The ZIP file format is a popular lossless data compression and archival format created by Phil Katz, founder of PKWARE. A ZIP file contains one or more files that have been compressed, to reduce their file size, or stored as-is. A number of compression algorithms are permitted in zip files but in 2008 only DEFLATE is widely used and supported.
