BZ2 is the file format produced by bzip2, a free and open-source lossless data compression program written by Julian Seward, first released in 1996. Like gzip, bzip2 compresses a single file rather than bundling multiple files — it is most commonly used in combination with TAR (as .tar.bz2 or .tbz2) to create compressed archives. BZ2 uses the Burrows-Wheeler block-sorting algorithm combined with Huffman coding.

The Burrows-Wheeler transform rearranges characters in a block to make subsequent compression more effective, typically achieving 10-15% better compression than gzip for text files. However, bzip2 compression and decompression are both slower than gzip, and bzip2 requires more memory (especially when decompressing). BZ2 does not support streaming decompression — the compressor must process entire blocks before outputting any data.

BZ2 decompression is natively available on all Linux and macOS systems via the bunzip2 and bzip2 commands. On Windows, 7-Zip and WinRAR can decompress BZ2 files. The bz2 Python module provides native BZ2 support in Python scripts. BZ2 as a standalone format (not TAR.BZ2) is used for compressing individual files like database dumps and log archives.

BZ2 provides better compression than GZ for single-file compression but at the cost of slower processing. For archiving multiple files, use TAR.BZ2. For the best single-file compression, XZ (.xz) is now preferred. BZ2 remains a solid choice for compressing large text files where the extra compression savings justify the slower speed.
