7Z uses LZMA/LZMA2 compression for maximum data reduction, supporting features like AES-256 encryption, solid archives, and multiple compression methods within a single archive. TAR (Tape Archive) is the foundational Unix archival format dating to 1979, designed to bundle files and directories into a single stream without any compression — preserving Unix permissions, symbolic links, and ownership metadata.
Converting 7Z to TAR extracts your compressed archive and repackages it as an uncompressed tar bundle. This produces a raw archive that any Unix system can read with the built-in `tar` command, without needing p7zip or any 7Z-specific tooling. TAR is the standard intermediate format before applying any compression method (gzip, bzip2, xz, zstd).
TAR is the lingua franca of Unix file bundling. Every Linux distribution, every macOS installation, and every BSD variant includes the `tar` command. No additional packages are needed to extract a TAR file. Build systems, Dockerfiles, package managers (dpkg, rpm), and deployment scripts routinely consume TAR archives as their base input format.
Converting from 7Z to TAR is also a prerequisite step when you need to apply a different compression algorithm. If you need .tar.bz2, .tar.xz, or .tar.zst output, starting from a TAR base lets you pipe through any compressor. This gives you flexibility that the monolithic 7Z format cannot provide.
p7zip extracts the 7Z archive contents into a temporary directory, decompressing all LZMA/LZMA2 streams and restoring the original file hierarchy. The `tar` utility then bundles the extracted files into a single TAR stream using the POSIX.1-2001 (pax) or GNU tar format. TAR applies no compression — it concatenates file headers (512-byte blocks containing name, size, permissions, timestamps, owner) with raw file data. The output file size roughly equals the sum of all contained file sizes plus header overhead (typically <1% for archives with many small files).
Completely lossless. TAR is a pure archival format that stores files in their original, uncompressed state. Every byte of every file from the 7Z archive is preserved exactly. File permissions, timestamps, symbolic links, and directory structure are all maintained. The only change is the container format — from compressed 7Z to uncompressed TAR.

7Z to TAR conversion removes compression entirely, producing a raw file bundle that any Unix tool can process. The output is ideal as a base for custom compression, Docker builds, or distribution to environments where p7zip is unavailable.
