EPUB (Electronic Publication) is an open e-book format that uses HTML, CSS, and XML technology, making it responsive to different screen sizes.
MOBI (Mobipocket) is Amazon's proprietary e-book format, specifically designed for Kindle e-readers and apps.
While EPUB files provide a better reading experience on most e-readers with reflowable text, MOBI files are essential for Kindle devices which don't natively support EPUB.
Converting from EPUB to MOBI creates a document that can be easily viewed on Kindle e-readers, Kindle apps, and other devices supporting the MOBI format.
MOBI files support many of the same features as EPUB, including bookmarks, annotations, and a table of contents, making them ideal for Kindle users.
Converting EPUB to MOBI involves translating the EPUB's XHTML/CSS components into MOBI's proprietary format while maintaining the content structure.
MOBI conversion tools typically use libraries like Amazon's KindleGen, Calibre's engine, or other specialized rendering engines to interpret the content and styling.
During conversion, the reflowable EPUB content must be reformatted to match MOBI specifications for text flow, images, and navigation.
Advanced converters preserve hyperlinks, table of contents, embedded fonts, and images while adapting them to MOBI's document structure.
While EPUB supports some advanced features, MOBI conversion focuses on ensuring the content is compatible with Amazon's ecosystem while maintaining readability.
