We built KDP Cover Tool because we were tired of getting covers rejected. After the fifth rejection for a wrong spine width, we decided to automate the whole process.
Self-publishing should be about your story, not about fighting with PDF specs and bleed settings. Professional book cover design was once only accessible to authors with big budgets and designer contacts.
KDP Cover Tool changes that. We give every indie author — whether you're publishing your first coloring book or your fiftieth thriller — the same professional tools that major publishers use, for free or at a fraction of the cost.
No more spine width spreadsheets. No more KDP rejection emails. No more expensive designers just to get the dimensions right.
