The Best Book Formatting Tools for Self-Publishers (2026)

Formatting is the step that turns a manuscript into a book: chapter headings, page numbers, margins, running heads, drop caps, scene breaks, a table of contents, and a clean EPUB that behaves on every reading app. A good tool makes it take hours instead of days, and saves you from the classic mistakes that get print files rejected. This guide compares the leading tools on price, platform, output and ease, with prices checked at each company's own site.

The tools at a glance

Prices checked October 2026 at each company's site.

LiberScript

LiberScript is a browser-based workspace that covers the whole path from draft to files: you write or import your manuscript, get an AI-assisted critique, design the interior, and export print-ready PDF, EPUB and DOCX. Because it runs in the browser, it works on Windows, Mac, Linux and Chromebooks alike. Its plans are time-based: $3.99 for a day, $9.99 for a week, $29.99 for a month, $99.99 for a year, or $299.99 for lifetime access. That makes it inexpensive if you format one book in a focused week, and good value if you write several books a year.

Best for: authors who want writing, feedback and formatting in one place, on any computer, without a large upfront payment. LiberScript also offers done-for-you editing, formatting and cover design if you'd rather hand the work over.

Atticus

Atticus is a writing and formatting app for $147, paid once, with all future updates included and a 30-day money-back guarantee. It runs on Windows, Mac, Linux and Chromebook, and in a browser on any desktop or tablet, and it works offline as a progressive web app. It produces ebooks and print-ready PDFs from themes you can customise.

Best for: authors who want a one-time purchase, work across several devices, and publish several books.

Vellum

Vellum is long regarded as the most polished formatting app for novels, with beautiful built-in styles. It runs only on macOS. Vellum Ebooks costs $199.99 and creates unlimited ebooks; Vellum Press costs $249.99 and adds paperbacks. You can download it free and try it on your book, but you must buy it to generate files for publishing.

Best for: Mac users who publish many novels and value elegant typography with very little effort.

Kindle Create

Kindle Create is Amazon's free formatting tool for Windows and Mac. It turns a manuscript into a Kindle ebook, exporting Amazon's KPF format or EPUB, and can format paperbacks, calculating margins automatically and adding page numbers. It supports reflowable books, print replica books and comics.

Best for: authors publishing mainly on Amazon who want a free tool. Its KPF files are built for Kindle, so for other stores, export EPUB or use another tool.

Reedsy Studio

Reedsy Studio, formerly the Reedsy Book Editor, is a free online app for writing and formatting. It exports a reflowable EPUB 3 and a print-ready PDF designed for print-on-demand services, with three free templates (Classic, Romance and Reedsy) and four trim sizes: 6 x 9, 5.5 x 8.5, 5 x 8 and 4.25 x 6.87 inches.

Best for: authors on a tight budget with a straightforward book who are happy with a small set of templates.

Microsoft Word

Many books have been formatted in Word, and KDP publishes Word templates. It gives you full control, but it's easy to make mistakes: manual spacing instead of styles, missing section breaks, headers that repeat on chapter openings. Ebooks usually need converting from Word, which can bring stray formatting along. See formatting an ebook from Word if you go this route.

Best for: simple books, authors who already know Word's styles well, or anyone who needs to deliver a DOCX to an editor.

How to choose

What good formatting gets right

• Margins and gutter that suit your trim size and page count, so text never disappears into the spine. See book print margins.
• Chapter openings without running heads or page numbers where they don't belong.
• Consistent styles for headings, body text, scene breaks and block quotes.
• A working table of contents in the ebook, and page numbers in print.
• Clean EPUB structure, so the ebook reflows properly on every device and in every app.
• Front and back matter in the right order: title page, copyright, dedication, and at the back, a link to your next book.

What each costs over time

The pricing models differ enough that the cheapest tool depends on how you work. A one-time purchase like Atticus ($147) or Vellum ($199.99 or $249.99) costs the most upfront but nothing more for future books. LiberScript's time-based plans cost little for a single focused project, $9.99 for a week of formatting, and its annual and lifetime plans suit authors who write steadily. Free tools cost nothing but may limit templates or stores.

A simple way to decide: estimate how many books you'll format over the next two or three years, and how much time each tool would save you. For one book, a free tool or a short plan is hard to beat. For a long series, a tool that makes every book faster and more consistent quickly pays for itself.

Testing before you commit

Every tool looks good in its demo. Before you commit, take your hardest chapter, one with images, tables, footnotes or unusual layout, and run it through the tool. Export both an EPUB and a print PDF. Open the EPUB in two or three reading apps, and check the PDF at your trim size, looking closely at margins, headers and page breaks. Most tools offer a trial, a free tier or a refund window; use it.

Print files: the part that trips people up

Ebooks are forgiving; print isn't. A print interior must be exactly the trim size (or include bleed if artwork runs to the edge), with margins large enough for your page count, and fonts embedded. The cover is a separate full-wrap file whose width depends on your final page count. Whatever tool you use, finish the interior first, then build the cover from your printer's template. See book trim sizes and book spine width.

Ebook files: small details that matter

A reflowable EPUB adapts to every screen size, font size and reading app, so fixed spacing, manual line breaks and oversized images cause problems. Good tools build the EPUB from styles, keep images to sensible sizes and generate a navigable table of contents. Always preview the file on a phone as well as a tablet. Readers notice a broken table of contents or a chapter heading stranded at the bottom of a screen, and those small things show up in reviews.

Where BooksOasis fits

BooksOasis doesn't format books, but it accepts the standard files every tool here can produce: an EPUB for the ebook, and an interior PDF and a full-wrap cover PDF for each print edition. When you upload a print interior, BooksOasis reads the page count from it, quotes the printing cost, shows the exact cover size and spine width, and offers a downloadable cover template. An automatic print-readiness check tests both files before your book goes to review, and Preview shows the cover laid out with every zone marked and the interior as printed spreads.

Three authors, three tools

A romance author on a Mac publishing six books a year uses Vellum Press for its polished styles and speed.

A non-fiction author on a Windows laptop and a Chromebook writes and formats in LiberScript, using its critique before final formatting, and exports EPUB and print PDF for every store.

A first-time author with a simple novel and no budget formats in Reedsy Studio and uploads the EPUB and print PDF to BooksOasis and other stores.
