ABW to AZW3 conversion is the process of transforming a document saved in AbiWord's native ABW format into Amazon Kindle's AZW3 (KF8) ebook format so it can be read on Kindle devices and apps. This conversion maps ABW text, basic formatting, images and metadata into the AZW3 structure while adapting layout and styles for reflowable ebook presentation.
