.TIFF File Extension Reference
TIFF is a flexible tagged-image container used for scans, publishing, photography, and scientific or medical imagery. It can store multiple pages, high bit depths, color profiles, alpha channels, and several compression methods including uncompressed, LZW, Deflate, and JPEG. Compatibility depends on the tags and compression used by the producing application.

What is a .TIFF File? (Technical Definition & Architecture)
TIFF is a flexible tagged-image container used for scans, publishing, photography, and scientific or medical imagery. It can store multiple pages, high bit depths, color profiles, alpha channels, and several compression methods including uncompressed, LZW, Deflate, and JPEG. Compatibility depends on the tags and compression used by the producing application.
Optimized raster or vector algorithms designed for digital rendering and photo encoding.
Encapsulates color matrices preserving natural contrast and tonal distribution.
Enables layered compositing, icon cutouts, and transparent website assets.
TIFF Binary Structure & Header Specifications
The .TIFF format organizes data into validated sequential or hierarchical byte structures. Inspecting the header offset reveals the magic byte sequence 49 49 2A 00 (Little Endian) or 4D 4D 00 2A (Big Endian).
- File Signature (Magic Bytes): 49 49 2A 00 (Little Endian) or 4D 4D 00 2A (Big Endian)
- MIME Content-Type: image/tiff
- Payload Structure: Optimized data stream with metadata headers and checksum records.
- Safety Classification: Low Risk – Safe standard image container format.
