What is HDR?

Radiance HDR is an image format that stores high dynamic range pixel data, commonly used for HDRI environment maps and lighting.

What is CGM?

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

When Should You Use HDR vs CGM?

Use HDR When...

Reach for HDR when your priority is hdri lighting, panoramic photography — its uncompromising quality ensures every detail is preserved.

Use CGM When...

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

HDR vs CGM: Key Differences

•HDR and CGM diverge on compression: lossless compression for the source, lossless compression for the target.
•Since both HDR and CGM use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
•Transparency: N/A
•HDR files are typically 5-30MB for typical HDR maps while CGM files range Compact for vector drawings
•Primary audience: HDR is built for hdri lighting, panoramic photography scenarios, while CGM focuses on technical illustrations, engineering diagrams — pick the format that matches your output requirement.

Advantages of HDR

✓HDR uses lossless compression tailored for HDRI lighting, panoramic photography.
✓HDR is supported natively on virtually every device, browser, and operating system.
✓HDR files are bit-for-bit perfect, preserving every pixel and sample for professional work.
✓HDR integrates seamlessly with all major photo editing tools and workflows.

Advantages of CGM

✓At its core, CGM relies on lossless encoding — a design choice that makes it perfect for Technical illustrations, engineering diagrams.
✓You won't run into compatibility issues with CGM — it's a universal standard across platforms.
✓File size management with CGM: larger files guaranteed to match the original exactly.
✓Every major application in the Technical illustrations, engineering diagrams space supports CGM natively.

Best Practices for HDR to CGM Conversion

→Before converting HDR to CGM, 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 CGM — you cannot recover detail lost during lossy compression
→Check the color profile: HDR images may use a wider gamut than CGM 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 HDR to CGM Conversion

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