DVDFab is a dedicated software for DVD ripping and conversion. It has some options for Blu-ray discs, but not to create image files from Blu-ray discs. You can use it to rip the movies to .mp4 format, or to copy the main movies from Blu-ray discs without all the menus and additional bonus material. If you need to know more about the software's conversion capabilities please go to DVDFab's website.
