FAQ
What can I do with BookCoversLab?
You can create a new cover in our Cover Creator, verify specs with the Size Calculator, rebuild an ebook cover into a paperback wrap, and start a coloring book workflow when interiors need more work.
Can BookCoversLab fix rejected KDP files?
Yes. If your file is failing KDP checks, BookCoversLab helps you diagnose the likely issue, fix the file, and export a cleaner version without starting over.
Which workflow should I start with first?
Start with the Cover Creator if your cover is the part blocking publication. If you are working on a coloring book interior, begin with the coloring book workflow.
Do I need to start over if my cover size is wrong?
No. Use the Size Calculator or the Cover Creator to lock the right trim, spine, and bleed, then fix the current file instead of rebuilding everything from zero.
Can you turn an ebook cover into a paperback wrap?
Yes. Use the ebook cover to paperback workflow to add the spine and back cover around your existing front cover.
Can you fix coloring book formatting issues before I upload to KDP?
Yes. The coloring book workflow helps you plan, review, and improve formatting-related issues before export.
