BookCoversLab
BookCoversLab is a browser-based KDP cover creator built specifically for Amazon KDP authors. It automatically handles trim sizes, bleed, and spine math so you don’t need spreadsheets or manual calculations.
With the built-in KDP cover calculator, BookCoversLab supports all common KDP trim sizes and paper types, and dynamically updates the spine width when you change your page count. Real-time preflight checks validate 300 DPI resolution, CMYK color profile, bleed, and safe zones, helping your cover pass KDP review on the first try.
Authors can start from professional templates based on 10,000+ bestseller covers, or generate unique backgrounds using AI cover generation. You can convert an existing Kindle ebook cover into a full paperback or hardcover wrap in minutes, then export a print-ready PDF/X-1a:2001 file ready for upload to Amazon KDP.
BookCoversLab is ideal for indie authors, small publishers, designers, and KDP beginners.
