Vellum for Windows
Vellum doesn't run on Windows — and the usual answer is buying different desktop software. The browser needs no port.
Every list of Vellum alternatives for PC ends the same way: buy Atticus for $147, or learn a design tool. Both answers assume the solution is another installed app. Ceeryo takes the other path: upload the Word manuscript you already wrote, pick a designed interior theme and trim size, and download a print-ready KDP interior PDF and EPUB from the browser — Windows, Mac, Linux or a Chromebook, identically. Chapters and scene breaks are detected from your document, the gutter is set from your book's real page count against KDP's brackets, and the preflight shows every check passing before you pay for anything. No app, no license, no learning curve: your words are never changed, only typeset.

You'll confirm chapters, title and front matter before anything is set. Your words never change — only the typography.
Real output
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
Vellum is Mac-only. On Windows, Ceeryo formats your book in the browser: upload the .docx, choose a theme and trim, and download a print-ready KDP interior PDF plus EPUB, with KDP's margin and gutter rules checked against your actual page count. Pay per book instead of $147–$249 for an app.
Can I use Vellum on Windows?
No — Vellum runs only on macOS, and there is no Windows version. Windows authors either buy different desktop software like Atticus ($147), or use a browser-based formatter. Ceeryo runs entirely in the browser: upload your Word manuscript, pick a theme and trim size, and download the print-ready PDF and EPUB, priced per book rather than per license.
No port needed
The answer to a Mac-only app isn't another app
Workarounds for Vellum-on-PC — cloud Macs, VMs, buying a used MacBook — all solve the wrong problem. The typesetting runs on our servers; your machine only needs a browser. That also means nothing to update, and the same workflow when you switch computers.
- Works on Windows, Mac, Linux, Chromebook — identically
- Takes the .docx you already have; nothing to import or relearn
- KDP preflight: trim, page count, gutter and fonts checked before you pay
- Per-book pricing — not a $147–$249 license for one book a year

Use cases
Where Ceeryo works best
Windows authors
The whole Vellum experience without the Mac requirement.
One book, not a toolchain
Publishing one memoir or novel doesn't justify a $147 license.
Switchers mid-series
Same manuscript in, consistent interiors out — whatever machine you're on.
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.
- Print-ready interior PDF at your chosen trim size
- Gutter set from your book's real page count per KDP's brackets
- Clean EPUB for the ebook edition from the same upload
- Your words untouched — typography only

Other ways to turn your Word manuscript into a finished book.
A Vellum alternative that runs in the browser
Vellum is excellent — and $249, Mac-only, and another app to learn. The alternative: upload the manuscript, download the book.
formatterAn Atticus alternative for finished manuscripts
Atticus wants to be where you write. If your book is already written in Word, you need a typesetter — not a second home for your text.
formatterConvert Word to EPUB — Properly
Not a file-format shove: chapter detection, a real navigation TOC, preserved italics, and valid EPUB3 structure from your .docx.
formatterFormat Your Romance Novel
The Colette theme: elegant chapter numerals between hairlines, a warm readable serif, and ornamented scene breaks — made for romance.
formatterKDP margin checker
Every margin calculator repeats Amazon's table. The question that gets books rejected is whether your PDF actually meets it.
formatterWord count to book pages — measured, not estimated
Most words-per-page tables are guesses. These numbers come from actually typesetting manuscripts at each trim size.

Frequently asked questions
Is there any way to run actual Vellum on Windows?+
Only indirectly — renting a cloud Mac or running macOS in a VM, both of which cost money, violate no one's expectations of fun, and still leave you maintaining a workaround. Most Windows authors choose different software instead.
How does this differ from Atticus on Windows?+
Atticus is a $147 writing-and-formatting app you install and work inside. Ceeryo is a browser tool that takes the finished Word manuscript you already have and returns the typeset files, priced per book. Less control, far less to learn — see the full comparison.
Do I get both print and ebook files?+
Yes — the print interior PDF at your chosen trim size and an EPUB, generated from the same upload.
