How do I convert KDP images into an interior PDF?
Short answer: Start with ordered image files, choose the same trim size and bleed setting you will use in KDP, place each image on a consistent 300 DPI page canvas, preview the assembled PDF, then export the final interior PDF only after the page order and margins look correct.
Where Book Interior Kit fits
Book Interior Kit imports an artwork folder, sorts the files, applies KDP page settings, builds a local PDF preview, and unlocks image or PDF export with Pro. The free version lets authors process 10 images and preview the PDF before buying.
What to check before uploading
- Trim size matches the book setup in KDP.
- Bleed or no-bleed mode matches the KDP choice.
- Pages appear in the expected order.
- Artwork is sharp enough for print.
- Final PDF is reviewed in KDP Previewer.
Book Interior Kit is independent software, is not affiliated with Amazon or KDP, and does not guarantee KDP approval, but it helps reduce common file-preparation mistakes before the final review.
