BookCoversLab

BookCoversLab is a book formatting tool. A KDP-focused cover studio for indie authors: lock trim, spine and bleed first, then build or repair a paperback, hardcover or ebook wrap and export a print-ready PDF. Also handles AI coloring book interiors and 3D mockups.

BookCoversLab is a cover production tool built specifically around Amazon KDP submission rules rather than general graphic design. Instead of starting with a blank canvas and hand-typing bleed and spine values, authors enter the trim size, page count and paper type first, and the workspace is generated from those numbers. That reversed order is the product's core idea: specs first, artwork second, so a file is never designed on a canvas that KDP will later reject. The workflow covers three situations authors actually land in. A new cover can be built inside the KDP Cover Creator for paperback or hardcover, with trim, spine, bleed, barcode area and safe zones checked before export. An ebook cover can be imported and turned into a full print wrap, with the spine and back cover added around the existing front artwork. A rejected or broken file can be diagnosed through the cover error checker, which looks at size, wrap, resolution and other common causes, then repaired in the same environment and re-exported as a print-ready PDF. The same logic extends to coloring books, which follow identical KDP rules for trim, bleed, 300 DPI and cover wraps that must match the interior page count. The AI Coloring Book Generator produces line-art pages, adds blank backs and page numbers, and exports an interior PDF. Smaller utilities sit alongside it: a photo to coloring page converter, a name-based bubble letter generator, a coloring page generator with preset sizes, a coloring book cover maker, a size calculator and a free 3D mockup tool for listings and ads. The audience is indie authors and small presses who publish often and want fewer upload cycles, not designers looking for a full illustration suite. Compared with generic editors, the trade-off is deliberate: narrow KDP focus and preflight checks in exchange for fewer freeform design options. AI cover generation is bundled at each pricing tier in limited counts, so it supports concept work rather than replacing licensed artwork.
