AI Book Cover

Model:
Aspect locked per format (Paperback 1:1.5 for KDP / IngramSpark, Hardcover 1:1.6, Kindle 1:1 square). Title + subtitle + author are rendered by the AI itself — Ideogram v3 keeps them legible. If the rendered text is off, the tool falls back to a client-side canvas overlay so you never walk away empty-handed.
Ideogram v3 strongly recommended — publishing-grade covers need readable titles on the first try.

AI Book Cover — FAQ

Free AI Book Cover Generator designs paperback, hardcover, and Kindle covers from title, subtitle, author, and genre. Aspect is locked per format (paperback 1:1.5, hardcover 1:1.6, square Kindle 1:1). Ideogram v3 is the default premium model because it renders book-cover typography cleanly — title + author legible on the first try.

Paperback 1:1.5 (standard 6 by 9) — matches Amazon KDP / IngramSpark. Hardcover 1:1.6 (6 by 9.5) — slightly taller for hardbacks + library editions. Square Kindle 1:1 — ebook thumbnails where width equals height look best.

Yes with Ideogram v3 or FLUX 1.1 Pro Ultra — these two render typography accurately. Standard SDXL often garbles the title; use it only for concept mockups. If the rendered text is off, the tool can overlay it client-side as a fallback.

Yes. 8 genre presets front-load genre-specific cues: fiction (character-focused), thriller (dark palette + tension), romance (soft palette + couple silhouettes), sci-fi (futuristic + stellar), fantasy (painterly + mystical), non-fiction (typography-first), textbook (academic), self-help (clean + aspirational).

The aspect ratios match KDP + IngramSpark paperback requirements. For print, run the output through our /image/upscaler/ at 2x or 4x to reach the 300-DPI minimum (1800x2700 for 6 by 9 paperback). Ebook covers only need 1600px on the long edge — the native render covers that.

Yes. Book covers generated on Free.ai are yours to use for self-publishing on Amazon KDP, IngramSpark, Apple Books, Kobo, or print. No watermark. The underlying image models are commercially licensed.

The title + subtitle + author fields just drive the rendering — they are YOUR book metadata. Do not use a title that infringes an existing trademark. The generated cover art itself is unique to your run.

BookBrush + DesignCap + 100Covers are template editors — you customize pre-made covers. Free.ai is generative — describe the book and get a unique cover rendered per prompt. For finer typography control, use BookBrush after. For faster ideation + more originality, use us first.

The tool outputs the front cover. For full-wrap covers (front + spine + back for print), design the front here, then extend to wrap in Canva / BookBrush / Photoshop. Full-wrap generation is on the roadmap.

~5,000 tokens on FLUX.1 Schnell, ~67,500 on FLUX 1.1 Pro Ultra, ~101,250 on Ideogram v3 (recommended when title legibility matters). Running 2-4 variants per session gets you the best pick for ~200K tokens total.

No. Generate covers immediately. Signing up doubles your daily pool and saves your drafts.

Yes — POST to /v1/image/generate/ with tool:"image-book-cover". See /api/ for the curl example.
