WinZip is a proprietary file archiver and compressor for Windows, OS X, iOS and Android developed by WinZip Computing (formerly Nico Mak Computing). By default, WinZip creates archives in Zip file format but also has various levels of support for other archive formats.
WinZip has a 45-day free evaluation period.
WinZip 1.0 was released in April 1991 as a graphical user interface (GUI) front-end for PKZIP. Earlier in January 1991 Nico Mak Computing released a GUI front-end for OS/2 Presentation Manager called PMZIP. It used OS/2 versions of the PKWARE, Inc. PKZIP and PKUNZIP programs. Originally released on CompuServe, availability of WinZip expanded across major online services, including GEnie, Prodigy and other online services. In 1993, WinZip announced the launch of its official support for customers on the Windows Utility Forum, serving over 100,000 members, providing updates and related information. The freely downloadable WinZip soon found itself included in best-selling Windows computing titles as part of companion disks, including the all-time best-selling Windows 3.0 book, Windows Secrets, by Brian Livingston. By 1994, WinZip had become the official and required compression tool used by system operators on CompuServe for forum file libraries.
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. WinZip is available in standard and professional versions. However, the ability of Windows XP and later versions of Microsoft Windows to open and create .zip files (as "compressed folders") has reduced the need for extra compression software.
- Creation of, addition to, and extraction from ZIP archives.
- Configurable Microsoft Windows Shell integration
- Direct write of ZIP archives to CD/DVD
- Decoding of .b64, .hqx, .uue formats.
- Automation of backup jobs
- Integrated FTP upload
- Email ZIP archives
- Decompression of following archive formats: .bz2, .rar, LHA/LZH (native in 11.2), 7z (12.0).
- Support for ARC and ARJ archives if suitable external programs are installed.
Supported .ZIP archive features 
- 128- and 256-bit key AES encryption in addition to the less secure PKZIP 2.0 encryption method used in earlier versions. The AES implementation, using Brian Gladman's code, was FIPS-197 certified, on March 27, 2003. However, Central Directory Encryption feature is not supported. 
- Beginning with WinZip 9.0, ZIP64 archives are supported, eliminating both the maximum limit of 65,535 members for single archive and the 4-gibibyte size limit on either the archive and each member file.
- Support of additional compression methods: bzip2 (9.0), PPMd (10.0), WavPack (11.0), LZMA (12.0), JPEG (12.0).
- Unicode support to ensure international characters are displayed for filenames in a Zip file. (WinZip prior to 11.2 does not support Unicode characters in filenames. Attempting to add these files to an archive results in the error message "Warning: Could not open for reading: ...")
