TIFF is a computer file format for storing raster graphics images, popular among graphic artists, the publishing industry, and both amateur and professional photographers in general. The format was originally created by the company Aldus for use in desktop publishing. When Adobe Systems Acquired Aldus, they published Version 6 (1993) of the TIFF specification which dropped the Microsoft reference. TIFF remains a published specification under the control of Adobe Systems. The TIFF format is widely supported by image-manipulation applications, by publishing and page layout applications, and by scanning, faxing, word processing, optical character recognition and other applications.
In computing, JPEG (seen most often with the .jpg or.jpeg filename extension) is a commonly used method of lossy compressionfor digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web.
