BookCoversLab

BookCoversLab is a KDP‑focused cover creator that turns Amazon’s complex print rules into a simple, guided workflow. Instead of guessing trim size, spine width, and bleed, you start with the exact KDP specs and design on the right canvas from the beginning.

The tool helps you create new covers or fix files that are already being rejected by KDP. You can diagnose common errors (size, wrap, resolution, spine, bleed), adjust the layout, and export a compliant, print‑ready PDF for paperback or hardcover without rebuilding everything from scratch.

BookCoversLab also includes AI cover generation so authors can quickly explore on‑trend, genre‑fit cover ideas before committing to a final design. You can import an existing ebook cover, automatically add the spine and back, and adapt the design when your page count changes — the spine updates without breaking the layout.

Beyond covers, BookCoversLab provides workflows for coloring books, mockups, and marketing creatives, plus KDP‑specific utilities like a cover size calculator, barcode generator, and sales calculator. It’s built for indie authors, small publishers, and designers who want fewer rejected files, faster approvals, and a clearer path from draft to KDP‑ready book.
