About the PDB Format

PDB (Palm Database) is a legacy ebook format originally developed for Palm OS handheld devices in the late 1990s. Used by Palm Digital Media (formerly Peanut Press) and later eReader, PDB files stored ebooks as compressed text databases optimized for the limited storage and processing power of Palm PDAs. The format supported basic text formatting, chapter navigation, bookmarks, and simple image embedding.

With the discontinuation of Palm OS devices and the rise of modern eReaders and smartphones, PDB has become an obsolete format. Barnes & Noble acquired the eReader platform and migrated its catalog to EPUB for the Nook ecosystem. Ebooks stored in PDB format can no longer be read on current devices without conversion. Converting PDB files to EPUB, PDF, or MOBI rescues these legacy ebooks for use on modern eReaders, tablets, and reading apps, preserving the text content and basic structure of the original files.
