TIF/TIFF (Tag Image File Format) is widely and common used lossless image format in all platforms, such as Mac, Windows, Unix. With the ability of storing arbitrary number of bits per pixel and having variety of compression algorithms, TIFF is favored by most people, especially by graphic designers. TIFF supports CMYK, RGB, Lab, indexed color and grayscale with alpha avenue and Bitmap images without alpha avenue. When approving or adding new tags, it can extend TIFF format by using tags. That is, the image information can be stored and arranged. 

ICO is a image file extension for small Windows icon. *.ICO can store more than one images with different sizes or colors. Normally it is 16*16 and 32*32 pixels square with 16 colors. Windows XP or VISTA supports bigger size like 48*48 or 256*256 and 32-bit color depth.

The PNG (Portable Network Graphics) is a method to store images by compressing images with no loss of information. PNG files can store colors with up to 48 bits per pixel and gray scales with up to 16 bits per pixel. Moreover, it can also store an optional alpha channel for transparency. When PNG is used in the connected network, it can correct gamma and color of images automatically. So you can accurately render the images on different display devices.

PPM means portable pixmap file format which is based on ASCII format, is a convenient image file format to save an image in ASCII or BINARY mode and store pixel values up to 24 bits in size. It is consisted of a system of one or more PPM images, Used especially in exchanging graphics files between different platforms, supporting 16 bit RGB and Grayscale images.
