Why Vellum doesn't work for PC authors
Vellum has earned its reputation for a reason — clean typography, solid defaults, and an interface built specifically for book formatting. The problem for most authors isn't the software, it's the operating system: Vellum has never released a Windows version, and there's no indication that's changing.
If you wrote your book on a PC, Vellum simply isn't an option unless you buy a Mac or rent access to one.
The real gap — you already wrote your book in Word
Most of the tools positioned as "Vellum alternatives" — Atticus, Reedsy, Kindle Create — still ask you to do the same thing Vellum does: import your manuscript into their editor and rebuild your formatting inside a new tool. That's a reasonable tradeoff if you're formatting from scratch, but it's extra friction if your manuscript is already finished and clean in Word.
KDPFormatter skips that step. You upload the DOCX you already have, and it generates a KDP-compliant print-ready PDF — correct trim size, margins, gutter, and interior formatting — without you touching a new interface.
When you should still use Atticus or Reedsy instead
To be fair to the alternatives: if you want deep typographic customization (custom drop caps, ornamental scene breaks, complex front/back matter), or you're producing an EPUB with heavy formatting, Atticus or Vellum's design-first approach may still serve you better.
KDPFormatter is built for authors who want a clean, professional interior fast, from a manuscript that's already in good shape — not for authors who want to design every visual detail from scratch.
Frequently asked questions
Is there a Vellum version for Windows?
No. Vellum has only ever been available for Mac, and there's no official Windows version. PC authors typically use Atticus, Reedsy Studio, or a tool like KDPFormatter that works from an existing Word manuscript.
Can I run Vellum on Windows using a virtual machine or Mac emulator?
Some authors have tried running Vellum through a virtual Mac environment, but this isn't officially supported by Vellum, can violate its licensing terms, and is unreliable enough that most PC authors avoid it in favor of a native alternative.
What's the fastest way to get a Word manuscript KDP-ready without switching software?
Upload it directly to a tool built for that conversion — KDPFormatter takes a finished Word manuscript and outputs a KDP-ready print PDF without requiring you to rebuild the formatting in a separate editor.
Does KDPFormatter work for both print and ebook formatting?
KDPFormatter currently creates KDP-ready print PDFs from your Word manuscript. Our EPUB generator is coming soon.
