List of the Top 6 File Compression Software for Linux in 2025

PeaZip serves as a robust and free file archiving application that enables users to access and extract content from various formats, including RAR, TAR, and ZIP. This tool is designed to work on multiple operating systems, such as Linux (both x86_64 and x86), Darwin, macOS (supporting aarch64 M1 and Intel), MS Windows, ReactOS, and Wine, with experimental functionality for Linux ARM and aarch64. Built upon open-source technology sourced from 7-Zip/p7zip, Facebook's Zstandard compressor, FreeArc, Google Brotli, the PAQ compression family, and the secure file archiving and encryption PEA project, it integrates a range of other free software solutions as well. PeaZip distinguishes itself as a cross-platform application, offering a consistent graphical user interface across Linux, macOS, and Windows, along with a portable version for convenience. Supporting over 200 archive formats, it features advanced compression capabilities such as 7Z and ZPAQ, and faster alternatives like Brotli and Zstandard, enabling seamless conversion among different archive types. Furthermore, its intuitive interface caters to users of all skill levels, enhancing accessibility and usability for a broad audience, making it a preferred choice for file compression needs.

GNU Gzip is a popular data compression utility that was initially created by Jean-loup Gailly for the GNU project, while the component for decompressing was developed by Mark Adler. This tool was introduced as a substitute for the older compress program, which faced limitations due to the Unisys and IBM patents on the LZW algorithm, rendering it impractical for many users. In addition to its status as a viable alternative, gzip boasts enhanced compression efficiency, making it even more appealing. Users can obtain stable source releases from the main GNU download server (accessible via HTTPS, HTTP, and FTP) as well as from various mirrors, with a suggestion to prefer mirrors whenever feasible. Gzip applies Lempel-Ziv coding, specifically LZ77, to compress the designated files. Generally, files are converted to include a ‘.gz’ extension, while their original ownership modes, access rights, and modification timestamps remain intact. However, for certain operating systems like MSDOS, OS/2 FAT, and Atari, the common extension used is ‘z’. When no specific files are indicated for compression, the utility can process data from standard input and output the results accordingly, which highlights its adaptability across different environments. This adaptability not only increases its utility but also solidifies gzip's reputation as an essential tool for efficient data handling and management tasks.

With each year that goes by, there is a notable increase in the amount of data that is stored and exchanged around the world. The costs tied to data storage and transmission are climbing, whether organizations opt for on-premises solutions or cloud-based services. To effectively manage expenses and allocate resources wisely, there is a significant need for a flexible and powerful data compression solution. Nearly three decades after the emergence of the ZIP file format, PKZIP continues to set the standard in data compression and file management. By leveraging PKZIP, companies can realize file compression rates as high as 95%, which not only reduces storage costs but also greatly speeds up file transfers.
