Why it matters
300 dpi, really
The pixels are there (a 1024 px picture is enlarged to 2250 px for an 8.5 x 11 page with half-inch margins) and the file says 300 dpi, so KDP, Canva, Word and InDesign place it at the right size instead of reading 72 dpi.
Clean coloring pages
AI line art comes with grey fuzz, a cream paper tone and speckle. Cleaning makes the paper pure white and the lines pure black, with a soft edge so curves stay smooth, and clears the specks.
Batch, in the browser
Fifty pictures at once, converted on your own computer. Nothing is sent anywhere, and nothing waits in a queue.
Questions
JPG or PNG for KDP?
JPG for colour photographs and covers (smaller files); PNG for line art and coloring pages (no JPEG blotches round the lines).
Does KDP accept WEBP images?
No. KDP takes JPG, PNG and TIFF for images in a manuscript, and a PDF for a print interior. Convert WEBP to PNG (best for line art and coloring pages) or JPG (smaller, fine for photos) first.
Why are my AI images blurry or rejected for low resolution?
Most generators make 1024 px pictures, which is only 3.4 in at 300 dpi. Printed on an 8.5 x 11 page they are stretched to about 120 dpi. This page enlarges them to the full page at 300 dpi with a Lanczos filter; clean line art prints crisp at that size.
PNG or JPG for a coloring book?
PNG. Coloring pages are black lines on white, and PNG keeps the lines sharp with no JPEG blotches round them. JPG is fine for full-colour covers and photos.
What size should a KDP coloring page image be?
2550 x 3300 px for a full 8.5 x 11 in page at 300 dpi (2625 x 3375 px with bleed). With half-inch margins the art itself is up to 2250 x 3000 px.
Can I make the whole book here?
Download one PDF with a picture a page at your trim size, or open the <a href="kdp-coloring-pages.html">KDP coloring page maker</a> for blank backs and a Word copy. The cover is made in the <a href="kdp-cover-converter.html">KDP cover converter</a>.
Can I sell AI coloring books on KDP?
KDP allows AI-generated content, but asks you to say so when you publish, and the pictures must not copy characters or artwork you do not have the rights to.
