GZ → TAR

Learn about the formats: What is TAR? What is GZ?

Easily convert GZ compressed archives into TAR files without losing data. This tool is ideal for users who need to remove Gzip compression while maintaining the original archive structure.

The GZ format is a single-file compression format based on the DEFLATE algorithm, while TAR (Tape Archive) is a container format that bundles multiple files into one without inherent compression. When converting GZ to TAR, the tool decompresses the Gzip layer to reveal the underlying TAR archive structure. This process is essential when you have a compressed archive that needs to be accessed or appended to by systems or software that specifically require uncompressed TAR bundles.

The conversion is completely lossless. Since both formats preserve the integrity of the contained files, the original data remains identical after the Gzip layer is removed.

Tips

Check your source GZ file to ensure it actually contains a TAR archive, as some GZ files only compress a single file.
Ensure you have enough disk space for the TAR file, as it will be slightly larger than the compressed GZ version.
Use this tool before running 'tar -xf' if you are unsure if your system supports direct Gzip-decompressed extraction.

Common use cases

Preparing software packages for distribution on legacy systems that do not support Gzip decompression.
Modifying specific files within a TAR archive that was previously compressed for storage.
Standardizing build artifacts in CI/CD pipelines where uncompressed TAR files are required for staging.
