Turn Your Manuscript into a Print-Ready PDF
From double-spaced draft to typeset book interior — trim size, margins, chapter design, and preflight in one pass.
A manuscript and a book interior are different documents. The manuscript is double-spaced Times New Roman on Letter paper; the book is a 6×9 (or 5×8) page in a real book face with justified text, drop caps, running heads, folios, and chapters that open recto. Ceeryo performs that transformation directly: upload the manuscript .docx, choose a theme and trim, and the engine typesets the entire book and verifies the print geometry before you download. No InDesign, no templates, no per-page fiddling.

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

What the typeset pages actually look like
Chapter opener and body page from each interior theme — rendered from the engine's real output at 6×9, not mockups.
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 print-ready book PDF has exact trim-size pages, mirrored margins with a page-count-based gutter, embedded fonts, and trade-book conventions like recto chapter openers and running heads. Ceeryo produces it from your Word manuscript in one upload — with a preflight report instead of guesswork.
What makes a PDF 'print-ready' for a book?
Four things printers and POD platforms check: the PDF page size equals the book's trim exactly; inside/outside margins mirror across the spread with a gutter sized to page count; all fonts are embedded in the file; and the page count sits within the printer's binding range. Ceeryo's preflight verifies each one and shows you the result.
Draft → book
The transformation, not a template
Templates ask you to pour text in and fix a hundred details. Ceeryo reads the structure you already wrote — chapters, scene breaks, italics — and re-typesets it under a designed system, so the 'template work' simply doesn't exist.

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.
- Exact-trim pages, verified across the whole document
- Book faces embedded and subset (Garamond, Crimson, Source Serif lineages)
- Widow and orphan control with hyphenated justification
- Recto chapter openers with suppressed running heads

Frequently asked questions
My manuscript is double-spaced — is that a problem?+
No. Manuscript spacing is ignored; the theme's leading is used instead. Your draft can look however it looks.
Can I print anywhere, or only Amazon?+
The output is a standard exact-trim, fonts-embedded PDF — the same thing IngramSpark, Lulu, and local printers ask for. KDP's page-count bracket is the strictest check applied.
What if my chapters aren't detected?+
The result screen shows the detected chapter list. If something's off, mark chapters with 'Chapter One'-style lines or Heading 1 styles and re-upload — those two conventions cover the parser.
