If you’ve recently uploaded an ebook to KDP, you may have noticed a change. Amazon now recommends providing an EPUB file for publishing instead of a file in their MOBI format. MOBI files are still supported, but if you open one in Kindle Previewer, you will see the following warning:
We imagine there may be some questions about this change. Here are some answers:
Q. Can Vellum produce an EPUB file for Amazon? A. Yes! 🎉 You can change the format used for Kindle in Preferences. Vellum will produce an EPUB file that is designed for Kindle, and won’t result in any warnings from Kindle Previewer. Generating an EPUB file is also much faster than relying on Amazon’s conversion tools.
Q. Can I just send Vellum’s Generic EPUB to Amazon? A. No! 😱 Don’t do that! Any Store Links will likely be wrong, and you may see issues in Amazon services like Look Inside and Kindle Cloud Reader.
Q. Can I still upload a MOBI file? A. You can. Though they recommend providing an EPUB, Amazon still lists MOBI as a supported format.
Q. Is Amazon now sending EPUB files to customers? A. No. Files delivered to customers use Amazon’s format for Enhanced Typesetting. Amazon converts your ebook to this format after you upload to KDP.
Q. Can I load an EPUB file onto my Kindle? A. No. Unfortunately, you will still need a MOBI file to sideload onto your Kindle or to send to a reader with a Kindle. (If you make use of BookFunnel, they can take care of this conversion for you.)
Q. Will Vellum stop producing MOBI files? A. No. Don’t worry. But given Amazon’s new recommendations, we are considering solutions such as generating both Kindle EPUB and MOBI files. As long as Amazon keeps the necessary conversion tools available, we will continue to provide MOBI as an option.
Announcing Internal Links! You’ll find them in Vellum 2.7 with a whole lot more:
You can now create Internal Links, which direct a reader to a different section of your ebook. Use an Internal Link to refer to another chapter, to provide quick access to a glossary or a map, or even to build an interactive narrative.
You can add Internal Links within Vellum, or import links you’ve established in your Word file.
New Options for Your TOC
If you’ve organized your chapters using Subheads, you can now list them in the Table of Contents. Include Subtitles for your Chapters, Parts, and Volumes as well. And if you’re creating an anthology, you can now credit story Authors in the TOC.
After receiving feedback from our users, we’re announcing that in our next update, Vellum will return to generating mobi files for the Kindle platform.
Vellum recently moved away from creating files in the mobi format, as the KindleGen utility that Vellum used to convert these files is not compatible with the forthcoming version of macOS. To generate mobi files in a manner that works with macOS Catalina, Vellum will switch to use conversion tools bundled with Amazon’s Kindle Previewer utility.
Because we have also received some positive feedback about the new Kindle.epub files, generating Kindle-specific EPUB will remain as an option. This option will also serve as a fallback in case the conversion tools in Kindle Previewer fail in the future.
This update is currently planned for October 2. In the meantime, if you need to convert Kindle.epub files to the mobi format, you can do so by opening your file in Kindle Previewer and using the Export option. If you have any questions, please contact us.
