Need More Than Calibre for Your Book?
Calibre is a great ebook library and converter, but for publishing it produces EPUBs that are valid yet visually rough, and it doesn't give you a print-ready KDP paperback PDF. If you want a professionally typeset 6x9 print interior and an accessibility-ready EPUB from your manuscript, upload your .docx and preview the pages here.

Frequently asked questions
What's the limitation of Calibre for publishing?
Calibre excels at format conversion and library management, but its output EPUBs are engineered for reading apps, not styled for sale, and it produces no KDP print-ready PDF. Fine-tuning its output requires editing HTML/CSS by hand.
What does PaperbackKit produce instead?
A print-ready 6x9 KDP interior PDF with real chapter openers and mirrored margins, plus an EPUB built with EPUB Accessibility 1.1 / WCAG techniques for the EU Accessibility Act — from one Word upload, previewed before paying.
Is my EPUB valid?
Yes; the EPUB is generated with proper structure, navigation and accessibility metadata. The difference from a raw Calibre conversion is professional typesetting and print output, not just validity.
Do I need to know HTML/CSS?
No. PaperbackKit is automatic — upload the .docx, review the typeset pages, and download the print PDF and EPUB.
