You can create a zip easily on all major OSes with drag'n'drop. Windows supports it IIRC from Win 98 SE and up, a standard Linux by the tools the desktop installs (for KDE, it once was Ark), and MacOS also delivers ZIP out of the box. For ZIP, there are even built-in PHP functions to handle it. 7zip is, though open source, requiring third-party plugins, both for the OS and servers, and 7zip is not really widespread. RAR and ZIP are the dominant formats in cross-platform data exchange.
