A compression format designed to compress either full-color or gray-scale digital images.
A joint venture of the CCIT and International Organization for Standardization (ISO) that developed a standard for compressing gray-scale or color still images.
A graphics file format developed by the ISO. JPEG files are more useful when the image contains a large color palette while the GIF format is more suited to a smaller number of colors. The compression algorithm for JPEG is a lossy one so image resolution is lost as the file is compressed; greater compression leads to greater loss.
