Version 9.4.0 supported 234 file extensions.
PeaZip is mainly written in [[Free Pascal]], using [[Lazarus (software)|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 and back end|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 ([[Thread (computing)|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<ref>{{cite web |url=https://nvd.nist.gov/vuln/detail/CVE-2009-2261 |title=CVE-2009-2261 |access-date=2021-01-09 |author=National Vulnerability Database |publisher=[[NIST]]}}</ref> 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<ref>{{cite web |url=https://software.opensuse.org/package/peazip |title=OpenSUSE packages |access-date=2021-01-09 |publisher=[[OpenSUSE]]}}</ref><ref>{{cite web |url=https://repology.org/project/peazip/versions |title=Versions for peazip |access-date=2021-01-09}}</ref> (DEB, RPM and TGZ, compiled both for [[GTK+|GTK2]] and [[Qt (software)|Qt]] widgetset), and BSD (GTK2).

In addition to more popular and general-purpose archive formats including [[7z]], [[Tar (file format)|Tar]], [[Zip (file format)|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.<ref>{{cite web |url=http://prize.hutter1.net/ |title=Hutter Prize |access-date=2020-01-09 |author=Marcus Hutter |date=2020-02-01 |publisher=[[Hutter Prize]]}}</ref><ref>{{cite web |url=http://cs.fit.edu/~mmahoney/compression/text.html |title=Large Text Compression Benchmark |access-date=2008-04-09 |author=Matt Mahoney |date=2008-04-06 |quote=The "better" option chooses best compression (equivalent to gzip -9).}}</ref>
PeaZip supports encryption<ref>{{cite web |url=https://viterbiit.usc.edu/services/knowledgebase/step-step-using-peazip-encrypt/ |title=Step by Step Using PEAZIP to Encrypt |access-date=2020-01-09 |author=USC Viterbi IT |date=2020-10-06 |publisher=[[University of Southern California]] }}</ref> with [[Advanced Encryption Standard|AES]] 256-bit [[Block cipher|cipher]] in 7z and ZIP archive formats.

=== Native archive format ===
'''PEA''', an acronym for '''Pack Encrypt Authenticate''', is an [[Archive formats|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 [[hash function|hashes]], defining three different levels of communication to control: [[Stream (computing)|streams]], [[Object (computer science)|objects]], and volumes.<ref name="pea_help">{{cite book|last=Tani |first=Giorgio |title=PEA |url=https://peazip.github.io/pea_help.pdf |date=2008-03-20 }}{{Verify source|date=May 2010}}</ref>{{Verify source|date=May 2010}}
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 processor (program)|front-end]] for numerous third-party open source or royalty-free utilities, including:
* Igor Pavlov [[7-zip|7z]]<ref>{{cite web |url=https://www.7-zip.org/links.html |title=Links |access-date=2020-01-08 |author=Igor Pavlov |quote=Applications that work with .7z archives}}</ref> executable and Myspace's p7zip, POSIX port of 7z under Linux
* Google [[Brotli]]
* Bulat Ziganshin [[FreeArc]], not to be confused with SEA's ARC
* Matt Mahoney at al [[PAQ]]8, [[ZPAQ]] and LPAQ<ref>{{cite web |url=http://cs.fit.edu/~mmahoney/compression/ |title=Data Compression Programs |access-date=2008-04-09 |author=Matt Mahoney |date=2008-03-09 |quote=PeaZip (Giorgio Tani) is a GUI front end for Windows and Linux that supports the paq8o, lpaq1, and many other compression formats.}}</ref>
* Ilia Muraviev [[QUAD (compressor)|QUAD]], [[BALZ]], and BCM compressors
* GNU strip and [[UPX]]
*Facebook [[Zstandard]]<ref>{{cite web |url=https://facebook.github.io/zstd/ |title=Zstandard |access-date=2020-01-08 |author=Yann Collet |quote=Finally, Peazip is a free multi-platforms archiver by Giorgio Tani with support for Zstandard |publisher=[[Facebook]]}}</ref>
==== Separate plugin (optional) ====
* Marcel Lemke UNACEV2.DLL 2.6.0.0 and UNACE for Linux (royalty-free license from ACE Compression Software); being released under a non-OSI compliant license it is available as separate (free of charge) package on PeaZip Add-ons page, as PeaZip UNACE Plugin.
* Eugene Roshal unrar (royalty-free license from RarLab/Win.Rar GmbH, source available but subject to restrictions to prevent creating a rar compressor); being released under a non-OSI compliant license it is available as a separate free-of-charge) package on PeaZip Add-ons page, as PeaZip UNRAR5 Plugin. This optional plugin provides an alternative unrar engine; however standard PeaZip can extract RAR and RAR5 formats with unrar from 7zip.
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|date=July 2014}}
