When EPUB is the right output
EPUB is the open ebook standard, reflows text, supports tables of contents and metadata, works on every e-reader except Kindle (which uses MOBI/AZW3 natively but converts EPUB on upload). Convert to EPUB when publishing to Apple Books, Kobo, Google Play Books, or shipping direct-to-reader PDFs / DOCX manuscripts.
Frequently asked questions
Can I convert PDB books to EPUB for my Kindle or Kobo?
Yes. Upload your PDB ebook and it converts to EPUB with chapter structure, cover art, and formatting preserved. Load the EPUB onto your Kindle, Kobo, Nook, or any eReader that supports the format.
How to convert PDB to EPUB without losing the table of contents
Chapter navigation, the cover image, and text formatting all carry over during conversion. The EPUB has proper chapter links so you can jump between sections on your eReader just like the original PDB.
Can I convert multiple PDB ebooks to EPUB at once?
Yes. Upload a batch of PDB files and they are all converted to EPUB. 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 EPUB?
Yes. EPUB 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 EPUB for?
EPUB is a reflowable ebook format best for Kobo, Apple Books, and Nook. Convert your PDB to EPUB when your eReader or app opens EPUB more reliably, so the whole library works on one device.
