For those who need to compress or decompress files, 7-Zip is available for no cost and without restrictions. Here we see 7-Zip in action, depicted by an image. Known as an “archiver,” 7-Zip is a program used to pack multiple files into a smaller space. Creator Igor Pavlov released the software in 1999. 7-Zip can read and write multiple archive formats, including its own 7z format as well as others.
What Is 7-Zip?
The program has a graphical user interface for Windows with shell integration, a command line interface for Windows with the command 7za.exe, and a command line interface for POSIX systems with the name p7zip.
The majority of 7-Zip is licensed under the LGPL-2.1-or-later license, while the unRAR code is licensed under the same license but with a special “unRAR restriction” that forbids developers from using the code to decipher the RAR compression algorithm. There has been preliminary Linux support in upstream rather than the p7zip project since version 21.01 alpha.

7z’s Core Compression Is Based on A Number of Different Algorithms, the Most Popular of Which Are Bzip2, Pp Md, Lzma2, and Lzma.
