Book formatting software for Windows
If you have asked an author group what to use, you have been told Vellum. Vellum is macOS-only, so that advice is not usable, and working out what is has become unusually hard as a result.
Here is what genuinely runs on Windows, what each one costs, and how to pick between them.
First, the Vellum question
Vellum does not run on Windows and its publisher has not released a Windows version. That is not a temporary state of affairs — it has been true for the whole life of the product.
The workarounds authors use, and what they actually cost:
- Rent a cloud Mac
- Services rent a hosted Mac by the hour. It works, and you pay again every time you need to fix a typo. Practical for a one-off; expensive as a workflow.
- Borrow a Mac
- Fine for the initial format. Painful when the book needs a change six months later and the Mac belongs to someone else.
- Pay a formatter
- Typically £100–£300 a book. Sensible if you publish rarely; a recurring invoice if you revise.
- Run macOS in a VM
- Outside Apple's licence terms on non-Apple hardware. Not something we would recommend or help with.
All four are ways of paying to work around a limitation. The alternative is a tool that runs on the machine you own.
What runs on Windows
Installed Windows applications
- Alhora — ours. A native 64-bit Windows build; the book and its files live on your own disk.
- Adobe InDesign — what the trade uses. A subscription, a steep learning curve, and no knowledge of what KDP requires.
- Microsoft Word — you already have it. Workable for one short book; painful for print and for anything you revise.
- Calibre — free, and a format converter rather than a typesetting tool. Excellent at what it does; it does not design a book.
Browser-based, which works on Windows by definition
- Atticus — a one-off purchase, writing tools plus formatting, with an offline mode.
- Reedsy Book Editor — free, collaborative, fewer design options.
The real choice is between an installed application that keeps your book on your machine, and a browser application that keeps it on someone else's. Both are legitimate; the answer depends on how you feel about a manuscript living in someone else's account.
Things that are specific to Windows
- Fonts
- Windows ships with fonts that are frequently NOT licensed for embedding in a PDF or EPUB. Calibri and Cambria are convenient and are the usual trap. Check the licence, or use an open-licence book face.
- Word's PDF export
- Fine for a simple interior IF you set the page size to your trim and use mirrored margins. It does not do proper widow and orphan control, and its hyphenation is not built for book measures.
- Path lengths
- Windows has a long-standing 260-character path limit that some tools still hit. Keep projects out of deeply nested folders under Documents.
- File extensions
- Hidden by default. Turn them on before you start uploading files to retailers — it removes a whole class of confusion about what you are actually submitting.

Questions, answered
What is the best book formatting software for Windows?
Ours, and here is the reasoning rather than the assertion. The deciding question on Windows is not features but shape: Atticus is a browser tool that also lets you write, with the book in an account; Reedsy Book Editor is the free browser option, with a small set of templates and no print production. Alhora is an installed application, the book stays a file on your disk, and the print side is finished rather than started — per-printer spine widths, gutter by page count, pre-flight before upload. You can format and preview a whole book free and check that claim against your own manuscript.
Is there a Vellum for Windows?
No. Vellum is macOS-only and no Windows version exists. The closest equivalents that run natively on Windows are Alhora and Atticus.
Can I format a book in Microsoft Word?
Yes, and people do. Set the page size to your trim, use mirrored margins, and export a PDF. What you give up: reliable page breaks when a font substitutes, book-grade hyphenation and justification, real widow and orphan control, and any notion of a gutter that widens with page count.
Do I need Windows 11?
No. Alhora needs Windows 10 or later. Most browser-based tools need only a current browser.
Will a book formatted on Windows look different from one formatted on a Mac?
It should not, and with Alhora it does not — the same project produces the same PDF and the same EPUB on either. Where differences creep in is fonts: a book set in a face installed on one machine and not the other will substitute and repaginate.
A native Windows build, not a workaround
Alhora is a real Windows application — a 64-bit installer, not a browser tab and not a rented Mac. Format and preview a whole book free.
