Independent JPEG Group IJG is an informal group that writes and distributes a widely used free library for JPEG image compression. You can find our code and some supporting documentation at http://www.ijg.org/files/, or by FTP at ftp://ftp.uu.net/graphics/jpeg/. If you can't cope with tar.gz-format archives, you may prefer the zip-format release at ftp://ftp.simtel.
