How do I make a KDP coloring book PDF from images?
Short answer: Sort the artwork files, choose the KDP trim size, decide bleed or no bleed, place each image on a consistent 300 DPI page canvas, add optional backing pages, preview the PDF, and export only after checking page order, margins, and KDP Previewer.
Why this causes KDP problems
Coloring book creators often have a folder of finished PNG or JPG artwork, but the images may have inconsistent dimensions, unclear file order, or the wrong bleed setup. Turning that folder directly into a PDF can create hidden page-size and order problems.
Recommended workflow
- Rename artwork files with leading zeros.
- Choose the exact KDP trim size.
- Choose bleed or no bleed.
- Use a consistent 300 DPI page canvas.
- Add backing pages only if they fit the book design.
- Preview the PDF and then review it in KDP Previewer.
Where Book Interior Kit fits
Book Interior Kit imports artwork folders, sorts filenames, applies KDP page settings, creates a local PDF preview, and unlocks export with Pro. It is meant for finished artwork, not for drawing the artwork itself.
What to check before publishing
- Every page appears in the intended order.
- All artwork pages use the same trim and bleed settings.
- Backing pages, if used, follow the same page size as artwork pages.
- The final PDF has no crop marks, annotations, hidden objects, or watermarks.
- The final PDF is reviewed in KDP Previewer.
