No manuscript handy? — it runs through exactly the same pipeline as your own file.

What reflowable means

One file, and the reader decides how it looks

A Kindle book has no pages. The reader picks the typeface, the size and the margins, and the text rewraps around whatever they chose — which is why anything pinned in place fights the device instead of working with it.

Chapter One

The bell in the north tower had not rung for eleven years, and Marta had grown used to the silence the way one grows used to a scar: not fondly, but without argument.

Navigation

Your chapters should behave like chapters

The Go To menu is built from the ebook's own navigation document. A contents page you typed by hand does nothing — and page numbers are meaningless in a reflowable book anyway, because there are no fixed pages to number.

A fair question

Why not just upload Word to KDP?

You can — KDP accepts both. The difference is not whether it works but who decides the structure, and when you find out what it decided.

Word uploaded directly

A prepared EPUB

Conversion happens after you upload

Structure is prepared first

Navigation depends on how Word was used

Chapters explicitly structured

Errors surface after upload

Preview before publishing

Tabs and manual page breaks may not survive

Ebook-safe structure throughout

Control the structure before you publish it.

What you get

Two files, because Amazon takes two routes

Primary
EPUB
each chapter its own section, so Go To and the progress bar work
Also
DOCX
real heading styles, for Kindle Create or a Word upload
Pinned
Nothing
no forced fonts, sizes or page numbers — the reader's settings win
Scene breaks
Marked
a centred marker, not a blank line that vanishes at a screen edge
Metadata
Embedded
title and author, so the library shows it correctly
Your prose
Untouched
layout and punctuation style only

What KDP requires

Fewer things than people expect, and easy to get wrong by hand

  • An accepted file type. EPUB or Word. Kindle Direct Publishing takes both, and converts whichever you give it — so handing it an EPUB means you decided the structure rather than Amazon guessing at it.
  • Real navigation, not a typed contents page. The Go To menu is built from the ebook's own navigation document. A contents page you typed by hand, with page numbers, does nothing.
  • Reflowable text. The reader chooses the typeface, size and margins. Anything you pin — fixed font sizes, forced page breaks mid-chapter — fights that and looks broken on a device you did not test.
  • The cover uploaded separately. KDP takes the cover as its own image; it is not part of the interior file.

Need the paperback too?

Submitting to agents first?

The same manuscript feeds all of them. Doing several editions is normal — see the print formatter for why an ebook and an interior are not two versions of one file.

Questions

Kindle and KDP, answered

Is KDP formatting the same as Kindle formatting?

For an ebook, yes. Kindle Direct Publishing is the service you publish through, and Kindle is what people read on — so “format my book for KDP” and “format my book for Kindle” describe the same file. The one place the words diverge is print: a KDP paperback or hardcover needs a completely different file, and that is a different tool.

What does Amazon KDP actually accept?

KDP takes EPUB, and also Word .docx. EPUB is the safer choice: it is what Kindle uses internally, so what you upload is much closer to what readers see. We give you both.

What is a reflowable ebook?

One where the reader chooses the font, the size, and the margins, and the text re-wraps to fit. That is how nearly all Kindle novels work. It is the opposite of a print PDF, where the page is fixed — which is why we do not produce a PDF here.

Will my chapters show up in the Kindle menu?

Yes. Each chapter becomes its own section with a navigation entry, so the Go To menu and progress tracking work properly. Chapters you wrote as plain bold paragraphs are detected too.

Do I need separate files for the ebook and the paperback?

Yes, and this catches people out. An ebook is reflowable — no fixed pages, because the reader picks the type size. A paperback is a print-ready PDF at an exact trim size with mirrored margins. They are not versions of one file; they are two different objects built from the same manuscript. Format the ebook here and the interior with the print book formatter.

Do I need a cover?

KDP asks for a cover image separately when you publish, so you do not need one here. This tool handles the interior — the text, structure, and navigation.

Can I use this if I have never published on KDP before?

That is who it is for. You do not need to understand EPUB, navigation documents or Kindle Previewer — upload the Word file you wrote the book in and you get back something KDP will accept. If a chapter heading is ambiguous we ask rather than guess.

Does this change my writing?

No. Layout and punctuation style only — curly quotes, em dashes, consistent spacing. Your sentences are never rewritten or edited.

What does it cost?

Formatting is free. Free files include a short closing line crediting the tool, allow three adjustments, and are kept for 24 hours. Unlocking one file costs $5 once — no subscription — which removes that line, lifts the adjustment limit, and keeps the file for 7 days.

Checked against the source

The requirements on this page are published by the organisations below, not by us. We last read them in September 2026 and compared them against what the tool produces. If a requirement has changed since, the source is right and we are wrong — tell us and we will fix it.
