File type: Tagged Image
TIF files are very high-quality image or graphics format which are often used specially for storing images that contain many colors such as digital photographs or pictures. It is short for 'TIFF' which is an image compression algorithm which is a lossless compression and it has support for multiple layers and pages.
These TIFF format files are often saved in an uncompressed lossless format but alternatively they can also incorporate .JPEG or loose compression format.
They also support LZW lossless compression algorithm which reduces the size of the image substantially but does not affect the quality of the image.
