What is CGM?

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

What is RAF?

Fujifilm Raw Format (RAF) contains raw sensor data from Fujifilm X-Series and GFX cameras with unique X-Trans sensor processing.

When Should You Use CGM vs RAF?

CGM vs RAF: Key Differences

• •CGM uses lossless compression while RAF uses lossless compression — both take the same approach to file size management.
• •Since both CGM and RAF use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: N/A
• •CGM files are typically Compact for vector drawings while RAF files range 20-50MB per photo
• •CGM is optimized for technical illustrations, engineering diagrams while RAF is designed for fujifilm photography, film simulation processing — choose based on your specific workflow needs

Advantages of CGM

• ✓CGM compresses data using lossless methods, keeping file sizes manageable for Technical illustrations, engineering diagrams.
• ✓Industry-wide support means CGM files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes CGM the gold standard for archival and master copies.
• ✓From professional software to open-source alternatives, CGM works out of the box.

Advantages of RAF

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

Common Use Cases for CGM to RAF Conversion

• Newsletter graphics
• Video thumbnail creation
• Certificate and badge design
• Websites and online content
• Print materials and publications
• Social media posts and ads

Industry Applications

Best Practices for CGM to RAF Conversion

• →When converting CGM to RAF, check whether RAF supports transparency — if not, your transparent areas will be filled with a solid color
• →Use RAF for maximum quality archival and CGM for lossless workflows
• →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
• →Maintain original aspect ratio to avoid distortion during conversion
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting CGM to RAF Conversion

• !RAF shows visible compression artifacts → lower the compression level or switch to a lossless variant
• !The converted RAF image looks washed out → the source CGM likely uses a wider color space than RAF supports
• !RAF file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
• !Text in the converted RAF looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
