What is CGM?

Computer Graphics Metafile (CGM) is a vector and raster graphics format for technical illustrations and engineering diagrams.

What is RAW?

Camera RAW is a file format containing unprocessed sensor data captured directly from a digital camera sensor, providing maximum flexibility for professional photo editing.

When Should You Use CGM vs RAW?

Use CGM When...

Reach for CGM when your priority is technical illustrations, engineering diagrams — its uncompromising quality ensures every detail is preserved.

Reach for RAW when your priority is professional photography, post-processing, editing — its uncompromising quality ensures every detail is preserved.

CGM vs RAW: Key Differences

  • •CGM uses lossless compression while RAW uses lossless compression — both take the same approach to file size management.
  • •Since both CGM and RAW use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •How transparency is handled: RAW supports transparency, so alpha information is preserved during conversion.
  • •CGM files are typically Compact for vector drawings while RAW files range 20-50MB per photo depending on camera
  • •Primary audience: CGM is built for technical illustrations, engineering diagrams scenarios, while RAW focuses on professional photography, post-processing, editing — pick the format that matches your output requirement.

Best Practices for CGM to RAW Conversion

  • →Before converting CGM to RAW, decide whether you need maximum quality or smallest file size — this determines which format truly fits
  • →Save a master copy in a lossless format before converting to RAW — you cannot recover detail lost during lossy compression
  • →Check the color profile: CGM images may use a wider gamut than RAW supports, causing a visible shift after conversion
  • →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
  • →Run a single test conversion first to verify quality meets your standards
  • →Strip unnecessary metadata to reduce file size after conversion

Troubleshooting CGM to RAW Conversion

  • !Converting CGM to RAW gives blurry output → increase the quality setting before conversion
  • !Colors look different in RAW than CGM → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → RAW uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in CGM turned white in RAW → RAW may not support transparency
