Definitions for "Joint Photographic Experts Group"
Keywords:  jpeg, jpg, lossy, photographs, compress
An image compression algorithm that often reduces the size of bitmapped images by a factor of 10 or more with little or no discernible image degradation. JPEG compression works by filtering out image high frequency information, to reduce the volume of data and then compressing the resulting data with a lossless compression algorithm. Low frequency in formation does more to define the characteristics of an image, so losing some high frequency information doesn’t necessarily affect the image quality.
file format for high-quality images often used on the Web
Joint photographic experts group or .JPEG or .JPG for short is a file format used for color images. This format retains a high degree of color while requiring less storage space than needed for other file formats. Uncompressed JPEG files can be used for high-quality printing.
