== Metadata tags ==
+
== Identification ==
 +
TIFF files begin with bytes <code>4D 4D 00 2A</code> (big-[[Endianness|endian]]), or <code>49 49 2A 00</code> (little-endian).
  
 +
This does not account for [[BigTIFF]] format, which you may or may not consider to be a kind of TIFF.
 +
 +
=== File signatures ===
 +
Some TIFF-like formats use a different file signature (the first few bytes of the file) to help identify them. Some of the known signatures are listed here.
 +
 +
(For formats lacking a public specification, this table may include a hypothetical signature for a byte order that has not been observed.)

TIFF, formerly known as Tag(ged) Image File Format, is an image format capable of storing multiple high quality images in a single file.

A TIFF image may be uncompressed or use a compression scheme internally. Two of the most widely used compression schemes in TIFF files are lossless, including LZW and, for bitonal images CCITT Group 4, as used for facsimile transmission [fax]. JPEG baseline DCT-based lossy compression is also used.

Several subtypes and extensions of TIFF exist, including TIFF/EP, TIFF/IT, DNG, GeoTIFF, TIFF-FX, and BigTIFF. Multi-image TIFFs may represent sequences of images (such as scanned pages of a document), image tiles, or different versions of the same image, for example Pyramid TIFFs that incorporate images at different resolutions (often tiled). Some software that can read and display a TIFF file may only open the primary image.

TI/A (formerly TIFF/A) is a proposed archival standard based on TIFF (but no longer using its name due to objections by Adobe, which owns the rights to the name TIFF) which is in progress of development.

[edit] Identification

TIFF files begin with bytes 4D 4D 00 2A (big-endian), or 49 49 2A 00 (little-endian).

This does not account for BigTIFF format, which you may or may not consider to be a kind of TIFF.

[edit] File signatures

Some TIFF-like formats use a different file signature (the first few bytes of the file) to help identify them. Some of the known signatures are listed here.

(For formats lacking a public specification, this table may include a hypothetical signature for a byte order that has not been observed.)

Big-endian signature Little-endian signature Format
4d 4d 00 2a 49 49 2a 00 TIFF
4d 4d 00 2b 49 49 2b 00 BigTIFF

49 49 4e 31 NIFF (Navy Image File Format)

Non-TIFF formats that could be mistaken for TIFF include:

[edit] Compression

Tag 259 indicates the image compression scheme, as a coded integer. Some of the known compression schemes are listed below. Some of these are not used in genuine TIFF files, but only in other TIFF-like formats.

Code Compression scheme

2 CCITTRLE. 1-dimensional CCITT Group 3. Essentially the same as code 3, but with different settings. There are no end-of-line markers, and each row is aligned on a byte boundary. See this description from the Encyclopedia of Graphics File Formats.
