zlib format is a variant of the DEFLATE compressed data format. It adds a lightweight container, a small amount of configurability, and error checking.
zlib is also the name of a software library that supports the zlib format, and other formats related to DEFLATE.
There are many formats and protocols that use, or may use, zlib format. A notable example is PNG.
