EPUB (Electronic Publication) is the most widely adopted open standard for digital books, developed by the International Digital Publishing Forum (IDPF). It packages text, images, fonts, and metadata into a single ZIP-based container that reflows to fit any screen size. EPUB is supported natively on iOS, Android, Kobo, Nook, and virtually every major e-reading platform except Amazon Kindle. Its open nature makes it the preferred distribution format for publishers, libraries, and academic institutions worldwide.
Converting EPUB to PDB transforms the structured markup of EPUB into the PDB format while preserving chapter hierarchy and formatting. Our conversion service uses Calibre, the gold-standard open-source ebook management tool, ensuring that text encoding, chapter markers, and embedded assets are faithfully transferred. The converted PDB file retains the original book's content and structure for use on compatible devices.
PDB (Palm Database) is the native ebook format for Palm OS devices and eReader applications. Converting to PDB allows content to be read on Palm PDAs, Treo smartphones, and any device running the eReader application. Though Palm OS is obsolete, PDB conversion is still used in digital preservation workflows and by collectors of vintage mobile technology. The compact PDB format is also supported by several modern multi-format e-reader apps.
PDB is a legacy format primarily for specific historical hardware. Verify your target device supports PDB before converting. For modern devices, EPUB or MOBI are better choices. Our conversion engine processes EPUB to PDB entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
