ตัวแปลงไฟล์ออนไลน์ฟรี LRF เป็น PDB

Is a format developed by Sony for its proprietary Sony Reader devices. Files in this format may contain text and images. The format is XML-based.

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 Today it has become obsolete and has been replaced by more flexible formats with DRM protection.
