'''WinZip''' is a [[trialware]] [[file archiver]] and [[data compression|compressor]] for [[Microsoft Windows]], [[macOS]], [[iOS]] and [[Android (operating system)|Android]]. It is developed by WinZip Computing (formerly Nico Mak Computing), which is owned by [[Alludo]]. The program can create archives in [[ZIP (file format)|Zip]] file format, unpack some other archive file formats and it also has various tools for system integration.

==History==
WinZip 1.0 was released in April 1991 as a [[graphical user interface]] (GUI) front-end for [[PKZIP]].<ref name="moran2000">{{cite news |last1=Moran |first1=John |title=WinZip: A Proven Winner |url=https://www.newspapers.com/clip/77728224/winzip-a-proven-winner/ |access-date=15 May 2021 |work=[[Hartford Courant]] |publisher=[[Tribune Publishing]] |date=4 May 2000 |archive-url=https://web.archive.org/web/20210515132714/https://www.newspapers.com/clip/77728224/winzip-a-proven-winner/ |archive-date=15 May 2021 |location=[[Hartford, Connecticut]] |page=47 |url-status=live |via=[[Newspapers.com]] }}</ref> The ZIP file archive format (ZIP) was originally invented for [[MS-DOS]] in 1989 by [[Phil Katz]].<ref>[http://www.smartcomputing.com/editorial/dictionary/detail.asp?&searchtype=0&DicID=19632&RefType=Encyclopedia|Smart Computing Encyclopedia] - Article about WinZip</ref>

WinZip 5.0 implemented built-in PKZIP routines and code from [[Info-Zip]] and so no longer needed the PKZIP executable.<ref>https://kb.winzip.com/130360/</ref>

[[File:WinZip icon.png|thumb|Former WinZip icon]]
From version 6.0 until version 9.0, registered users could download the newest versions of the software, enter their original registration information or install over the top of their existing registered version, and thereby obtain a free upgrade. This upgrade scheme was discontinued as of version 10.0.<ref>{{cite web|url=http://www.winzip.com/xregno.htm|title=Why is my registration code not working in WinZip 12?|date=October 30, 2013}}</ref>

On May 2, 2006, WinZip Computing was acquired by [[Corel Corporation]] using the proceeds from its [[initial public offering]].<ref name=":0">{{cite web|archive-url=https://web.archive.org/web/20070312070118/http://investor.corel.com/releasedetail.cfm?ReleaseID=194952 | url=http://investor.corel.com/releasedetail.cfm?ReleaseID=194952 | archive-date=March 12, 2007|title=Corel Corporation Acquires WinZip Computing; World's Leading Aftermarket Compression Utility Joins Award-Winning Software Portfolio}}</ref><ref>{{Cite web|last=|date=2006-04-04|title=Corel to return to public life merged with WinZip|url=https://techmonitor.ai/techonology/corel_to_return_to_public_life_merged_with_winzip|access-date=2021-04-25|website=Tech Monitor|language=en-US}}</ref>

In 2010, WinZip went multi-platform with the release of WinZip 1.0 for Mac OS X (November 16, 2010). This initial release was compatible with [[Intel]] Macs and could be run on v10.5 'Leopard.'<ref>[http://www.marketwire.com/press-release/WinZip-Compression-Encryption-Email-Attachment-Optimization-Coming-New-Platforms-1354285.htm WinZip Compression, Encryption and Email Attachment Optimization Coming to New Platforms - The World's Most Trusted Zip Utility Now Available for the Mac].
