Overview

BigTIFF is a TIFF-like image file format, which supports larger files and data structures than does TIFF. It is logically almost identical to TIFF, though it is not compatible with it.

Identification

Files begin with 49 49 2B 00 08 00 00 00 (little-endian BigTIFF), or 4D 4D 00 2B 00 08 00 00 (big-endian BigTIFF).
