What is a GZ file extension?

The GZ file format is commonly used as a compression format for Linux and Unix operating systems. So as a Windows or Mac user, you might not be entirely familiar with what the GZ file format is.

Jean-loup Gailly and Mark Adler created the GZ file extension in the early 90s to improve compression in Unix.

The GZ file format later found use in Linux as well. GZ shares many traits with the ZIP file format and is widely used in the same sense – compressing files.

One downside to GZ is that it can’t compress multiple files into one. However, the GZ file format is often combined with TAR archives to archive multiple files. Unfortunately, this combination does not support compression.

What are GZ files used for?

Much like a ZIP file, the GZ file format is used for file compression. And with the GZ file extension, it’s possible to store single files.

When using the GZ file extension, useful information such as the original file name and timestamps remain intact. This can be very handy as compressed files may lose their timestamp when transferred.

Other than compressing local files, GZ compression is often used to compress elements of web pages to speed up page loading. This is important, as an increase in web page loading can reduce bounce rate (visitors leaving your site) by up to 32%.

  3. Click “Add to Zip”.
  4. In the actions panel, click “Save as”.
  5. Choose any local, network or cloud location where you wish to save your new ZIP file.
  6. You may also choose to email it, share it in an instant message or via supported social media platforms.

  2. Right-click the folder and select “Add/Move to ZIP file”.

Converting GZ Files

Since your GZ file might not be compatible with the software you intend to use, it’s a good idea to convert it into a more accessible compression format.

WinZip allows you to convert any GZ file into a ZIP file. Giving you all the benefits of the GZ file format with added accessibility and ease of use.

Follow this detailed guide to convert your GZ file into ZIP with WinZip:

  5. Choose any local, network or cloud location where you wish to save your new ZIP file.
  6. You may also choose to email it, share it in an instant message or via supported social media platforms.

Password Protecting GZ Files

Having a password protected GZ file is crucial if you're storing or sharing sensitive data. By encrypting your GZ file, you can set your own password that stays the same whether you’re adding or removing files from the archive folder or sending the file to other people.

However, WinZip can only be used to encrypt ZIP files, which means that your GZ file has to be converted first. To do this, please follow the steps listed above.

Once you’ve converted your GZ file into a ZIP file, follow these steps to encrypt it.

  1. Open WinZip.
  2. Click “Encrypt” in the actions panel.”
  3. Drag and drop the file you wish to encrypt into the center and enter a password when the prompt appears.
  4. Click “Options” in the action panel to choose your encryption settings and click save.

Done! With WinZip, password protecting your GZ files has never been easier.
