. Conversely, fast tools may not reduce file sizes as effectively.
: Resolves a specific data corruption issue (Issue #560) that occurred only in v1.8.2 at compression level 9 with data blocks larger than 64 KB. This makes v1.8.3 a highly recommended security update for Windows users. : Introduces the

LZ4 is primarily a command-line tool. Open Command Prompt ( cmd ) or PowerShell to use it.
To understand where LZ4 excels, look at how it stacks up against other popular compression algorithms: Focus Area Relative Compression Speed Relative Decompression Speed Space Saved Ratio Ultra-Fast (~750 MB/s) Extreme (~4.5 GB/s) Low to Moderate ZSTD (Zstandard) Fast (~500 MB/s) Very Fast (~1.5 GB/s) GZIP / DEFLATE Legacy Standard Slow (~30 MB/s) Moderate (~400 MB/s) LZMA (7-Zip) Max Size Reduction Ultra-Slow (~5 MB/s) Slow (~100 MB/s)
