TAR.BZ2 at a glance
TAR.BZ2
Convert to tar.bz2 when you need a Unix-friendly source or file-tree distribution with better compression than gzip and good compatibility with older tooling.
It is suitable for project source releases, research datasets, and archival bundles aimed at technical recipients.
For new high-compression releases, tar.xz or tar.zst may be more attractive, but tar.bz2 remains a reasonable compatibility target.
TAR at a glance
TAR
Convert to TAR when preserving a filesystem tree matters more than built-in compression.
It is the right target for Unix backups, source code snapshots, deployment bundles, container filesystem exports, and any workflow that needs to retain permissions, symlinks, and directory layout cleanly.
Use plain TAR when another layer will handle compression or transport, and use a tar-compressed variant when you want the same packaging semantics with reduced size.
TAR is the practical archive target for infrastructure and server-oriented workflows rather than casual end-user downloads.

What changes when converting TAR.BZ2 to TAR?
This conversion changes how the format behaves in downstream tools and delivery environments.
What should I review after converting TAR.BZ2 to TAR?
Check the exported file for tar itself is a container, not a compression format.; Windows-first casual users may find tar-based archives less familiar than ZIP..
