JBG Converter

JBG is an image format used for grayscale, black and white, and color images. It is also called JGB1, and it was originally developed to compress images for faxes. But it works well for any images you must compress first before sending or downloading, making it a favorite in the early days of the Internet. JBG files can be opened by Newera Graphics Converter Pro or XnViewMP, both Windows programs. For Mac, you can use Newera Graphics or XnViewMP, but a third program, ToyViewer, is also available for opening JBG files. The JBG has been replaced by JBIG2 or JB2 files, which are more efficient for bi-level images.
