PeaZip

PeaZip is a free and open-source cross-platform file compression and management utility built using Lazarus and Free Pascal, with source code hosted on GitHub and SourceForge under the GNU Lesser General Public License. The software ships as Windows installer, portable edition, and Linux packages, supporting creation and extraction of over two hundred archive formats including ZIP, 7Z, RAR, TAR, GZIP, BZIP2, XZ, Zstandard, PAQ, Quad, and BCJ. Notable features include file encryption using AES, Twofish, and Serpent cipher algorithms, secure file deletion with multi-pass overwriting, file integrity verification via hash checksums supporting CRC32, SHA-256, SHA-3, and Whirlpool, archive splitting, file comparison, and duplicate file detection across directories. An advanced search function filters files inside archives by size, date, or content patterns. The tool can export batch operations as command-line scripts or graphical scheduling tasks for automated compression workflows. The project accepts no donations and maintains a strictly free model, reflecting the developer commitment to providing a compression tool with zero commercial interference. For privacy-conscious users and IT administrators deploying free utilities in enterprise environments, this open-source project serves as a transparent and auditable alternative to proprietary compression software.
