When to Convert

Common scenarios where this conversion is useful

Converting Linux source packages

Many Linux software releases distribute as TAR.BZ2. Convert these to 7-Zip for archival or sharing with Windows and macOS users who may not have bzip2 tools.

Improving compression on backups

7-Zip's LZMA2 compression typically beats bzip2 in compression ratio. Convert TAR.BZ2 backups to 7z to save additional storage space.

Adding encryption to archives

Convert TAR.BZ2 archives to 7-Zip for access to AES-256 password protection — a feature not available in TAR.BZ2 format.

Standardizing archive formats

Teams that need a single consistent archive format across Windows, macOS, and Linux can standardize on 7-Zip by converting existing TAR.BZ2 archives.
