Vellum Review (2026): The Best Book Formatting Software for Mac?

What Is Vellum?

Vellum is book formatting software for Mac. That's it. It doesn't try to be a writing app, a cover designer, or an all-in-one publishing platform. It does one thing: takes your finished manuscript and turns it into professionally formatted ebook and print files.

It was built by Brad Andalman and Brad West at their company 180g. Both are former Pixar engineers, which goes some way to explaining why the app feels so polished. You import your manuscript from Word or Scrivener, pick a style theme, tweak the details, and export files ready for every major retailer.

Vellum is a formatter only. You write your book elsewhere, then bring it to Vellum for the final step. If you want a combined writing and formatting tool, that's not what this is.

What Vellum Does Well

The core workflow is genuinely excellent. You'll understand why people rave about it within five minutes of opening the app.

Import and setup

Drop in a .docx file from Word or Scrivener and Vellum automatically detects your chapter breaks, headings, and formatting. It's not perfect every time, but it gets close enough that cleanup is minimal. Most manuscripts import cleanly on the first try.

Style themes

There are 26 style themes to choose from, each with its own typography, chapter heading design, and ornamental elements. Romance authors tend to love the decorative options. Thriller writers go for the cleaner, bolder styles. You can preview any theme instantly and switch between them with one click.

Live preview

This is where Vellum really shines. You can preview your book exactly as it will appear on a Kindle Paperwhite, iPhone, iPad, or in print. Not a rough approximation. A pixel-accurate simulation. You see the actual reading experience your readers will have, which makes catching layout issues trivially easy.

One-click export

Hit the generate button and Vellum creates optimised files for Kindle, Apple Books, Kobo, Barnes & Noble, and generic EPUB, all in one go. Each file is tailored for its platform. No need to fiddle with separate export settings for each retailer.

Print formatting

Vellum handles print too, and handles it well. Choose from 24 trim sizes, including hardcover and large print options. Gutter widths, margins, and page numbering are all calculated automatically based on your page count. If you've ever wrestled with print formatting in Word, you'll appreciate how much pain this removes.

The details

Ornamental scene breaks, properly formatted footnotes (added in v3.7), verse formatting for poetry or song lyrics, four heading levels (v4.0), and a word count graph (v4.1). Vellum keeps adding useful features without bloating the interface.

The Free Trial Is Genuinely Useful

Most software trials are either time-limited or feature-limited in ways that make them useless. Vellum's approach is different and, frankly, better.

You download Vellum for free. You import your manuscript. You format the entire book. You preview it on every simulated device. You tweak everything until you're happy. The only thing you can't do without paying is export clean files. Trial exports are watermarked.

There's no time limit. You can sit with the trial for months if you want. This means you can make a fully informed decision about whether Vellum's output quality justifies the price before spending a penny. That's a confident move from the developers, and it tells you something about how good they think the product is.

Vellum Pricing

Vellum is a one-time purchase. No subscription, no annual fees, no per-book charges. You buy it once and use it for unlimited books forever.

Is that expensive? Compared to the competition, yes. Atticus costs $147 for everything. Reedsy Book Editor and Kindle Create are free. But if you publish regularly, Vellum's cost per book drops quickly. Format ten books and you're paying $25 each. Format fifty and it's $5.

The one-time model is genuinely appealing for prolific authors. No recurring costs eating into your margins year after year.

The Mac-Only Problem

This is the elephant in the room. Vellum only runs on Mac. No Windows version. No Linux version. No web app. If you don't own a Mac, you can't use Vellum. Full stop.

People have tried workarounds. The most common suggestion is MacInCloud, a service that lets you rent a Mac server remotely. But let's be honest about this: it costs $490 to $670 for the first year, it's slow, and multiple users report that you can't actually export files from Vellum through it. Most experts recommend against this approach. You'd be better off spending that money on a tool that actually runs on your computer.

If you're on Windows and want similar results, here are your realistic options:

The Mac-only restriction is the single biggest reason authors choose something else. It's not a minor inconvenience. It locks out roughly 75% of PC users worldwide.

Vellum vs Atticus

This is the comparison everyone searches for, and for good reason. Atticus is the most direct competitor to Vellum.

On pure typography and output polish, Vellum still wins. The ebook files it generates are beautiful. The print layouts are clean and professional. If output quality is your top priority and you're on a Mac, Vellum remains the best choice.

But Atticus is $103 cheaper, runs on everything, includes a writing editor, offers more templates, and handles nonfiction better. For most authors, that's a compelling package.

It's worth noting that Dave Chesson at Kindlepreneur, one of the most influential voices in the self-publishing space, switched his recommendation from Vellum to Atticus. His reasoning: too expensive versus the competition, limited customisation, and the Mac-only restriction. That shift carries weight in the community.

Who Vellum Is Perfect For

Vellum isn't for everyone, but for the right author, it's hard to beat.

• ✓Prolific fiction authors on Mac who publish multiple books a year. The one-time cost pays for itself quickly.
• ✓Authors publishing wide (not just Amazon). Vellum's one-click export for every major retailer saves real time.
• ✓Romance, thriller, and fantasy authors who want decorative chapter styles and ornamental elements that match their genre's visual expectations.
• ✓Anyone who values output quality above all else. If you want the absolute best-looking ebook files, Vellum is still the gold standard.

Who Should Look Elsewhere

• ✗Windows users. There's no workaround that's worth the hassle. Use Atticus, Reedsy, or Kindle Create instead.
• ✗Nonfiction authors with complex layouts. Textbooks, cookbooks, or anything with heavy image placement. Vellum's nonfiction support is limited.
• ✗Single-book authors. $250 is steep if you're only ever going to format one book. Reedsy is free and will get you 90% of the way there.
• ✗Budget-conscious beginners. If you're not sure self-publishing is for you yet, start with a free tool. You can always upgrade to Vellum later.

What Users Actually Say

The praise for Vellum is consistent and specific. Authors love the output quality. The ebooks look professional. The print files just work. The interface is clean and intuitive. You don't need to watch tutorials or read documentation to figure it out.

The complaints are equally consistent. Mac only. Expensive. Limited customisation compared to newer competitors. Can't tweak fonts or spacing the way you can in Atticus. No cloud sync, so you're tied to one machine unless you manually move files.

The Kindlepreneur shift is significant. For years, Dave Chesson recommended Vellum as the best formatting tool, full stop. His 2026 review is titled “Vellum Review: Why I Used to Recommend It (But No Longer Do)”. His reasons mirror what you'll hear across indie author communities: the competition has caught up on quality while offering more flexibility and lower prices.

The Bottom Line

Vellum is still the best book formatting software for output quality. That hasn't changed. The ebook files it produces are cleaner and more polished than anything else on the market.

But “best output” and “best value” are different things. At $250, Mac-only, with no writing editor and limited customisation, Vellum is a harder sell in 2026 than it was a few years ago. Atticus does 90% of what Vellum does at 60% of the price, on every platform.

If you're on a Mac and you publish fiction regularly, Vellum remains the gold standard. The try-before-you-buy model means there's zero risk in downloading it, formatting your book, and seeing the results for yourself. If the output quality convinces you, it's money well spent.

If you're on Windows, or you're watching your budget, or you only have one book to format, look at Atticus or Reedsy first.
