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.

Contents

[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
4d 4d 00 55 49 49 55 00 Panasonic RAW/RW2
49 49 bc 01 JPEG XR
49 49 4e 31 NIFF (Navy Image File Format)
4d 4d 43 52 49 49 52 43 DNG camera profile
4d 4d 4f 52 49 49 52 4f Olympus ORF
4d 4d 53 52 49 49 52 53 Olympus ORF
45 50 2a 00 MDI

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
1 uncompressed
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.
3 1- or 2-dimensional CCITT Group 3, depending on the value of T4Options bit 0.
4 CCITT Group 4
5 LZW
6 "Old style" JPEG
7 "New style" JPEG
8 DEFLATE (zlib format)
9, 10 JBIG (refer to TIFF-FX)

32895, 32896, 32897, 32898 IT8CTPAD, IT8LW, IT8MP, IT8BL (refer to TIFF/IT)

34676 SGILOG. 32-bit SGI Log Luminance RLE
34677 SGILOG24. 24-bit SGI Log Luminance packed
34692 (Used by LuraDocument Format.)
34712 JPEG 2000

[edit] Color types

Tag 262 indicates the color type ("photometric interpretation") of the image, as a coded integer. Some of the known color types are listed below.

Code Color type
0 Grayscale or bi-level, white is 0
1 Grayscale or bi-level, black is 0
2 RGB
3 Palette color
5 CMYK
6 YCbCr
8 CIE L*a*b*
9 ICC L*a*b*
10 ITU L*a*b* (refer to TIFF-FX)
32803 CFA (refer to DNG)
32844 CIE Log2(L)
32845 CIE Log2(L) (u',v')
34892 LinearRaw (refer to DNG)

  • Tag 700 contains XMP data.
  • Tag 32932 contains TIFF annotation data.
  • Tag 33723 contains IPTC-IIM data.
  • Tag 34152 is for AFCP.
  • Tag 34377 contains Photoshop Image Resources.
  • Tags 34665 (Exif IFD), 34853 (GPS IFD), and 40965 (Interoperability IFD) point to Exif directories.
  • Tag 34675 contains an ICC profile.
  • Tag 37680: See OLE Property Set.
  • Tag 37724 (ImageSourceData) contains (after a 36-byte signature) a "series of tagged blocks", as described in the Photoshop PSD specification and the Adobe Photoshop TIFF Technical Notes document. In some TIFF files, this data has been observed to use little-endian byte order, with block signatures of "MIB8" instead of the usual "8BIM".
  • Tag 50933 (ExtraCameraProfiles) points to DNG camera profiles.
  • Raw camera formats are often based on TIFF.
