TIFF was chosen as the native format for raster graphics in the [[NeXTstep]] operating system, and this TIFF support carried over into [[Mac OS X]]. Adobe Systems, which acquired the [[PageMaker]] publishing program from Aldus, now controls the TIFF specification, although it has not had a major update since 1992 (several technical notes have been published with minor extensions to the format).

For example, TIFF can be used as a container for JPEG and [[Run-length encoding|RLE (run-length encoding)]] compressed images. A TIFF file can also include a [[vector (spatial)|vector]]-based [[Clipping path]] (an outline that crops or frames the main image). The ability to store image data in a [[Lossless data compression|lossless]] format makes TIFF files a useful method for archiving images. Unlike standard JPEG, TIFF files can be edited and resaved without suffering a compression loss. Other TIFF file options include multiple layers or pages.

As a result the [[lowest common denominator]] soon became "the" TIFF, and even today the vast majority of TIFF files, and the code that reads them, are based on a simple 32-bit uncompressed image.
TIFF has an option to use [[LZW]] compression, a [[lossless data compression]] technique for reducing file size. Until recently, the use of this option was limited because the LZW technique was the subject of several patents. However, these patents have now all expired.
TIFF format is standard in [[document imaging]] and [[document management]] systems. In this environment it is normally used with [[ITU-T|CCITT]] Group IV 2D compression, which supports black-and-white (also called bitonal or monochrome) images. In high-volume environments, documents are typically scanned in black and white (rather than color or grayscale) to conserve storage capacity. An average A4 scan produces 30 kilobytes (KB) of data at 200 [[ppi]] (pixels per inch resolution) and 50 KB of data at 300 ppi. 300 ppi is far more common than 200 ppi.
TIFF biçimi birden fazla sayfayı desteklediği için, çok sayfalı dokümanlar ayrı ayrı dosyalar yerine tek bir TIFF dosyası olarak kaydedilebilir.
Because TIFF format supports multiple pages, multi-page documents can be saved as single TIFF files rather than as a series of files for each scanned page.
== ExploitsÜstünlükleri ==
The TIFF [[file format]] is unusual in comparison to other image formats, in that it is composed of small descriptor blocks containing offsets into the file which point to the actual pixel image data (composed of bands of pixel rows). This means that incorrect offset values can cause programs to attempt to read erroneous portions of the file or attempt to read past the physical [[end of file]]. Like most other image file formats, improperly encoded packet or line lengths within the file can cause poorly written rendering programs to [[buffer overflow|overflow their internal buffers]]. Properly written image rendering programs generally avoid such pitfalls.
