Big-endian TIFF starts with 4D 4D 00 2A ('MM' + 42) instead.
TIFF is a tag-based container that can hold multiple images, layers and arbitrary metadata, favoured in publishing and document scanning. The first two bytes declare byte order — II for little-endian, MM for big-endian — followed by the magic number 42.
Have a file that might be TIFF? Identify it with the File Type Identifier — it reads the magic number locally, nothing is uploaded. Or browse all formats.
