BookIllustrationAI vs ColorBliss
ColorBliss makes coloring pages from text, photos and drawings, and its coloring book generator puts up to 50 of them in one PDF. If you are uploading to Amazon KDP, the questions that decide it are which plan lets you sell, and who turns that PDF into a book Amazon will print.

What ColorBliss says about Amazon KDP
ColorBliss answers the KDP question on its own coloring book generator page. It says you can make coloring books to sell on Artist and Business, and tells you to check your trim size, margins, bleed and image quality against Amazon’s requirements before you publish. Its words: “ColorBliss provides the artwork, but you are responsible for preparing a compliant book for publication.”
That is the gap a KDP publisher fills. The PDF holds your pages and a title page, and the generator page does not mention a trim size, blank backing pages or a cover. BookIllustrationAI exports the interior at the trim size you picked, with 0.125 in bleed and blank backs in place, and makes the front, back and spine of the cover with the spine width worked out from your page count. See the coloring book cover generator for the cover side.

Verdict
On pages per dollar, ColorBliss wins. Artist gives you 1,000 credits a month for $24.75 billed yearly, it converts photos, and its coloring book generator already puts 50 pages into one PDF.
A KDP book needs more than the pages in a PDF. ColorBliss says so itself: the trim size, margins, bleed and a compliant file are yours to prepare, and a cover wrap with the right spine is not on its coloring book generator page.
BookIllustrationAI gives you fewer credits and does those steps for you: $59 once for a 40-page book and its cover, or $39.99 a month. Pick it when the thing you want at the end is a book Amazon will print.
Frequently asked questions
- Can I sell coloring books made with ColorBliss on Amazon KDP?
- Yes, on Artist or Business. ColorBliss’s pricing FAQ gives commercial use to those two plans and calls Starter and Hobby personal use. Artist costs $297 a year ($24.75 a month) or $35 billed monthly.
- Does ColorBliss export a KDP-ready PDF?
- It exports a 300 DPI PDF of your pages with a title page. Its own KDP answer tells you to check trim size, margins and bleed against Amazon’s requirements, and says you are responsible for preparing a compliant book. BookIllustrationAI exports one 300 DPI PDF at your trim size with bleed and blank backs already in place.
- Does ColorBliss make a KDP cover?
- Its coloring book generator page does not mention a cover, a spine width or a back cover. A KDP paperback cover is one wide file holding the back, spine and front, sized from your trim and page count. BookIllustrationAI generates all three together.
- How much does ColorBliss cost?
- As of 10 November 2026: Starter is $84 a year or $9 a month, Hobby $149 or $18, Artist $297 or $35, and Business $997 or $99. They include 250, 500, 1,000 and 5,000 credits a month. A standard page costs 1 credit; a photo conversion costs 3.
- Is ColorBliss cheaper than BookIllustrationAI?
- Per page, yes: Artist includes 1,000 credits a month against 29 on BookIllustrationAI Starter, and its yearly Artist plan works out at $24.75 a month. The difference is what you still have to do after the pages are made: the KDP interior and the cover wrap.
- Can ColorBliss turn photos into coloring pages?
- Yes, on every plan, at 3 credits a photo. BookIllustrationAI does not convert photos: it generates pages from a theme you describe.
