✓ Full Wrap Cover — KDP Submission File
KDP requires ONE single file: back cover + spine + front cover combined. This assembles both panels you uploaded above into that single file.
Live preview
Upload both back and front cover images above to enable the full wrap export.
Tip: The panel downloads above are for previewing each side individually. For your actual KDP print submission, always use the Full Wrap Cover file — KDP's upload form only accepts one combined back+spine+front PDF, not separate files.
Export
Download KDP-ready files. All pages are resized to your trim with your chosen fit modes.

Fixed layout EPUB preserves your exact print design — ideal for workbooks, journals, illustrated books, and children's books.
Reflowable EPUB wraps each page image in a scrollable chapter — better for standard Kindle readers and accessibility.
