This article explains what TGZ, GZ and TAR.GZ are, what they are used for and how to open them. We will also look at how to convert the files in the archive (or the entire archive itself) to another format.

A file with the TGZ or GZ file extension is a Gzip-compressed TAR archive. They are called tarballs and sometimes use a "double" extension such as TAR.GZ, but are usually abbreviated to TGZ or GZ.

Files of this type are typically only seen with software installers on Unix-based operating systems like macOS, but they are also sometimes used for regular data archiving purposes. This means that even if you are a Windows user, you may come across these types of files and want to extract data from them.

TGZ and GZ files can be opened with most popular zip/unzip programs, such as 7-Zip or PeaZip. To do this online, you can use B1 Online Archiver.
