Book formatting
Convert Word to EPUB — Properly
Not a file-format shove: chapter detection, a real navigation TOC, preserved italics, and valid EPUB3 structure from your .docx.
Most Word-to-EPUB converters transliterate the file: you get one giant chapter, broken italics, and a table of contents that lists nothing. Ceeryo converts the way an ebook formatter would: it detects your chapters and scene breaks, preserves italic and bold runs, builds a real EPUB3 navigation document, and produces title and copyright pages — so the file opens correctly in Kindle Previewer, Apple Books, and Kobo. Because it's the same engine that typesets print interiors, you can download the paperback PDF from the same upload.

You'll confirm chapters, title and front matter before anything is set. Your words never change — only the typography.

How it works
From manuscript to book in four steps
The fastest way from a finished Word manuscript to print-ready files — no templates, no desktop app, no per-page fiddling.
- Step 1
Upload your manuscript
Drop in the .docx manuscript you have finished writing. Your file is processed only to typeset it and is never used to train models.
- Step 2
Chapters are detected
Chapter openings, scene breaks and italics are found automatically, without changing a word of your text.
- Step 3
The book is typeset
Trim size, margins and gutter, running heads, drop caps and chapter openers are set as a real book interior.
- Step 4
Download print PDF + EPUB
A print-ready interior PDF at your chosen trim size plus a clean EPUB, checked against the geometry KDP enforces.
In short
A good Word-to-EPUB conversion needs chapter splitting, a real navigation TOC, preserved italics, and valid EPUB3 structure — not just a format change. Ceeryo detects your manuscript's structure and builds a clean EPUB3 (plus a print PDF) from one .docx upload.
Why does my EPUB show one giant chapter?
Because the converter didn't detect chapter boundaries — it wrapped the whole document in a single section. Ceeryo splits on your chapter headings ('Chapter One' lines or Heading 1 styles), gives each chapter its own file inside the EPUB, and builds the navigation TOC from them, which is what e-readers use for chapter jumps.
Structure first
The TOC is the tell
Open any badly converted ebook and check the table of contents — empty or one entry. E-readers build navigation from the EPUB nav document, not from what the text looks like. Ceeryo writes that nav from your actual detected chapters, which is why the chapter list works on every reader.
Features
Why authors choose Ceeryo
Real chapter files
Each detected chapter becomes its own XHTML file with the label and title preserved.
Navigation TOC
A proper EPUB3 nav document so readers can jump chapters on Kindle, Apple Books, and Kobo.
Validated structure
Every generated file is checked for well-formedness before packaging.
Use cases
Where Ceeryo works best
Kindle edition
Upload the EPUB straight to KDP for the ebook edition.
Wide distribution
The same EPUB works for Apple Books, Kobo, and Draft2Digital.
ARC copies
Send early readers a clean ebook instead of a Word file.
Why not do it by hand?
Ceeryo vs. doing it manually
Typesetting a book by hand in Word or InDesign takes days and rarely passes KDP's checks the first time. Here's the difference.
Output quality
What the finished book files look like
Every run produces a preflight-checked print PDF and a clean EPUB — never a rewrite of your words. Here's what you get.
- Valid EPUB3 with nav document and correct spine order
- Italics, bold, and small caps preserved as real markup
- Scene breaks rendered as typographic separators
- Title and copyright pages generated from your metadata

Frequently asked questions
Does it work with Kindle?+
Yes — KDP accepts EPUB uploads for ebooks and converts them to Kindle format. The clean structure is exactly what makes that conversion behave.
Are fonts embedded in the EPUB?+
No — e-readers override fonts with the reader's settings, so embedding mostly adds file size. The EPUB uses clean serif styling that respects reader preferences.
What about my italics?+
Preserved as real emphasis markup, run by run — the most common thing other converters break.
