EMF at a glance
EMF
Convert to EMF when placing vector graphics into Windows-centric documents, presentations, reporting systems, or print workflows that expect an Office-friendly scalable graphic.
It is suitable for charts, diagrams, and embedded illustrations in desktop-office environments.
For cross-platform web and design exchange, SVG or PDF are often better choices.
CRW at a glance
CRW
Convert to CRW when maintaining compatibility with older Canon raw libraries or recovering historical camera originals.
In most current workflows it is a source to preserve or migrate, not a preferred new output format.
