Book Interior KitAnswersKDP activity books
How do I batch convert hundreds of images into a KDP interior?
Short answer: Put the finished images in one folder, name them in print order, choose the KDP setup once, then convert and preview the whole batch before exporting.
Why this matters
High-page-count coloring, activity, and puzzle books are hard to assemble one page at a time. Batch conversion works only if the file order, trim size, bleed mode, and color mode are decided before the PDF is built.
Recommended workflow
- Rename files with padded numbers such as 001.png, 002.png, and 003.png.
- Import the folder into Book Interior Kit.
- Choose trim size, bleed or no bleed, orientation, fit mode, and color mode.
- Preview the full PDF locally and check page order.
- Unlock Pro when you are ready to export without the 10-image free preview limit.
Where Book Interior Kit fits
Book Interior Kit helps with the local file-preparation step for image-based KDP paperback interiors. It is independent software, not an Amazon or KDP official product.
Before publishing
- Use padded filenames for predictable order.
- Preview before export.
- Confirm the final PDF in KDP Previewer.
