RB at a glance
RB
Convert to RB only when preserving or reproducing legacy Rocket eBook collections or working inside an archival reconstruction workflow.
In normal publishing practice, RB content is usually migrated into EPUB or Kindle-oriented formats.
It is a heritage compatibility target, not a modern distribution format.
CDR at a glance
CDR
Convert to CDR when the recipient will continue editing or producing the artwork in CorelDRAW-based environments, especially in print, signage, or fabrication-adjacent workflows.
It is useful when native Corel compatibility is the priority.
For more neutral exchange, PDF, SVG, or EPS are usually easier handoff formats.
