The settings in this section control how your project is exported to the ePUB and Kindle/Mobi eBooks formats. Kindle/Mobi is the standard format for Amazon Kindle eBooks and allows you to distribute your eBooks directly through Amazon. The ePUB eBook format is now the leading universal open format for eBooks. The ePUB 3.0 eBooks generated by Help+Manual are compatible with all ePUB hardware and software readers. However, they also contain the additional special configuration and formatting information for display on Apple iOS devices (iPad, iPhone and iPod Touch).
