Everything a KDP cover needs
Sized by KDP’s rules
Back, spine and front with 0.125″ bleed for all 16 KDP paperback trims. The spine follows your page count and paper.
Guides you can trust
Trim lines, spine folds, safe zones and the barcode area are drawn on the cover while you design, and left out of the file.
Text, images and shapes
Titles in any font, your own images or free stock photos, shapes, lines, decorations and QR codes, with layers and undo.
KDP-ready files
One PDF of the full cover at 300 DPI, the way KDP asks for it, the front as a 2560 px Kindle eBook cover (JPG), or a PNG for ads.
Free forever, no watermark
No credits, no watermark, on every plan. You may sell the cover; only a free account is needed to download.
Grows into a whole book
Need the inside too? Pick a puzzle book on the Create page: it takes this cover along, and the spine follows the book’s page count.

KDP cover creator FAQ
Is the KDP cover creator really free?
Yes, forever and on every plan. Covers download without credits and without a watermark, and you may sell them. You only need a free account (no credit card) to download.
Can I use it for a book I did not make here?
Yes. Type in your trim size, page count and paper, and the cover is sized for that book — novels, journals, notebooks or puzzle books made anywhere.
What file do I upload to KDP?
The cover PDF: one page with the back cover, spine and front cover plus 0.125″ bleed, at 300 DPI. KDP takes the interior and the cover as separate files.
What if my page count changes?
Type the new page count above the cover: the spine and the full cover size update, and the design moves with them — the front stays on the front, spine text stays centered. KDP prints spine text only from 80 pages on.
Where does the barcode go?
KDP adds it in the lower right of the back cover. The cover creator marks that 2 × 1.2″ area, so you can keep it free of text and images.
Does it make hardcover or Kindle covers?
Kindle yes: Download cover also saves the front as a 2560 px tall JPG for your eBook. Hardcover wraps not yet; the free KDP cover size calculator gives their size and a template.
