7Z archives achieve exceptional compression through LZMA and LZMA2 algorithms, often 30-70% smaller than equivalent ZIP files. TGZ is a compact filename variant of tar.gz — a gzip-compressed tar archive — using the shorter three-character extension that originated from 8.3 filename restrictions on older DOS and Windows systems. TGZ is the exact same format as tar.gz internally.
Converting 7Z to TGZ produces a gzip-compressed tarball with the .tgz extension, which is preferred in certain package management systems (notably Slackware's pkgtools), embedded system deployments, and environments where short filenames are conventional. The conversion extracts 7Z's LZMA-compressed contents and repacks them using tar + gzip.
Several specific ecosystems prefer or require the .tgz extension over .tar.gz. Slackware Linux packages use .tgz exclusively as their native package format. Helm charts for Kubernetes are distributed as .tgz files. Many embedded Linux build systems (Buildroot, OpenWrt) and cross-compilation toolchains expect .tgz source tarballs in their download directories.
The .tgz extension is also more practical for scripting and automation. A single extension (rather than the compound .tar.gz) simplifies glob patterns, file type detection, and programmatic filename handling. Some legacy systems and older POSIX tools handle single-extension filenames more reliably than double extensions.
p7zip extracts the 7Z archive into a temporary directory, decompressing all LZMA/LZMA2 streams to their original file data. The extracted tree is then bundled into a POSIX tar archive and simultaneously compressed through the gzip DEFLATE algorithm. The output is written with a .tgz extension. Internally, the file is byte-identical to what a .tar.gz file would contain — the extension is the only difference. The gzip stream includes a 10-byte header with magic number 1f8b, compression method (08 = DEFLATE), and a CRC32 + original-size footer.
Fully lossless. The files inside the 7Z archive are extracted exactly as stored and repacked into the TGZ container without any modification. Every byte, filename, permission bit, and timestamp is preserved. The TGZ format itself is just tar + gzip — a well-established, lossless archival and compression combination used for decades in production systems worldwide.
