PNM in sintesi
PNM
Convert to PNM when you need a plain, easily processed raster format for scripts, research, or utility pipelines.
It is useful as an intermediate representation in technical imaging workflows.
CDR in sintesi
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.

What changes when converting PNM to CDR?
This conversion changes how the format behaves in downstream tools and delivery environments.
Size profile changes from medium in PNM to small in CDR. Quality profile changes from depends in PNM to scalable in CDR. Editability profile changes from moderate in PNM to high in CDR. Compatibility profile changes from broad in PNM to moderate in CDR. Archival profile changes from moderate in PNM to good in CDR. Workflow profile changes from delivery in PNM to design in CDR.
Moving to CDR adds vector scaling.
What should I review after converting PNM to CDR?
Check the exported file for Proprietary with no publicly available format specification.; Limited cross-application compatibility.; Older versions not fully readable by newer editors..
