What is CPT?

Corel PHOTO-PAINT (CPT) is the native project format for Corel PHOTO-PAINT, preserving layers, masks, and editing history.

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 CPT vs RAF?

CPT vs RAF: Key Differences

• •CPT uses lossless compression while RAF uses lossless compression — both take the same approach to file size management.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Transparency: N/A
• •File sizes: CPT files typically range Large due to layer data and RAF files 20-50MB per photo.
• •Use case fit: CPT targets corel image editing, photo manipulation and RAF targets fujifilm photography, film simulation processing — your choice depends on which workflow stage you are serving.

Advantages of CPT

• ✓CPT applies lossless compression specifically calibrated for Corel image editing, photo manipulation.
• ✓CPT enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓CPT guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find CPT support built into virtually every tool that handles Corel image editing, photo manipulation — no plugins or converters needed.

Advantages of RAF

• ✓RAF uses lossless compression tailored for Fujifilm photography, film simulation processing.
• ✓RAF is supported natively on virtually every device, browser, and operating system.
• ✓RAF files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓RAF integrates seamlessly with all major photo editing tools and workflows.

Common Use Cases for CPT to RAF Conversion

• Certificate and badge design
• Websites and online content
• Print materials and publications
• Social media posts and ads
• Digital photography and editing
• Graphic design projects

Industry Applications

Best Practices for CPT to RAF Conversion

• →When converting CPT 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 CPT 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 CPT 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 CPT 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
