MOBIPOCKET Books to RGBO conversion is the process of transforming eBook files in the MOBI format (created by Mobipocket and used by many Kindle devices and apps) into the RGBO document format, which preserves textual structure and rendering options for applications that support RGBO. This conversion extracts the book's text, metadata, images and basic layout from MOBI and repackages them into RGBO while attempting to maintain readability and chapter/heading structure.
