Book Interior Kit / Sample Output
What should a Book Interior Kit preview help you check?
Short answer: the preview should help you confirm page order, trim size, bleed mode, margins, and overall PDF layout before you pay for unlimited export. Free mode is meant for a real 10-image test, not a blind checkout.
A typical test
- Import a folder such as
001.pngthrough120.png. - Choose the same trim size and bleed setting you plan to use in KDP.
- Preview the assembled interior PDF locally on your computer.
- Check that page order, margins, backing pages, and canvas size look right.
- Unlock Pro only when you are ready to export the final page images or interior PDF.
What Pro unlocks
Pro removes the 10-image free batch limit and unlocks export for prepared page images and final interior PDFs. It is a one-time USD 29 license. Your artwork files and generated PDFs are processed locally in version 1.
What it does not promise
Book Interior Kit is independent software and is not affiliated with Amazon or Kindle Direct Publishing. It helps reduce common file-preparation mistakes, but it does not guarantee KDP approval and does not replace reviewing your final upload in KDP Previewer.
