As answered by people managing JavaScripting and KDP Print Cover.
KDP Print Cover's answer:
KDP Print Cover Generator is the only free tool that takes your existing Kindle eBook cover and automatically builds a complete, print-ready full-wrap PDF — back cover, spine, and front cover — sized to Amazon KDP's exact specifications. You don't need design software or manual calculations. Enter your book specs, upload your cover, and download a submission-ready PDF in seconds.
KDP Print Cover's answer:
Most alternatives require you to design from scratch in a drag-and-drop editor, or pay for credits/subscriptions. KDP Print Cover Generator skips all of that — if you already have an eBook cover, you can generate a print cover in under a minute, completely free. It uses KDP's official formulas for spine width and PDF dimensions, supports all 16 paperback trim sizes plus 5 hardcover sizes, and outputs a 300 DPI, print-ready PDF that passes KDP's file checker without guesswork.
KDP Print Cover's answer:
Self-published authors who are publishing a paperback or hardcover on Amazon KDP and already have a Kindle eBook cover. Typically indie authors, first-time publishers, and authors transitioning from digital-only to print distribution who want a fast, accurate, no-cost way to create their print cover without hiring a designer or learning new software.
KDP Print Cover's answer:
The tool was built out of frustration with the existing workflow. Authors who already have a professional eBook cover shouldn't need to start from scratch or pay again just to get a print version. KDP's own Cover Calculator gives you dimensions but doesn't generate the file. Third-party tools either charge credits or require full redesign. KDP Print Cover Generator was built to close that gap — take what you already have, and produce a spec-compliant print cover automatically.
KDP Print Cover's answer:
React (frontend), Node.js + Express (backend API), PDFKit for pixel-perfect PDF generation at 300 DPI, and Sharp for server-side image processing. Deployed on Vercel (frontend) and Railway (backend).
KDP Print Cover's answer:
KDP Print Cover Generator is used by individual self-published authors on Amazon KDP. As a free tool, our users are primarily indie authors rather than enterprise customers.
