Primary use cases	Exchange of vector artwork between Corel applications, clipart libraries, and print/prepress workflows

What is the CMX file format?

CMX is a Corel Presentation Exchange metafile used to exchange vector artwork (and embedded bitmaps) between Corel applications.

CMX file characteristics

Data type	Vector image (metafile)
MIME type	image/x-cmx
Structure type	RIFF-based chunked metafile
Container format	RIFF/RIFX container (little-/big-endian variants) storing Corel drawing primitives; can include embedded raster images
Metadata	May include palette/spot-color definitions, object/layer properties, and other application-specific metadata
Standard / Specification	No formal open standard; RIFF-based Corel CMX format
Typical file size	Usually small for vector-only art; can grow significantly with embedded high-resolution bitmaps

Advantages

The CMX file format offers several advantages that make it suitable for common use cases.

Preserves scalable vector objects;
Can include layers and embedded bitmaps;
Supports CMYK and spot colors in Corel workflows

Limitations

The CMX file format has certain limitations that may affect its use in specific scenarios.

Feature support varies by CMX version and importer;
Complex effects may not round-trip perfectly through third-party converters

Compatibility

CMX vector files are supported by a wide range of design and graphics applications.

Supported platforms: CorelDRAW/PHOTO-PAINT on Windows and macOS; limited import via third-party tools (e.g., LibreOffice via libcdr)
Supported devices: Computers; print/prepress devices via export to standard formats
Browser support: No
Mobile support: No
Backward compatibility: Yes

Security considerations

Treat CMX as untrusted input: complex parsers exist and malformed files can trigger crashes in importers. Convert in a sandbox and keep software updated.
