Vellum on your Mac — 4.1.7

Vellum 4.1.5 EDiSO supports Kindle, Kobo, and Apple Books output, plus print editions. That’s three ebook formats and a paper-ready layout from one Mac app. It imports a manuscript or starts from scratch, generating a title page and table of contents automatically. The preview updates instantly while you edit, showing how each chapter looks on different devices or in print. It also handles widows and spread balancing for a polished result. Boxed sets are possible, combining multiple books into one volume. The Mac app is described as native and runs on both Intel and Apple Silicon systems.

Can I use Vellum without an internet connection?

Yes. Vellum runs entirely on your Mac once installed. No constant internet is required for editing, previewing, or applying chapter styles.

Does Vellum work with my existing manuscript file?

It imports a manuscript and builds a title page and table of contents from it. You can also create a new book from scratch inside the app.

Indie authors and small presses who need control over final formatting

Vellum suits writers who want control over final formatting without learning page‑layout software. Indie authors publishing on multiple platforms are the obvious fit, but the app also helps small presses that manage several titles at once. Because it generates Kindle, Kobo, and Apple Books files from one project, you avoid converting the same manuscript three separate times. That matters if you routinely update your book and re‑upload to each store.

Fiction writers who use chapter breaks and consistent heading styles find Vellum especially useful. The app applies the chosen style to each chapter, including newly added ones, which saves checking every section manually. Non‑fiction authors with many sub‑sections benefit from the same feature, though Vellum works best when you stick to a simple chapter structure.

Anyone who publishes both ebook and print editions will appreciate the single‑project workflow. You choose a trim size, and margins, page numbers, headers, and footers adjust automatically. That eliminates the back‑and‑forth of formatting a print edition separately. Teachers running small‑press projects through a school club or workshop have told me it reduces prep time considerably.

Indie author scenario: Sarah’s series update

Sarah publishes a three‑book fantasy series and wants a boxed set for a promotion. She has each book as a separate Vellum project. She opens the boxed‑set feature, selects the three projects, and Vellum combines them into one volume with a new title page and table of contents. She adds a copyright page inside the app. After the promotion, she edits chapter 5 of the second book to fix a typo. She regenerates the ebook files for Kindle, Kobo, and Apple Books with one click, and the updates appear in the same boxed‑set file. She never re‑imports or re‑links the books.

The same workflow applies if you update a single book and republish across stores. Vellum regenerates updated ebook files after changes, so you keep one master file and push revisions out quickly.

Requires macOS 11 or later and runs on both Apple Silicon and Intel Macs

Vellum 4.1.5 EDiSO requires macOS 11 or later. It supports both Apple Silicon and Intel 64‑bit Macs, so it runs on older Intel models and newer ARM ones alike. The app is described as native, which means it uses your system’s resources directly rather than through emulation. The installer comes as a disk image you mount, then drag the app into the Applications folder alias. After the copy finishes, you can open it from Launchpad.

The interface is in English. There are no separate language packs or regional settings. The app’s preview panel updates instantly while you edit, so you see formatting changes as you type rather than after a manual refresh. That matters when you adjust margins or check widows on a long chapter. The print preview shows how page numbers, headers, and footers land on each page, giving you a clear look before exporting.

Vellum generates finished ebooks without the manual styling needed in Scrivener

Vellum competes with Scrivener, Jutoh, and Reedsy Studio. Scrivener handles drafting and organization but exports ebooks through compile settings that require manual styling. You get a manuscript tool, not a dedicated formatter, so you spend extra time adjusting output. Vellum focuses purely on formatting and generates store‑ready files directly.

Jutoh is another dedicated ebook formatter. It offers more granular control over CSS and metadata but has a steeper learning curve. Its preview is less immediate than Vellum’s real‑time preview. Jutoh runs on Windows and Linux too, while Vellum is Mac‑only, which matters if your team uses other operating systems.

Reedsy Studio is a free browser‑based tool. It handles basic ebook formatting but requires an internet connection for every edit. It supports Kindle and Kobo output but not Apple Books directly. Vellum runs offline once installed and supports Apple Books natively. Reedsy Studio also lacks print edition support, so you cannot generate both formats from the same project. If you publish paperbacks too, Vellum saves you from maintaining two separate files.

None of these apps is a full desktop‑publishing replacement. They all focus on reflowable ebooks and standard print layouts. Vellum’s advantage is the combination of instant preview, multi‑format output, and boxed‑set creation in one native Mac app. For authors who publish regularly, the time saved on formatting usually justifies the switch.
