IMPLEMENTATION

Viewers responsible for this format

zlib wraps DEFLATE data with a small header and Adler-32 checksum. Anyfile distinguishes that wrapper from raw DEFLATE and reports bounded stream metadata locally.

Common question

Is zlib the same as gzip?

Both can carry DEFLATE data, but their headers, trailers and intended metadata differ.
