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.

How it works

How to vellum for windows in four steps

The fastest way to vellum for windows without manual copy-paste, screenshots, or formatting cleanup.

  1. 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.

  2. Step 2

    Chapters are detected

    Chapter openings, scene breaks and italics are found automatically, without changing a word of your text.

  3. 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.

  4. 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

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.
