PEF at a glance
PEF
Convert to PEF when preserving Pentax camera originals or maintaining a Pentax-oriented raw workflow.
It is useful for archive masters and editable photographic captures.
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.
