  Compression \Com*pres"sion\, n. [L. compressio: cf. F.
     1. The act of compressing, or state of being compressed.
        "Compression of thought." --Johnson.
        [1913 Webster]
     2. (Computers) reduction of the space required for storage
        (of binary data) by an algorithm which converts the data
        to a smaller number of bits while preserving the
        information content. The act of compressing [3].
     Note: Compression may be lossless compression, in which all
           of the information in the original data is preserved,
           and the original data may be recovered in form
           identical to its original form; or lossy compression,
           in which some of the information in the original data
           is lost, and decompression results in a data form
           slightly different from the original. Lossy
           compression is used, for example, to compress audio or
           video recordings, and sometimes images, where the
           slight differences in the original data and the data
           recovered after lossy compression may be
           imperceptable to the human eye or ear. The JPEG
           format is produced by a lossy compression algorithm.

From The Collaborative International Dictionary of English v.0.48 :

  JPEG \JPEG\ n. [Acronym from Joint Picture Experts Group.]
     A standardized format for storing graphic data in binary
     computer files, allowing over 16 million different colors. It
     allows for lossy compression, i. e. the compression of data
     into a form which re-expands into an image close, but not
     identical to the original image. Files stored in this format
     usually carry the extension jpg or jpeg. Compare GIF.

         Joint Photographics Expert Group (org., JTC1, RFC 1521, JPEG)

From The Free On-line Dictionary of Computing (30 December 2018) :

  Joint Photographic Experts Group
      (JPEG) The original name
     of the committee that designed the standard image
     compression algorithm.  JPEG is designed for compressing
     either full-colour or grey-scale digital images of
     "natural", real-world scenes.  It does not work so well on
     non-realistic images, such as cartoons or line drawings.  JPEG
     does not handle compression of black-and-white (1
     bit-per-pixel) images or moving pictures.  Standards for
     compressing those types of images are being worked on by other
     committees, named JBIG and MPEG.
     Filename extension: .jpg, .jpeg.
