ZipGenius is a freeware file archiver developed by Matteo Riso of M.Dev Software for Microsoft Windows. It is capable of handling nearly two dozen file formats, including all the most common formats, as well as password-protect archives and work directly with CD-R/RW drives. It is presented in two editions: standard and suite. While the suite edition includes optional modules of the ZipGenius project (oriented to experts and power-users), the standard setup package simply includes the main ZipGenius application.

ZipGenius was first released as Mr. Zip 98 to a strict group of users, and renamed ZipGenius in March 1998. In April 1999, its first public release was made. ZipGenius's latest release is version 6.3.1.2590 (June 2, 2010; 2 years ago  (2010-06-02)), containing a large number of fixes, the majority of which are bug fixes not visible at first glance.

ZipGenius features include: support for TWAIN devices (scanners and digital cameras), file extraction to CD/DVD burner (only under Windows XP), an FTP client (FTPGenius), and ZGAlbum. ZGAlbum allows users to create slideshows with pictures, which can be loaded from a folder or imported through a TWAIN device.
