What is zlib.dll?

zlib is a common software library used for data compression. zlib compressed data is typically written with a gzip or a zlib wrapper. zlib is something of a de facto standard, to the point that zlib and DEFLATE are often used interchangeably in standards documents, with thousands of applications relying on it for compression, either directly or indirectly.
