Tools for Formatting Your Books
The formatting tools below address different aspects of book production—from automated EPUB conversion to code-level ebook editing to professional print layout. Each tool has different strengths, and your choice depends on whether you need quick automated formatting, precise control over design, or something in between.
Reedsy Studio
Reedsy Studio emerged from the Reedsy marketplace's mission to democratize professional publishing tools, offering free browser-based formatting that follows traditional publishing standards automatically. Serving hundreds of thousands of indie authors, it handles all technical details—margins, spacing, widows, orphans—invisibly while writers focus on their manuscript. What distinguishes Reedsy Studio is its commitment to export files that major retailers and print-on-demand services accept without rejection, eliminating trial-and-error frustration. By combining professional-grade output with zero learning curve, Reedsy Studio positions itself as the formatting solution for authors who want traditionally published results without hiring a professional formatter.
Key features:
- Web-based (no download required)
- Automatic typesetting with professional standards
- Three book templates with customization options
- EPUB3 export for ebooks
- Print-ready PDF for paperbacks
- Chapter and front/back matter management
- Preview across multiple device types
- Import from Word, Google Docs, or paste text
- Collaborative editing features
- Completely free with no limits
Best for: Authors who want professional formatting with zero learning curve and no cost
Draft2Digital
Draft2Digital built its free formatting tool to simplify wide distribution, recognizing that formatting shouldn't be a barrier to getting books into readers' hands across multiple platforms. Upload a Word document, choose a genre template, and within minutes you have professionally formatted EPUB, MOBI, and print-ready PDF files. Unlike tools requiring interface mastery, Draft2Digital respects how authors already work: write in Word with basic formatting, then let the tool handle technical transformation. While primarily known as a distribution aggregator, the formatting tool stands alone as genuinely useful and doesn't require distribution through them to access it.
Key features:
- Free Word to EPUB/MOBI/PDF converter
- Upload .docx files with basic formatting
- Genre-specific templates
- Automated chapter detection
- Automatic table of contents generation
- Multiple export formats (EPUB, MOBI, PDF)
- Preview before downloading
- Standalone tool (distribution optional)
Best for: Authors who write in Word and want automated formatting across multiple formats
Kindle Create
Kindle Create represents Amazon's attempt to lower the technical barrier for KDP publishing, offering a free desktop application that turns Word manuscripts into Kindle-ready ebooks with a few clicks. Taking a template-based approach with four pre-designed themes, it handles typography and layout automatically while its built-in previewer shows exactly how books will look on Kindle devices before publishing. However, Kindle Create's greatest strength—tight KDP integration—is also its limitation: files work beautifully on Amazon but aren't designed for wide distribution, and editing capabilities are deliberately limited. For authors publishing exclusively through KDP, Kindle Create delivers the fastest path from Word document to published Kindle book.
Key features:
- Free desktop application for Windows and Mac
- Imports .doc and .docx files
- Four pre-designed formatting themes
- Built-in Kindle previewer
- Supports images, drop caps, tables
- Exports to KPF (Kindle Package Format) and EPUB
- Direct upload to KDP
- Automatic table of contents
- Print replica support for fixed-layout books
Best for: Authors publishing exclusively on Amazon KDP who want the simplest path to Kindle formatting
Limitations: Limited to Amazon ecosystem; minimal customization beyond templates; not ideal for wide distribution
Calibre
Calibre was born in 2006 when developer Kovid Goyal built free, open-source software to manage and convert ebooks across different formats and devices. What started as a personal solution evolved into the Swiss Army knife of ebook management, now supporting conversion between more than twenty formats while serving as library organizer, metadata editor, and ebook viewer. Calibre embraces power and flexibility over simplicity, giving complete control over conversion at the cost of a steep learning curve and dated interface. This isn't a formatting tool for creating books from scratch—it's a conversion and management powerhouse for transforming existing ebooks between formats.
Key features:
- Free and open-source
- Converts between 20+ ebook formats
- Ebook library management
- Metadata editing and organization
- Integrated ebook viewer
- Send books directly to e-readers
- Batch conversion capabilities
- Extensive customization options
- Regular updates and active community
- Cross-platform (Windows, Mac, Linux)
Best for: Converting between formats and managing large ebook libraries
Limitations: Steep learning curve; dated interface; better for conversion than creating books from scratch
Sigil
Sigil was created in 2009 specifically to edit EPUB files with precision and control, establishing itself as the free, open-source standard for authors who need direct access to their ebook's underlying code. Unlike automated formatters, Sigil operates on the principle that you should see and control exactly what's happening inside your EPUB file—the HTML, CSS, and XML. It offers multiple views: WYSIWYG book view for visual editing, code view for direct HTML manipulation, and preview for real-time changes. Maintained by volunteer developers and supported by an active community, Sigil has evolved to handle EPUB 3's advanced features while remaining completely free. This is the tool for authors who want to understand and control their ebook formatting at the code level.
Key features:
- Free and open-source EPUB editor
- WYSIWYG book view and code view
- Split view for simultaneous visual and code editing
- Metadata editor
- Table of contents generator

- Find and replace with regex support
- Supports EPUB 2 and EPUB 3
- Plugin architecture for extended functionality
- Cross-platform (Windows, Mac, Linux)
Best for: Authors comfortable with HTML/CSS who want complete control over EPUB formatting
Limitations: Requires some technical knowledge; learning curve for those unfamiliar with code; focused solely on EPUB format
Atticus
Atticus was created in 2021 by Kindlepreneur founder Dave Chesson to solve the fragmented workflow of writing in one program, editing in another, and formatting in expensive, Mac-only software many couldn't access. Built as "what if Scrivener, Google Docs, and Vellum had a baby," Atticus delivers the all-in-one solution that works on every platform while delivering Vellum-quality formatting at a fraction of the price with no monthly subscription. Its core innovation is seamless integration: write, format, and preview in one place with automatic cloud backup, then export professional ebooks and print-ready PDFs without switching applications. Since launch, Atticus has rapidly gained adoption among indie authors building sustainable, multi-book publishing businesses who appreciate formatting unlimited books for one price.

Vellum
Vellum established itself as the gold standard of book formatting when it launched as a Mac-exclusive application, built to deliver beautiful, professional ebooks without requiring expensive designers or code mastery. For years it stood alone in delivering genuinely elegant formatting so valued that PC users would buy Mac computers or rent virtual Macs just to access it. The software's secret is its curated collection of professionally designed book styles and meticulous attention to typography details like widow and orphan control that automated tools typically ignore. Vellum's philosophy centers on making high-end book design accessible: choose a style, customize if desired, and Vellum handles thousands of micro-decisions that separate amateur formatting from traditional publisher quality. While competitors like Atticus have challenged its dominance with cross-platform access and lower prices, Vellum remains the choice for authors wanting the most beautiful possible books.
Key features:

- Import from Word, Scrivener, Ulysses
- Drag-and-drop formatting
- Preview across multiple devices
- Export to EPUB, MOBI, and print PDF
- Widow and orphan control
- Typography fine-tuning
- Chapter ornaments and design elements
- Format unlimited books (after purchase)
- Highly polished, intuitive interface
- Updates and new styles added regularly
Best for: Mac users who want the most beautiful possible book formatting
Limitations: Mac-only; premium pricing; no Windows or web version
Choosing Your Formatting Tools
The right formatting tools depend on your technical comfort level, budget, and publishing goals:
For zero learning curve: Reedsy Studio offers professional formatting in your browser with no download and no learning required.
For Word users: Draft2Digital converts Word documents to multiple formats with automated chapter detection and genre templates.
For Amazon-only publishing: Kindle Create provides the fastest path from Word to published Kindle book.
For format conversion: Calibre handles converting between any ebook format but requires patience with its learning curve.
For code-level control: Sigil gives complete EPUB editing power to authors comfortable with HTML and CSS.
For cross-platform professional formatting: Atticus delivers Vellum-quality results on any operating system with one-time pricing.
For premium design: Vellum produces the most beautiful books if you're on Mac and willing to invest.
For complete flexibility: Many authors use multiple tools in sequence—Reedsy Studio or Atticus for initial formatting, Sigil for fine-tuning specific EPUB elements, and Calibre for format conversion.
The key is matching tools to your publishing strategy. If you're publishing wide across multiple retailers, choose tools that export clean EPUB files. If you're KDP-exclusive, Kindle Create works perfectly. If you're building a long-term career with multiple books, investing in Atticus or Vellum pays off quickly.
Most importantly, remember that formatting is the bridge between your manuscript and your readers. Professional formatting doesn't draw attention to itself—it simply makes your book pleasant to read on any device. These tools handle the technical complexity so readers focus on your story, not on wonky spacing or broken chapter headings.
