PeaZip is a free and open-source file manager and file archiver[5] for Microsoft Windows, ReactOS,[6] Linux,[7][8][9] MacOS[10] and BSD[11][12] by Giorgio Tani. It supports its native PEA archive format[13] (supporting compression, multi-volume split, and flexible authenticated encryption and integrity check schemes) and other mainstream formats, with special focus on handling open formats. Version 9.4.0 supported 234 file extensions.

PeaZip is mainly written in Free Pascal, using Lazarus. PeaZip is released under the terms of the GNU Lesser General Public License.

Features

The program has an archive browser interface with search and history features for intuitive navigation of an archive's content, and allows the application of fine-grained multiple exclusion and inclusion filter rules to the archive; an alternative flat archive browsing mode is available.

PeaZip allows users to run extracting and archiving operations automatically if invoked from the command line; the GUI front-end can export the command. It can also create, edit and restore an archive's layout for speeding up archiving or backup operation's definition. The program also supports archive conversion, file splitting and joining, secure file deletion, bytewise file comparison, archive encryption, checksum/hash files, find duplicate files, batch renaming, system benchmarking, random passwords/keyfiles generation, view image thumbnails (multi-threaded on the fly thumbnails generation without saving image cache to the host machine), and integration into the Windows Explorer context menu. The user interface (including icons and color scheme) can be customized.

Versions older than 2.6.1[14] were vulnerable to an improper input validation weakness corrected in following versions.

From version 6.9.2, PeaZip supports editing files inside archives (e.g. open, edit, and save a text file without extracting it), and adding files to the root folder or subfolders of an existing archive.

PeaZip is available for IA-32 and x86-64 as a standalone portable application and as an installable package for Microsoft Windows, Linux[15][16] (DEB, RPM and TGZ, compiled both for GTK2 and Qt widgetset), and BSD (GTK2). It is available also as a PortableApps package (.paf.exe)[17] and for Microsoft's winget Windows Package Manager[18]

In addition to more popular and general-purpose archive formats including 7z, Tar, Zip, PeaZip supports the ZPAQ, PAQ, and LPAQ formats. Although not suitable for general use due to high memory usage and low speed, these formats provide better compression ratios for most data structures.[19][20]

PeaZip supports encryption[21] with AES 256-bit cipher in 7z and ZIP archive formats. In PeaZip's native PEA format, and in FreeArc's ARC format, supported ciphers are AES 256-bit, Blowfish,[22] Twofish[23] 256 and Serpent 256 (in PEA format, all ciphers are used in EAX authenticated encryption mode).

Native archive format

PEA, an acronym for Pack Encrypt Authenticate, is an archive file format. It is a general purpose archiving format supporting compression and multiple volume output. The intention is to offer a flexible security model through Authenticated Encryption providing both privacy and authentication of data, and redundant integrity checks ranging from checksums to cryptographically strong hashes, defining three different levels of communication to control: streams, objects, and volumes.[24][verification needed]

It was developed in conjunction with the PeaZip file archiver. PeaZip and Universal Extractor support the PEA archive format.

Third-party technologies

PeaZip acts as a graphical front-end for numerous third-party open source or royalty-free utilities, including:

Separate plugin (optional)

Most of these utilities can run both in console mode or through a graphical wrapper that allows more user-friendly handling of output information.

Adware

Prior to release 5.3, PeaZip installers for Windows and Win64 (but nor Portable or Linux) were bundled with an OpenCandy advertising module which during installation offered optional installation of third-party software; the official download page provided alternative installers without this module, named 'plain'. Later releases do not have an ad-supported bundle.[citation needed]
