MOBI (Mobipocket) is an older eBook file format that was primarily used for Kindle eBooks before Amazon introduced the KF8/AZW3 format.
AZW3 (also known as KF8) is Amazon's newer Kindle Format 8 that offers enhanced formatting and layout capabilities over the older MOBI format.
Both MOBI and AZW3 formats are optimized for e-readers with reflowable text, but AZW3 offers better support for complex layouts, embedded fonts, and CSS styling.
Converting from MOBI to AZW3 allows you to maintain Kindle compatibility while gaining access to improved formatting features for a better reading experience.
AZW3 files support advanced features like drop caps, embedded fonts, and fixed layouts that aren't available in the older MOBI format.
Converting MOBI to AZW3 involves extracting the content structure of MOBI eBooks and reformatting it into the newer Kindle Format 8 structure.
AZW3 is based on HTML5 and CSS3 standards, allowing for richer formatting and layout options than the older MOBI format.
