Snappy

Snappy is a compression format and program library to implement it, introduced by Google. It is designed for very fast compression and decompression.

Snappy is defined as a raw stream format, plus a higher-level "framing format" that can be used as a file format.

Apple used a variant of Snappy (not quite compatible with its specs) in the IWA serialization format used as part of the iWork format used in Pages, Numbers, and Keynote.

Identification
The framing format begins with bytes.
