The book formatting software that runs on a Windows PC is Atticus, Kindle Create, Affinity, Adobe InDesign, Microsoft Word, Deckle, and two browser tools, Reedsy Studio and the Draft2Digital formatter. Which one fits depends on four things: your budget, whether you work offline, which stores you publish to, and whether you also want to write in the same app.
No standards body ranks formatting software, so this page sorts the tools by need, with each vendor's own Windows requirements as of October 2026. Vellum is Mac only, and Vellum for Windows: why there isn't one covers that question. For the same tools across every platform, see book formatting software in 2026.
Windows system requirements for book formatting software
Each row comes from the vendor's own page, retrieved 20 October 2026. Where a vendor publishes no figure, the cell says so rather than guessing.
| Tool | Windows version | Processor | Memory | Disk | Other |
|---|---|---|---|---|---|
| Kindle Create | Windows 10 or later | 1.2 GHz minimum, 2 GHz recommended | 4 GB minimum, 8 GB recommended | not stated | free download from KDP |
| Affinity by Canva | Windows 10 or 11, 64-bit | x64 with SSE2 | 4 GB minimum, 8 GB+ recommended | 2.5 GB | DirectX 10 GPU, 1280x768 display, online once to activate |
| Microsoft Word (Microsoft 365, home use) | Windows 11 | 1.6 GHz or faster, 2-core | 4 GB (2 GB on 32-bit) | 4 GB | 1280x768 display, DirectX 9 for hardware acceleration |
| Adobe InDesign | see Adobe's requirements page | Adobe's page refused retrieval, so no figures are repeated here | |||
| Atticus | no minimum published | installed from Chrome as a web app; older systems may not install it but "it will always work in your browser" | |||
| Deckle | Windows 10 or 11, 64-bit | x86_64 build | not stated | not stated | .msi installer, offline after activation |
| Reedsy Studio | any browser | no browser list published; no offline mode | |||
| Draft2Digital formatter | any browser | browser "on any operating system"; needs a connection |
Two of these rows surprise people. Microsoft's Microsoft 365 home-use requirements list Windows 11 only. And Atticus has no Windows installer of its own: Atticus's help says "You'll need to use Chrome to do this", then you open app.atticus.io and click Install App.
Free book formatting software for Windows
Four tools cost nothing to format a book on a PC, and each carries a stated limit.
Kindle Create is Amazon's free desktop formatter, for Windows 10 or later. It imports DOC, DOCX or PDF and exports "Kindle Package Format (KPF) and EPUB", with EPUB available for reflowable books only. One project makes the Kindle ebook and the KDP paperback, with page numbers, headers and footers, page spreads and automatic widow and orphan handling. Amazon's feature chart still lists that route as "Pre-release (beta)", as of October 2026. Amazon's Kindle Create help states the limits itself: "Tables, footnotes, lists, and inline images imported from your DOC(X) file cannot currently be edited in Kindle Create", and themes "cannot be edited by the user". It produces no print PDF, so its print output goes to KDP only. Kindle Create suits an author publishing only on Amazon. Authors who outgrow it have a page of their own: Kindle Create alternatives.
The Draft2Digital formatter runs in any Windows browser and is free "even without ebook distribution". Draft2Digital's FAQ says you can "create, convert, and download a pixel-perfect paperback PDF or ebook EPUB file without having to publish through D2D". Print is black and white, perfect-bound paperback, in six trim sizes from 5x8 to 8.5x11 inches, 32 to 1,050 pages. It needs an internet connection and has no writing tools.
Reedsy Studio is a free browser app for writing and formatting, with paid add-ons (Craft $4.99 a month, Outline $7.99 a month, as of October 2026). It exports EPUB 3 and two PDFs: a print-ready version that "removes links and uses CMYK images", and a screen version. Asked whether it works offline, Reedsy's FAQ answers "Currently, no."
Affinity by Canva is free professional page layout for Windows 10 and 11, with a free Canva account. It is described in the page layout section below, because it is design software rather than a manuscript formatter.
Book formatting software for Windows that works offline
Three Windows tools work fully offline once installed: Kindle Create (a desktop app), Affinity, and Deckle. Affinity needs a connection once: "You will need to be online to download and activate your license". After that, "there is no requirement to be online, even with extended offline periods." Word and InDesign are installed desktop apps, but their vendors' pages we read make no offline statement, so this page makes none for them.
Atticus advertises "Work online, offline, in a plane or on a train". Its help centre states the limit in its own words: "you can write while offline and it will sync to the server once you are back online. You do need to be online to import and export files, however." On Windows, that means you can draft offline in Atticus but not produce your EPUB or PDF without a connection.
Reedsy Studio and the Draft2Digital formatter need a connection for everything.
Software to write and format a book on Windows in one app
Three tools here take a book from first draft to finished files on a PC: Atticus, Reedsy Studio and Deckle.
Atticus costs $147 once, "No monthly fees. Forever.", with a 30-day money-back guarantee (as of October 2026). It exports EPUB, PDF and DOCX, and offers 17+ chapter themes, a custom theme builder, 1,500+ fonts, full-bleed images, large print and footnotes. It also has collaboration "for authors, editors, and readers", which Deckle does not have. Atticus lists version history as "Coming Soon" and lists no free trial. Its alternatives are compared in Atticus alternatives.
Reedsy Studio is the free option, with real-time co-authors and editors, and it works only online.
Deckle is our app, so weigh this section accordingly. Deckle is a desktop app for Windows, macOS and Linux. The Windows download is a 64-bit .msi for Windows 10 or 11. A Deckle project is a folder on your own disk: one .deckle database holds the writing, notes and settings, beside research/ and .deckle-assets/ folders. It works offline after activation, and one licence covers two devices in any mix of Windows, Mac and Linux.
For writing, Deckle has a Binder (Draft, Research, Trash), an Outliner with a Grid View of index cards and a List view, and Continuous View. It adds a Codex for characters, locations and items, a Timeline, inline comments, snapshots and Writing Stats. For formatting, it has 26 built-in style presets, 8 trim sizes, bleed, drop caps, small caps, running heads and scene break ornaments. Widow and orphan control is a setting, off by default, and special pages run from Title Page to Also by the Author.
Margins and gutter for the print PDF, set in Styles
It exports EPUB (Generic, Kindle, Apple Books and Kobo targets), a print PDF typeset with Typst, DOCX, Markdown and plain text. It has no generative AI.
EPUB, PDF and Word from the same book
Where Deckle is behind on Windows: it has no browser version, so unlike Atticus and Reedsy Studio it cannot run on a Chromebook or a borrowed PC without installing. It offers 8 trim sizes and no custom size. Its print PDF is a standard PDF, not PDF/X-1a. Four tools on this page are free, and Deckle is a paid one-time purchase.
Professional book layout software for Windows: Affinity and InDesign
Affinity and InDesign lay out any printed page by hand. They give the finest typographic control on this page and have no manuscript tools. Affinity's Books panel combines separate documents "as chapters", per Affinity's help on books, but each one is laid out by hand.
Affinity by Canva combines "professional design, photo editing, and page layout" in one free app, with page layout in its Layout studio. It exports PDF with bleed and crop marks, and EPUB. It has Smart Master Pages and shared text styles, and it opens InDesign IDML files and, since the September 2026 update, native INDD files. The old Affinity Publisher 2 still runs, but "these apps won't receive future updates". Affinity's AI tools are image and vector tools that need a paid Canva plan.
Adobe InDesign is the professional standard for page layout, sold by subscription at US$22.99 a month for the single app on an annual plan billed monthly (as of October 2026). It has a Preflight panel that flags missing fonts, low-resolution images and overset text, plus paragraph and character styles, parent pages and automatic chapter numbering. Its 7-day trial "will automatically convert to a paid" membership unless cancelled. It includes generative AI such as Layout-aware Rewrite. Adobe publishes InDesign's Windows requirements on its help site, which refused automated retrieval on 20 October 2026, so check them there before you subscribe.
Choose one of these for an illustrated book, a cookbook or poetry with exact line placement. For a text novel, each chapter becomes a manual layout job.
Can you format a book in Microsoft Word on Windows?
Many Windows authors already own Word, and KDP supports it directly. KDP's paperback and hardcover templates are Word files, offered as "blank templates" with page size and margins set and as "templates with sample content". KDP warns: "Make sure to remove any template sample text from your final manuscript." KDP accepts DOCX for ebooks and for print interiors without bleed.
Word has two limits for book work. It does not save EPUB. And Microsoft's file format reference notes that a saved PDF "might not have a perfect page-to-page correspondence with the original… pages might break at different locations", so check the PDF, not the document, before upload. Microsoft 365 Personal costs $9.99 a month or $99.99 a year, and Office Home 2024 costs $179.99 one-time for one PC or Mac (as of October 2026). KDP's own Word route is covered in KDP formatting software.

Which book formatting software should a Windows author choose?
- You publish only on Amazon and want to spend nothing: Kindle Create.
- You want a free paperback PDF and EPUB and are always online: the Draft2Digital formatter, or Reedsy Studio if you also want to write there.
- You want to design every page by hand: Affinity (free) or InDesign (subscription).
- You already own Word and publish a plain novel to KDP: Word with KDP's templates, plus a separate EPUB tool.
- You want to write and format in one app and need a browser or Chromebook option: Atticus.
- You want to write and format in one desktop app that works fully offline, with separate Kindle, Apple Books and Kobo EPUBs: Deckle.
Whatever makes the file, KDP's rules decide whether it prints. They are listed in KDP print file requirements, and the ebook side is in how to make an EPUB file.
Try Deckle on Windows
Deckle has a free demo. Install Deckle, then click Take Deckle for a Spin on the screen Deckle opens to. It needs no card and no account, and it has no time limit. It opens a sample novel with every screen open to explore, and you can restyle it and export real EPUB, PDF and DOCX files to compare with your current tool. New writing is capped at about 500 words, and new documents and imports are blocked. Deckle itself is a one-time purchase.
