deflate compression
deflate/inflate compression
inflate
<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}.
