PDB eBook Format

PDB Converter

The PDB format name is short for Palm Desktop Database. Palm was a popular personal desktop assistant (PDA) brand from the mid-1990s up until 2011. PDAs like Palm and BlackBerry were a precursor to smartphones. There were several programs on Palm devices which used the PDB format, including word processors, database or spreadsheet applications, and the Palm ereaders. You can find out what type of program a PDB was created with by opening the file in a text editor.

As smartphones have now replaced PDAs, people tend to use these or a separate ereader for reading ebooks. The PDB format also didn’t have digital rights management (DRM) for authors and publishers to copy-protect their work. While Palm devices are no longer being sold, you can still get the Palm Desktop application for Windows. Other ways of viewing PDB files include with Calibre’s ereader software, or with the XnViewMP graphics application.

EPUB eBook Format

EPUB Converter

EPUB is the standard open-source format for ebooks. EPUB is short for ‘electronic publication’. The format was developed in the mid-late 2000s by the International Digital Publishing Forum and is an alternative to formats like AZW, developed for the Kindle. EPUB files can be viewed on a wide range of e-readers and digital reading apps, including NOOK, Apple Books, Okular and Calibre. Amazon announced in 2022 that new Kindle models would also support EPUB files.

The EPUB standard is now maintained by a World Wide Web Consortium (W3C) working group. The EPUB format comprises three open standards – one defining content markup, one describing the ebook structure, and one packaging all the files into a compressed format. EPUB files normally include an index page for navigation, and accessibility features to adjust text size or allow for text-to-speech. EPUB also has the potential to include interactivity, accessible image, video, or audio elements.
