When you upload your ebook to BookFunnel, there is a checkbox to include the KF8 when we distribute your MOBI.
What is a KF8?
Should You Include KF8?
That depends on what you are distributing. A few issues to consider:
- File size. If you check the KF8, your MOBI file will likely be double what it would be if we only delivered the older KF7 format. This is a non-issue for some fans, but for Android and Kindle Fire readers, a 4 MB book may be too large for them to squeeze onto their already-at-capacity local storage. Also, internet speeds are very slow in many parts of the world, and a larger file may prohibit some readers from downloading it
- Kindle For iOS app won’t show your KF8, even if you check the KF8 box. It can ONLY read the older MOBI format when a book is side loaded (meaning, distributed outside of the Kindle store). This means that your floopties and illustrations will not show up for any Kindle For iOS reader.
What will Kindle For iOS readers see?
