.tif

High-quality graphics format often used for storing images with many colors, such as digital photos; short for "TIFF;" includes support for layers and multiple pages.

TIFF files can be saved in an uncompressed (lossless) format or may incorporate .JPEG (lossy) compression. They may also use LZW lossless compression, which reduces the TIFF file size, but does not reduce the quality of the image.
