What is a PDB file?
PDB (Palm Database) is a versatile container format originally developed for Palm OS. It was used for various types of data, including eBooks, contacts, and applications.
For eBooks, PDB files were commonly associated with the eReader platform by Palm Digital Media. The format has since faded in popularity, but some readers like Calibre still support it.
How to open PDB files
PDB eBooks can be opened using Calibre, eReader Pro, or legacy Palm devices and emulators. Not all PDB files are eBooks, so tools must match the file's original purpose.
Use AnyConv to convert PDB to EPUB or MOBI formats to improve compatibility with modern readers.
