About formats
TAR.XZ is a compound archive format combining TAR) archiving with XZ compression, developed by the Tukaani Project and led by Lasse Collin since 2009. The TAR layer bundles files preserving Unix metadata, and XZ applies LZMA2 compression within a robust container featuring CRC-32 and CRC-64 integrity checks, padding support for media storage, and a stream/block structure enabling parallel decompression. LZMA2 improves on LZMA with better handling of incompressible data and multi-threaded compression support. TAR.XZ has become the preferred distribution format for many open-source projects — the Linux kernel, GNU core utilities, and numerous other packages ship their source tarballs as .tar.xz files. One advantage is the best compression-to-decompression-speed ratio among widely supported formats — XZ achieves compression ratios comparable to 7Z while decompressing faster than bzip2, an ideal combination for software distribution. The built-in integrity verification is another strength: unlike raw LZMA streams, the XZ container includes checksums that detect corruption before data reaches the application layer. GNU tar supports TAR.XZ natively via the -J flag, and xz-utils are packaged in every major Linux distribution. The format has effectively replaced TAR.GZ and TAR.BZ2 as the default for source code distribution in the open-source ecosystem.
TGZ (also written as .tar.gz) is the most widely used compound archive format on Unix-like systems, combining TAR) archiving with gzip compression. Gzip was created by Jean-loup Gailly and Mark Adler, first released on October 31, 1992 as a free, patent-unencumbered replacement for the Unix compress utility. The TAR layer bundles files with full Unix metadata (permissions, ownership, timestamps, symlinks, hard links) into a single sequential stream, and gzip compresses it using the Deflate algorithm — a combination of LZ77 dictionary matching and Huffman coding. The resulting .tar.gz or .tgz file is the standard format for distributing source code, creating system backups, and packaging software on Linux and Unix platforms. One advantage is near-universal support — TGZ files can be created and extracted on every Unix system, Windows (via 7-Zip, WinRAR), and macOS natively, making it the safest choice when the recipient's platform is unknown. Fast decompression is another practical strength: gzip extraction is significantly faster than bzip2 or xz, important for CI/CD pipelines, container image layers, and automated deployments where extraction time matters. GNU tar supports TGZ natively with the -z flag, and the format serves as the basis for many higher-level packaging systems. While XZ offers better compression ratios, TGZ remains the default choice when broad compatibility and extraction speed are priorities.
