Convert GZ Files Online for Free.

GZ, also known as Gzip, is a compressed archive format commonly used in Unix and Linux systems. It is designed to reduce the size of files for storage and transfer, using the DEFLATE compression algorithm.

The GZ format is typically used for single files, and when multiple files need to be compressed, it is often combined with a tarball (TAR) to create .tar.gz or .tgz files.

GZ files can be opened with built-in tools on Linux and macOS, such as the `gzip` command or `gunzip`. On Windows, you can use programs like 7-Zip, WinRAR, or WinZip to extract GZ files.

For graphical interfaces, file archivers like PeaZip or The Unarchiver (for macOS) also support GZ files. For command-line enthusiasts, tools like `gzip` and `tar` are efficient options.

To create a GZ file, use the `gzip` command on Unix/Linux systems. For example, `gzip filename` will compress a file into `filename.gz`.

If you need to compress multiple files into a single GZ archive, first create a tarball with `tar -cf archive.tar file1 file2`, then compress it using `gzip archive.tar`.

To convert GZ to other formats like ZIP, you can extract the GZ file and then re-compress it using a tool like 7-Zip or WinRAR.
