Convert PDB Files Online for Free.

PDB (Palm Database) is a generic container format originally developed for Palm OS applications and data, later adopted for ebooks on Palm devices. Various ebook formats including Mobipocket, eReader, and PalmDOC use PDB as their container structure, each with different internal formatting.

PDB files offer simple formatting with efficient compression, making them suitable for the limited storage capacity of early mobile devices. Though considered legacy today, PDB remains important for accessing older ebook collections and publications from the early mobile computing era. Supported extension is .pdb.

How to open PDB?

Opening PDB files depends on the specific format contained within the PDB container. For eReader and PalmDOC formats, applications like eReader (formerly Palm Reader) can display the content. Mobipocket-formatted PDB files can be opened with Mobipocket Reader or Amazon Kindle applications.

For modern devices, ebook management software like Calibre with appropriate plugins can open various PDB formats after identifying the specific internal format. Due to the format's age and diversity, conversion to contemporary formats like EPUB or MOBI is often the most reliable approach for accessing PDB content.
