MOBI (Mobipocket) was developed by the French company Mobipocket SA in 2000 and later acquired by Amazon in 2005. It was one of the earliest commercial ebook formats and gained wide adoption on early Kindle devices before Amazon transitioned to their AZW format. MOBI supports DRM, tables of contents, and basic styling. While newer formats have surpassed it, MOBI files remain common in older ebook collections and can still be sideloaded onto Kindle devices via USB or email.
Converting MOBI to PDB uses Calibre's ebook-convert engine to parse the MOBI source and emit a PDB file. 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 Though Palm OS is obsolete, PDB conversion is still used in digital preservation workflows and by collectors of vintage mobile technology.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 MOBI to PDB entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
