7z is an open archive format that usually achieves noticeably higher compression than ZIP or RAR, thanks to the LZMA and LZMA2 algorithms. It supports AES-256 encryption of both file contents and file names, handles archives up to 16 exabytes, and can split output into volumes. The specification is published openly, with no licensing restrictions on implementing it.
How to open a 7z file?
7z archives are created and read by 7-Zip, which remains the reference application for the format. Once it is present, a 7z archive opens with a double-click.
On macOS, The Unarchiver or Keka handle 7z, and on Linux the p7zip package provides the same functionality from the command line. WinRAR and PeaZip can also extract 7z. Because the strongest compression settings are slow and memory-hungry, very large 7z archives take a while to unpack. You can also convert the file with our 7Z to ZIP tool.

Gzip (GZ) is a compression format built on the DEFLATE algorithm and created as a free replacement for the patent-encumbered compress utility. A key point often missed is that gzip compresses a single file — it is not an archive format and cannot hold a folder on its own. That is why it is normally combined with TAR to produce .tar.gz. Gzip is also what web servers use to compress pages before sending them to your browser.
How to open a GZ file?
On Linux and macOS, run gunzip file.gz in a terminal, or double-click the file in your desktop environment to decompress it in place.
On Windows, use 7-Zip, WinRAR, or PeaZip — all of them recognise GZ. If the file is really a .tar.gz, you may have to extract it twice: once to unwrap the gzip layer and once more to unpack the TAR inside. You can also convert the file with our GZ to ZIP tool.
