Why Use an AI Book Cover Generator?
Speed, Volume and Creative Clarity for Indie Authors

- Move faster: Go from blank page to several AI book cover options in minutes.
- See the options: Compare genres, palettes and compositions before you commit.
- Arrive with clarity: Start design already knowing what fits your audience.

Why Raw AI Images Get Rejected
Uploading raw AI art straight from an AI book cover generator to KDP usually fails review. What you have is an ingredient, not a finished cover.
- Wrong size / resolution / ratio: eBook ideal 2560×1600px @ 300DPI; most AI outputs are square 1:1 or 4:5 at 72–96DPI.
- Color mode: eBook uses RGB; Paperback PDF requires a print‑safe workflow.
- Typography: Title/subtitle/author need professional hierarchy and genre‑matching fonts.
- Paperback layout: Print needs front + spine + back in a single sheet with correct spine width plus bleed/safe zones.

AI Book Cover Generator — FAQ
Not recommended. Raw AI images rarely match KDP’s technical specs (size, 300DPI, aspect ratio). Use the ideas here, then assemble a proper front/spine/back in the KDP Cover Creator and export a print‑ready PDF.
Text isn’t just a box—it’s typography. KDP Cover Creator offers genre‑matched layouts, hierarchy, and spacing so your title stays readable even at thumbnail size.
Yes—browsing and generating ideas on this page is free and requires no account. To publish a KDP‑ready file, finish your cover in the KDP Cover Creator.
Manually: set an exact canvas (e.g., 2560×1600px, 300DPI, RGB for eBook) and craft typography by hand. Easier: open KDP Cover Creator and export a compliant file in minutes.
No. Export 2560×1600 at ~300DPI in RGB as a high‑quality JPG. Bleed applies to print covers rather than eBooks.
Wrong size/ratio, DPI below 300, wrong color workflow, missing spine, missing safe zone, or incorrect bleed in print covers.
Paperback spine ≈ pages × paper factor (white 0.002252 in/page; cream 0.0025; color 0.002347). Hardcover adds a small constant for the case laminate board.
