ตัวแปลงไฟล์ออนไลน์ฟรี PDB เป็น JBIG

This format was used for storing databases on the Pegasus and Palm PDA devices. Besides images, PDB allowed you to store tables, maps, e-books, and other data in a structured way. Today it has become obsolete and has been replaced by more flexible formats with DRM protection.

JBIG is a standard for lossless compression of image formats. Despite the fact that it was initially developed for fax machines, it can be easily used for other types of images. Files saved in the JBIG format are smaller in comparison with the other industry standard formats like G3 or G4.
