What is XZ compression?

XZ is a compression format using the LZMA2 algorithm. It typically achieves the best compression ratios among common formats, making it ideal for distributing large files.

XZ vs GZIP vs BZ2 — which should I use?

XZ achieves the best compression but is the slowest. GZIP is the fastest but compresses less. BZ2 is in between. Choose XZ for maximum compression, GZIP for speed.

How much compression can I expect?

Text files can compress by 70-95% with XZ, typically 5-15% better than BZ2 and 15-30% better than GZIP.

Is this XZ compressor free?

Yes, completely free with no limits. Compress as many files as you need.
