What Authors Are Saying

★★★★★

"I spent two days trying to get my cover dimensions right in Canva. This tool did it in 5 minutes. The spine width was exact — KDP accepted it first try."

"Way cheaper than hiring a designer for my low-content books. I can knock out a cover in 10 minutes now and the 300 DPI exports look sharp in print."

"The back cover and spine layout is what sold me. Every other tool only does the front. This gives you the full wraparound PDF that KDP actually needs."

Frequently Asked Questions

❓ Do I need design experience?
No! KDP CoverLab is built for non-designers. Upload your images, add text, and export — we handle all the technical KDP requirements automatically.
❓ Will my covers pass Amazon KDP's checks?
Yes. We use Amazon's exact spine formulas for both paperback and hardcover (case laminate) and include proper bleed/trim zones. Our exports are 300 DPI and match KDP's specifications perfectly.
