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.

Compression

Tag 259 indicates the image compression scheme, as a coded integer. Some of the defined compression schemes are listed below.

Code Compression scheme
1 uncompressed
2, 32771 1-dimensional CCITT Group 3. Essentially the same as compression code 3, but with different settings. There are no end-of-line markers, and each row is aligned on a byte boundary (or a 2-byte boundary for code 32771).
3 1- or 2-dimensional CCITT Group 3, depending on the value of T4Options bit 0.
4 CCITT Group 4
5 LZW
6, 7 JPEG
8, 32946 DEFLATE
9, 10 JBIG (see TIFF-FX)
32773 PackBits
32809 ThunderScan compression
34661 JBIG
34712 JPEG2000

Related formats

Tag 32932 contains TIFF annotation data.
