What is a .JB2 file?
The .JB2 file extension is used for images that are saved in the JBIG2 Image format. This type of image file is special because it only uses black and white colors to create the picture, which is why it's called a bitonal image. The JBIG2 stands for Joint Bi-level Image Group 2, which is a standard for encoding these black and white images.
One of the key features of the .JB2 file format is that it can compress the size of the images very well, either by reducing the quality a little bit (lossy compression) or without losing any quality at all (lossless compression). This means that .JB2 files can be much smaller than similar black and white images saved in other formats, like those used for fax machines (CCITT Fax Group 4 compression).
If you have a .JB2 file that you want to open and view, there are several programs that can help you with that. Newera Graphics Converter Pro and XnViewMP are two examples of software that can open .JB2 files. Both of these programs support viewing and possibly converting .JB2 files into other image formats. Another program that can work with .JB2 files is AMBWare Image Size Reducer Pro, which, as the name suggests, can also help reduce the size of images, including those in the .JB2 format.
In summary, if you come across a .JB2 file, it's a highly compressed black and white image. To open, view, or convert it, you can use programs like Newera Graphics Converter Pro, XnViewMP, or AMBWare Image Size Reducer Pro.
