What is BZ2 compression?

BZ2 (bzip2) is a compression format that uses the Burrows-Wheeler algorithm for higher compression ratios than GZIP, especially on text files.

BZ2 vs GZIP — which is better?

BZ2 typically achieves 10-20% better compression than GZIP but is slower. Choose BZ2 when compression ratio matters more than speed.

How much compression can I expect?

Text and data files can compress by 70-90%. Already-compressed files see minimal additional reduction.

Is this BZ2 compressor free?

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