Vellum
Vellum is a Mac app for writing, formatting, and exporting professional ebooks and print books for self-publishing workflows.
What is Vellum?
Vellum is a native Mac book-production app that helps authors turn manuscripts into polished ebooks and print-ready books. It is designed for self-publishers, independent authors, and small publishing teams that want to format books without doing manual layout work in a general-purpose word processor. Users can import a manuscript, organize front and back matter, style chapter pages, and preview how the finished book will look across common reading formats. Vellum supports creating files for major ebook stores as well as print output, making it useful when preparing the same title for multiple publishing channels. The app is Mac-only, with current versions supporting modern macOS releases and legacy downloads available for older systems from the publisher.

Safety overview
Status: Safe
Vellum is legitimate publishing software for macOS. It works with manuscripts and exported book files, so the main privacy consideration is the content of the documents you open and generate. Removing the app will stop access to its editing and export tools, but your saved manuscript and book project files remain your own files if you keep them backed up. If you rely on Vellum for active publishing work, keep your project files and exported books in a separate backup location before making changes.
Recommendation: Keep Vellum if you write, format, or publish books on your Mac. If you no longer use it, you can remove the app after confirming your project files and exported books are backed up elsewhere.
