CFF to SIX conversion is the process of transforming files in the CFF (Configurable File Format) container into the SIX (Structured Interchange eXchange) format, reorganizing data structures, metadata, and any embedded assets so they conform to the target schema. This conversion typically remaps CFF sections, normalizes metadata fields, and optionally applies compression or quality settings to produce a valid SIX package suitable for downstream tools and workflows.
