Pictures can be stored as Digital files by Image Processing. JPEG, TIFF, GIF and BMP are common image formats.

What is JPEG (.jpg)?

JEPG is the abbreviation for Joint Photographic Experts Group. This is the common file type for home picture and internet use. It leaves out information that is little used by the human eye, and compresses the rest. The file sizes are much smaller than TIFF, but with little loss of picture quality. They are easily stored and transmitted.

What is TIFF (.tif)?

The Tagged Image File Format (TIFF) is the preferred format for most graphic designers for editing and printing pictures. There is little or no compression and no loss of detail, but the files can be very large (e.g. 30 megabytes). TIFF can be used in virtually all paint, image-editing, and page-layout programs.

What is GIF (.gif)?

Graphic Interchange Format (GIF) files are good for black and white graphics or pictures with small color ranges, and are often used on Web pages. They use an 8-bit format with 256 colors or scales of gray.

What is BMP (.bmp)?

Microsoft's Bitmap Image Format (BMP) is an uncompressed image format - that is, every pixel is represented by a separate digital number in the picture file. The files are very large, like TIFF files.
