Frequently asked questions
Can I convert EPUB books to PDB for my Kindle or Kobo?
Yes. Upload your EPUB ebook and it converts to PDB with chapter structure, cover art, and formatting preserved. Load the PDB onto your Kindle, Kobo, Nook, or any eReader that supports the format.
How to convert EPUB to PDB without losing the table of contents
Chapter navigation, the cover image, and text formatting all carry over during conversion. The PDB has proper chapter links so you can jump between sections on your eReader just like the original EPUB.
Can I convert multiple EPUB ebooks to PDB at once?
Yes. Upload a batch of EPUB files and they are all converted to PDB. Each book downloads separately or as a ZIP, so you can convert an entire library in one session.
Does the text still reflow after converting to PDB?
Yes. PDB keeps text reflowable, so it adapts to any screen size and font setting on your eReader rather than being locked to a fixed page like a PDF.
Which reader is PDB for?
PDB is the PDB format best for its intended use. Convert your EPUB to PDB when your eReader or app opens PDB more reliably, so the whole library works on one device.
What is EPUB?
EPUB is a reflowable ebook format, typically used for Kobo, Apple Books, and Nook. Converting it to PDB produces a file that opens on systems without EPUB support.
