Frequently Asked Questions

Common self-publishing sizes are built in — 6×9, 5.5×8.5, 8.5×11, and more — and custom trim sizes are also accepted. Enter your trim size, page count, and paper stock and the tool calculates the exact spine width, bleed, and safety zones for each printer automatically.

Spine width is a function of page count and paper stock (white paper, cream paper, standard color, or premium color). KDP, IngramSpark, and Lulu each use slightly different spine-width formulas, so providing accurate specs lets us produce a separate print-ready file for each that passes preflight.

Yes. Upload an existing ebook cover (JPEG or PNG) and BookCovers.pro will build the matching spine and back panel at the exact print dimensions for KDP, IngramSpark, and Lulu. Your front image is preserved as-is; spine and back are generated programmatically.

Enter your title, subtitle, author name, back-cover description, and optional style notes. You can also choose from 16 image-style presets (Minimalist, Painterly, Dark Cinematic, Retro, Surreal, 3D Render, and more) and upload up to four reference images — a headshot, a style reference, an object or setting — to guide the AI. Free accounts can generate up to three AI covers per day; once you have any credit balance, AI generations and refinements are unlimited. You can refine or regenerate the cover as many times as you like before spending a credit to download.

Free accounts can generate or refine AI covers up to three times per day at no cost. Once you have a credit balance (any pack), AI generations and refinements are unlimited until you are ready to download. A credit is only spent when you click to download the final print-ready bundle — previewing, iterating, changing text, or regenerating the art never costs a credit.

The audiobook cover is a 1:1 square version of your front cover, with title and author name preserved, optimized for ACX, Findaway Voices, and other audiobook platforms. After purchasing a credit and downloading your bundle, click 'Generate audiobook cover' — it is included at no extra charge.

Yes. Every credit bundle includes hardcover case-laminate PDFs for both KDP and IngramSpark, in addition to the paperback wrap PDFs, ebook JPEG, and audiobook cover. Hardcover dust jackets with flaps are not yet supported.

Yes. If you have a coupon code, enter it in the coupon field at the top of the Pricing page before clicking "Buy." Codes apply a 10% discount to any credit pack and are one-time use per customer. If your code is not accepted, it may have already been used or may not be valid for this site.

Yes. Select "Book info" (Step 0) from the wizard navigation at any point to edit the title, subtitle, author name, trim size, page count, or paper stock. Changing the trim size, page count, or paper will regenerate the print templates and clear any cached downloads — simply re-proof the cover after saving your changes.

Yes. When you upload a cover image whose shape does not match the print panel exactly, BookCovers.pro detects the mismatch and shows a crop-alignment control on the front-cover screen. Choose center (default), top, bottom, left, or right to set where the crop is anchored — useful for keeping a face or a key visual element in the frame. The setting is saved and applied each time your proof previews or renders.

Yes, if your book has a subtitle. On the spine step, a "Show subtitle on spine" toggle appears when a subtitle is saved. Turning it on changes the spine text from the title alone to "Title: Subtitle." You can switch it back at any time before downloading.

No. Free accounts can generate up to three AI covers per day with no credit required — you will see a full-quality watermarked preview each time. Once you have any credit balance (any pack size), AI generations and refinements become unlimited. A credit is only spent when you click to download the final print-ready bundle.

After you generate a front cover, BookCovers.pro automatically checks whether any text crosses into the trim or bleed area. If it does, the proof page shows a warning and offers an Auto-fix (Outpaint) button that shrinks the design slightly and fills the new edges — usually resolving the issue in 20–40 seconds. You can also go back to the front-cover step and regenerate, or acknowledge the warning and proceed if the flagged element is intentional decorative art.

Yes. Paperback bundles include a print-ready wrap PDF for Lulu, alongside KDP and IngramSpark, each with its own spine-width formula — as long as your book is 32 pages or more (Lulu's own minimum). Shorter books get KDP and IngramSpark files only. Hardcover case-laminate is currently available for KDP and IngramSpark only — Lulu hardcover is not yet supported.

Yes. After downloading your print-ready bundle, a Distribute Print Book option appears on the proof page. BookCovers.pro sends your cover, interior PDF, and metadata to SelfPublishing.pro, which distributes through Ingram — putting your paperback on Amazon, Barnes & Noble, and thousands of other retailers worldwide. Distribution is free for BookCovers.pro users; SelfPublishing.pro takes 15% of net royalties. You can still upload the same KDP PDF directly to Amazon KDP yourself for tighter Amazon control.

Yes. On the back cover step, scroll to the Author section and toggle it on. You can upload a photo with your choice of frame shape (circle, square, rounded rectangle, or portrait rectangle), write a short bio, and the section will appear on the final printed back cover. The author section is included in the same print bundle at no extra cost.

Yes. When you start a new cover project, your SelfPublishing.pro books appear in a dropdown on the setup form. Selecting one pre-fills the title, author name, trim size, page count, paper type, and back-cover description — so you skip re-entering details you have already set. You can adjust any field before continuing.

Yes. On the back cover step, switch the Background toggle from "AI background" to "Solid color." You can then pick any of the palette colors extracted from your front cover, or enter a custom hex color. The text color follows the Text treatment setting below the toggle, and "Auto" keeps it legible against any background.

Yes. The back cover description field accepts a small set of HTML formatting tags: use or for bold and or for italic. These render in the final print-ready PDF and in the on-screen proof preview. Other HTML tags are ignored. You can also use

for subheadings and

for bullet points.
