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.
PPM at a glance
PPM
Convert to PPM when a technical workflow needs a simple RGB raster format for processing, benchmarking, or intermediate conversion.
It is useful in command-line and research-oriented image pipelines.
