How to open JB2 files

Did your computer fail to open a JB2 file? We explain what JB2 files are and recommend software that we know can open or convert your files.

What is a JB2 file?

JB2 files are JBIG2 bitmap files, which you can read more about below.

The JB2 file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a JB2 opener may not be able to open all kinds of JB2 files. In this case, though, we only know of one specific use.
