It contains cjpeg, djpeg, jpegtran, rdjpgcom and wrjpgcom. Cjpeg compresses an image file into JPEG format. Djpeg decompresses a JPEG file into a regular image file. Jpegtran can perform various useful transformations on JPEG files. Rdjpgcom displays any text comments included in a JPEG file. Wrjpgcom inserts text comments into a JPEG file.
