Vellum vs Atticus — quick overview
In the Vellum vs Atticus comparison, the single most important factor is your operating system. Vellum is Mac only. Atticus runs on Windows, Mac, Linux, and in any web browser. If you are on Windows, the decision is already made for you — Atticus is your only realistic option between the two. If you are on Mac, however, both are available and the comparison becomes more nuanced.
Vellum in depth
Vellum is widely regarded as the gold standard for ebook formatting among indie authors. The interface is clean and intuitive, the themes are visually polished, and the EPUB output is consistently excellent across Kindle, Apple Books, and Kobo. Authors who use Vellum tend to stay with Vellum because the experience is genuinely pleasant.
Vellum pricing
Vellum uses a one-time fee model with two tiers. Vellum Ebooks costs $199.99 and covers unlimited ebook production. Vellum Press, which adds print book formatting, costs $249.99. For authors who plan to publish multiple books, the cost per book decreases quickly. For a first-time author producing a single book, it is a more significant upfront commitment.
Vellum ebook output quality
Vellum’s ebook output is genuinely outstanding. The EPUB files are clean, well-structured, and render beautifully across all major platforms. The theme library covers most fiction genres with elegant chapter ornaments, drop caps, and typographic detail that gives books a premium feel. Consequently, many authors choose Vellum specifically because the reading experience it creates matches the emotional tone of their book.
Vellum’s main limitation
The limitation is absolute: Vellum only runs on Mac. There is no Windows version and no credible indication one is coming. If you are on Windows, you cannot use Vellum without either buying a Mac, renting cloud Mac access via a service like MacinCloud, or using a virtual machine. For most authors, these workarounds add complexity and cost that negate Vellum’s advantages.
Atticus in depth
Atticus launched specifically to address Vellum’s biggest weakness. It runs on Windows, Mac, Linux, and in a web browser, which means any author on any device can use it. At $147 as a one-time purchase, it also costs less than Vellum and includes both print and ebook formatting with no ongoing fees.
Atticus features and quality
Atticus has improved steadily since launch and now produces results that are completely professional for most standard use cases. The theme library has expanded, the print output is solid, and the ebook formatting quality is strong enough that readers will not notice any difference from Vellum in most genres. Furthermore, Atticus includes a built-in writing environment, though most authors still prefer to write in Word or Scrivener and import for formatting.
Where Atticus falls slightly short
In the Vellum vs Atticus comparison, Vellum still edges Atticus on the purely aesthetic quality of its ebook themes and typography control. The difference is noticeable if you place the two outputs side by side. However, for most authors producing standard genre fiction or straightforward non-fiction, the gap is not significant enough to justify switching platforms or paying the higher price. Atticus is very good. Vellum is slightly better-looking. Whether that matters depends on your book and your standards.

What about Scrivener and Microsoft Word?
Scrivener
Scrivener is a writing tool, not a formatting tool. It does have ebook export options, but the files it produces often have structural inconsistencies that only become apparent on certain devices. As a result, the best workflow for Scrivener users is to write in Scrivener, export to Word, clean up the file there, and then import into Vellum or Atticus for final formatting. That approach gives you the best output from whichever formatting tool you choose.
Microsoft Word
You can produce a functional print-ready PDF directly in Microsoft Word if you set up your document correctly from the start — right page size, correct margins, proper heading styles, and paragraph formatting applied through styles rather than manual formatting. The results are not as visually polished as Vellum or Atticus. However, they are entirely professional and indistinguishable from other print books in most non-fiction genres. Word is most viable for non-fiction authors whose books do not need strong design personality.
Which one should you buy?
Buy Atticus if…
You are on Windows — this is the clear answer. You are on Mac but publishing your first book and want to keep costs down. You want both print and ebook formatting included in one lower price. You want the flexibility to format on any device or operating system. Atticus handles all standard book types completely professionally and you will be proud of the results.
Buy Vellum if…
You are on Mac and planning to publish multiple books — the per-book cost drops quickly. You write genre fiction where ebook visual quality matters to readers and reviewers. You want the absolute best ebook output available from a DIY tool. You are building a publishing catalogue over multiple years and the one-time investment makes clear financial sense.
When neither Vellum nor Atticus is enough
Both Vellum and Atticus have limitations when books get complex. Specifically, illustrated non-fiction with images throughout, cookbooks, children’s books, heavily designed business books, books with tables and charts, and titles requiring custom typography all present challenges for DIY formatting tools. In those cases, the output from either tool is often not sufficient for professional publication.
Moreover, even for standard books, some authors simply prefer not to deal with the technical aspects of formatting at all. Our publishing team at XpressPublisher handles formatting for all genres across the USA and UK — print-ready PDF and clean EPUB both verified against KDP and IngramSpark specifications. If you are unsure whether your book needs professional formatting or whether a DIY tool will handle it, send us your details and we will give you an honest answer with no pressure.

Frequently asked questions about Vellum vs Atticus
Is Vellum better than Atticus?
Vellum produces slightly more polished ebook output and has a larger, more refined theme library. However, Atticus is cross-platform, costs less, and includes print formatting in its base price. For most authors, Atticus is better value. For Mac users publishing multiple books who prioritise ebook aesthetics, Vellum is worth the premium.
Can I use Vellum on Windows?
No. Vellum is Mac only with no Windows version available. Windows authors should use Atticus, which is a fully capable alternative that runs on any operating system including Windows, Mac, Linux, and web browsers.
How much does Atticus cost compared to Vellum?
Atticus costs $147 as a one-time purchase and includes both ebook and print formatting. Vellum costs $199.99 for ebooks only or $249.99 for ebooks and print. Therefore, Atticus is $100 cheaper than Vellum Press for the equivalent feature set covering both formats.
Which is better for print book formatting?
Both produce solid print output for standard novels and non-fiction. Vellum’s print formatting is included in Vellum Press at $249.99. Atticus includes print formatting in its standard $147 price. For highly designed non-fiction with images, tables, or complex layouts, neither tool is ideal and professional formatting is worth considering instead.
Does Atticus produce files that work on Amazon KDP and IngramSpark?
Yes. Atticus produces EPUB files for ebooks and PDF files for print that are compatible with both Amazon KDP and IngramSpark. However, IngramSpark has stricter file specifications than KDP. As a result, always verify your files against IngramSpark’s requirements before submitting, particularly for print books over 300 pages.
Can I switch from Vellum to Atticus later?
Yes. Both tools work from your original Word or Scrivener manuscript file. Consequently, switching between them is straightforward — you simply import your manuscript into the new tool and apply a new theme. Your previously formatted files remain unchanged and you can maintain both tools simultaneously if needed.
