Vellum is a powerful self-publishing software designed for authors, aiming to easily convert manuscripts into professionally formatted and high-quality eBooks. It offers a wide range of style and layout options and supports importing content from various file formats such as Microsoft Word and Scrivener. Additionally, it synchronizes metadata with platforms like Kindle Direct Publishing, significantly simplifying the publishing process.
Vellum supports generating professional eBook files for platforms like Kindle, Kobo, and Apple Books, each containing links to purchase series books. For series works, users can quickly create collection eBooks with a few simple operations.
Users only need to select the crop size, and Vellum will automatically handle margin, page numbers, and header/footer settings. The software can also handle complex layout tasks like widows and orphans intelligently, ensuring that each printed file meets the publishing standards.
Vellum provides rich style customization features, including:
Users can choose from a variety of book styles and the selected style will be automatically synchronized across all chapters (including future chapters added). The real-time preview feature allows users to see the display effects of the eBook on different devices and the layout of printed files in real-time, with all edits reflecting in the preview.
After editing, both the eBook and print files can be generated simultaneously, and they remain synchronized. If corrections are needed, simply updating the original manuscript in Vellum can generate the entire set of files in a matter of seconds, greatly improving the revision efficiency.
This version mainly fixed several issues that appeared in the macOS Sonoma system, including:


The installation process for Vellum for Mac v3.5.4 is straightforward, but to ensure smooth operation, it is recommended to follow the steps below. We have tested the software on macOS Ventura and Sonoma systems, and it works normally.
First, ensure your Mac meets the minimum system requirements: macOS 11.0 (Big Sur) or a higher version. Reserve at least 500 MB of hard disk space. Additionally, disabling System Integrity Protection (SIP) is not mandatory, but if you encounter permission issues, you can temporarily disable it.
From the provided link on this page, download Vellum for Mac v3.5.4 Activation Version. After downloading, double-click the .dmg file to mount it. Then, drag the Vellum icon to the “Applications” folder. This process is similar to installing most Mac software.
Enter the “Applications” folder, double-click the Vellum icon to launch it. If the system prompts “Unable to verify developer identity,” go to “System Preferences” -> “Security & Privacy” -> “General,” and click “Open.” After the first launch, the software will automatically detect the activation status. Since this version is integrated with an activation patch, you do not need to manually input a serial number.
After launching, click “Vellum” -> “About Vellum” to confirm the version number is 3.5.4. Then, try creating a new project and importing a Word document to test. If all functions work properly, the installation is successful.
If you encounter the “Installer is damaged” prompt during the installation process, check the integrity of the downloaded file or try re-downloading it. Another common issue is insufficient permissions. You can resolve this by entering the terminal command sudo xattr -rd com.apple.quarantine /Applications/Vellum.app.
Yes, Vellum handles Chinese well, including automatic handling of initial indentation and hanging punctuation (like quotation marks and book titles) in Chinese. It is recommended to set the font to SimSun or SimHei in the Word document before importing to achieve the best display effect.
First, ensure you have selected the correct output format (e.g., .mobi or .epub) in Vellum. Next, check the font settings on your Kindle device. Some custom fonts may not be supported by Kindle. It is recommended to use the default font. Finally, use Vellum’s real-time preview feature to check the Kindle simulator view before generating the file.
Vellum supports importing Scrivener project files (e.g., .scriv). Simply click “File” -> “Import” -> “Scrivener Project,” and select your .scriv file. Vellum will automatically retain the chapter structure and most formatting, but it is recommended to check the consistency of the styles after importing.
The activated version provided on this page is based on v3.5.4. Typically, activation patches are only applicable to the current version. If you wish to update to a future version, you may need to wait for a new activated version to be released. It is recommended to keep an eye on this site for the latest version information.
Yes. Vellum not only generates e-books but also PDF files that meet printing standards. In the “Generate” interface, select the “Print” tab and choose the crop size (such as 6×9 inches). The software will automatically add bleed areas, page numbers, and book margins.
First, ensure your Mac is updated to the latest version. Next, check if other large applications (such as Photoshop) are running simultaneously. Vellum has memory requirements; it is recommended to close unnecessary background applications. If the issue persists, try restarting the software or reinstalling it.
Vellum supports using system fonts. You simply need to install the font files (.ttf or .otf) to the Mac’s “Font Book” and then select the font in Vellum’s style settings. Note that if you want to embed the font into the e-book, ensure the font license allows embedding.
Please check the format and size of the cover image. Vellum recommends using JPEG or PNG format, with a minimum size of 1400×2100 pixels. Re-upload the cover in the “Book Settings” -> “Cover” and regenerate the file. If the issue persists, try converting the cover image to the RGB color mode.
Mastering shortcuts can significantly enhance your layout efficiency. The table below lists the most commonly used shortcuts in Vellum, covering editing, navigation, and layout operations.

| Command + O | Open an existing project |

Many novice authors manually adjust the formatting for titles and body text in each chapter, which is very time-consuming. Vellum’s “Style Sets” feature can solve this problem. You simply need to set the styles for titles, body text, and citations in the first chapter, then click the “Style” menu and save the style set. When creating new chapters, directly apply the style set, and all formats will be automatically unified. According to a survey by The Publishers Weekly, using style sets can save about 40% of the layout time.
Within self-publishing, image layout is a common pain point. Vellum offers “inline” and “floated” image modes. For decorative illustrations in novels, it is recommended to use the “inline” mode, allowing the images to flow with the text. For technical books with charts, using the “floated” mode and setting alignment can avoid images breaking across pages. Before importing, set the image resolution to 300 DPI to ensure print quality.
Assume you have a 100,000-word Word manuscript, aiming to publish it to Amazon’s Kindle platform. First, clean up the formatting in Word, retaining only basic heading and paragraph styles. Then, in Vellum, create a new project and import the Word file. Next, use the “Style Set” to quickly apply the “novel” template. Utilize the real-time preview feature to check the reading experience on an iPhone and Kindle simulator. Finally, in the generation interface, select “Kindle (.mobi)” and click “Generate.” The entire process takes about 15 minutes, significantly improving efficiency compared to traditional layout software.
Vellum supports adding rich metadata to e-books, including author names, book titles, descriptions, and keywords. These details directly impact the search rankings of books on platforms like Amazon. It is recommended to fill out the “Metadata” section in “Book Settings” with 7-10 precise long-tail keywords. For instance, if your book is a science fiction novel, you could use “Space Opera,” “Interstellar War,” or “Artificial Intelligence Awakening.” According to Amazon’s guidelines, optimizing metadata can increase exposure by over 30%.
Academic authors often need to handle numerous footnotes. Vellum’s footnote feature is very intelligent. You simply insert footnote markers in the text, and Vellum automatically generates a footnote list at the end of each chapter. The key is that Vellum’s footnotes are clickable and jumpable in e-book readers. Before generating, make sure the footnote numbers are continuous. If you find skipping numbers, it is usually due to lost formatting when importing, and you can manually adjust them.
Vellum for Mac v3.5.4 is a truly customized tool for self-publishing authors. It significantly lowers the barriers to e-book creation through full-platform support, automated layout, and real-time preview. Whether you are a novelist, academic researcher, or business writer, Vellum can help you transform your manuscript into a professional-grade work. Our activation version has been rigorously tested to ensure stable operation on the macOS Sonoma system.
