What is 7-Zip?
7-Zip is a free, open-source file archiver that is designed for high compression ratios and handling various compression formats. Developed by Igor Pavlov, it was first released in 1999, and since then, it has gained widespread popularity due to its reliability and performance. 7-Zip is available for Windows, Linux, and macOS operating systems, although the native version is primarily optimized for Windows.
The program uses its own compression format called 7z, but it is capable of handling other formats like ZIP, RAR, TAR, GZ, and ISO. 7-Zip offers excellent compression ratios, particularly with its own 7z format, which often outperforms other formats like ZIP and RAR.
Key Features of 7-Zip
Before diving into how 7-Zip works, let’s explore its standout features that make it a go-to tool for file compression and extraction.
