More about the EPUB to AZW3 Converter
MOBI, the older Kindle ebook format, gets text onto a device fine but drops some finer formatting, an embedded font, a fixed layout for something like a graphic novel, more elaborate CSS styling, while AZW3, the newer Kindle format also called KF8, actually preserves that detail on a modern Kindle app or device. This tool converts an EPUB ebook into AZW3, keeping formatting that would otherwise be simplified away by an older format. Useful for converting a self-published EPUB into AZW3 so a modern Kindle app renders its custom fonts and layout correctly, preparing an illustrated or fixed-layout EPUB for Kindle without losing its formatting, or moving an EPUB library onto a Kindle device in the more capable of its two native formats.
