ELECTRONIC Publication to SIX conversion is the process of transforming an EPUB (a widely used, reflowable e-book container that stores HTML, CSS, images and metadata) into the SIX format, producing a document packaged and optimized for the SIX reader or workflow. This conversion extracts and maps text, images, styles, and structure from the EPUB container into SIX’s expected file organization and settings so the resulting file preserves reading order, navigation, and visual fidelity.
