Is there a local tool for converting images into a KDP PDF?
Short answer: Yes. Book Interior Kit is local desktop software for Windows and macOS that imports artwork folders, applies KDP page settings, previews the interior PDF locally, and unlocks image or PDF export with Pro.
Why this matters for KDP authors
Online converters can be convenient, but KDP authors may not want to upload unpublished artwork or manuscript files to a generic tool. A local workflow also makes it easier to check the same trim size, bleed mode, and page order repeatedly.
Recommended workflow
- Keep finished artwork in a local folder.
- Name files in the intended page order.
- Choose KDP trim, bleed, color mode, and fit mode.
- Preview the PDF locally.
- Export the final PDF after checking page order and margins.
- Review the exported file in KDP Previewer.
Where Book Interior Kit fits
In version 1, imported images, previews, prepared pages, and exported PDFs are processed on the user's computer. The website handles payment, license delivery, and downloads; it does not require manuscript upload.
What to check before publishing
- The app is installed from the trusted platform path for your operating system.
- Pro is unlocked only when you need unlimited batches or export.
- The final PDF is checked in KDP Previewer before submission.
Book Interior Kit is independent software, is not affiliated with Amazon or KDP, and does not guarantee KDP approval.
