Definition

The ZIP file format is a popular data compression and archival format.

A ZIP file contains one or more files that have been compressed or stored. The ZIP format was originally designed by Phil Katz for PKZIP.

However, many software utilities other than PKZIP itself are now available to create, modify or open ZIP files, notably WinZip, BOMArchiveHelper, PicoZip, Info-ZIP, WinRAR, IZArc and 7-Zip. ZIP files generally use the file extensions ".zip" or ".ZIP" and the MIME media type application/zip.
