What is a .TGZ file?
TGZ is a TAR archive compressed with gzip, the classic way to bundle files on Unix.
- Did you know
- TGZ simply pairs the 1979 TAR format with 1992’s gzip compression.
- The gzip half was written by Jean-loup Gailly and Mark Adler as a patent-free replacement for the older Unix compress tool.
- Gzip uses the DEFLATE algorithm, a blend of LZ77 matching and Huffman coding.
- What Analyser shows you
- Browse the file tree and compression details of archives without extracting them: ZIP in pure JavaScript, and RAR, 7z, TAR and compressed tarballs (.tar.gz / .tgz, .tar.xz, .tar.zst, .tar.bz2) through a bundled libarchive engine - click any file inside to analyse it. A single compressed stream (.gz, .xz, .zst, .lz4, .lzma, .Z) is decompressed so the file within can be opened; bare .bz2 streams are identified only.
- Open a .TGZ file
- Drag a .TGZ file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
