JBIG is a lossless compression file format that was created for the fax machine; it can be used by other image file formats. The files created by JBIG format are smaller compared to G3 and G4 file formats.
A MAT-file holds the variables saved from a MATLAB session: numeric arrays such as matrices and images, text, cell arrays and structs. Files saved with -v7.3 are HDF5 files behind a MATLAB header. Unity and Unreal material files use the .mat extension too, but they are a different format.
