Table of file formats supported by WinZip

WinZip can create Zip files (.zip or .zipx), lha/lzh files, and UUencoded files (does not apply to versions earlier than WinZip 12). WinZip can also open and extract from a number of other archive formats.

Archive formats supported by WinZip are listed in the table below. Please note that in cases where the version is listed as ALL, this applies to all currently supported WinZip versions. For a brief description of these archive formats and WinZip's support of them, please see the article Other Archive Support.

Note: IMG support is limited to ISO-type disc image files.

Encoding formats supported:

  • MIME encoding generally uses the Base64 format, but also includes plain/text and quoted-printable formats.
  • The Extension columns list some of the most commonly used filename extensions for files in the various archive and encoding formats. This list, however, is not exhaustive.
