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.
[edit] Identification
The framing format begins with bytes 0xff 0x06 0x00 0x00 's' 'N' 'a' 'P' 'p' 'Y'.
