deflate

file format, compression A compression standard derived

from LZ77; it is reportedly used in zip, gzip, PKZIP,

and png, among others.

Unlike LZW, deflate compression does not use patented

compression algorithms.

Used as a verb to mean to compress (not decompress!) a file

which has been compressed using deflate compression. The

opposite, inflate, means to decompress data which has been

deflated.

Deflate is described in RFC 1951.
