SmartDraw drawings and diagrams (.sdr) can be exported to all kinds of graphics formats, including JPEG format (.jpg, .jpeg). Such sdr to jpg conversion can be done using the program's main File ► Save function that will create a .jpg file from the .sdr file. As far as we know, no other program supports SmartDraw drawings, so you cannot perform this conversion without it.
