What is SRW?

Samsung Raw (SRW) contains raw sensor data from Samsung NX series cameras.

What is CPT?

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

When Should You Use SRW vs CPT?

SRW vs CPT: Key Differences

• •The core technical difference: SRW relies on lossless compression whereas CPT uses lossless compression.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Alpha channel support: CPT handles transparency.
• •File sizes: SRW files typically range 15-40MB per photo and CPT files Large due to layer data.
• •SRW is optimized for samsung camera raw post-processing while CPT is designed for corel image editing, photo manipulation — choose based on your specific workflow needs

Advantages of SRW

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

Advantages of CPT

• ✓CPT uses lossless compression tailored for Corel image editing, photo manipulation.
• ✓CPT is supported natively on virtually every device, browser, and operating system.
• ✓CPT files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓CPT integrates seamlessly with all major photo editing tools and workflows.

Common Use Cases for SRW to CPT Conversion

• Video thumbnail creation
• Certificate and badge design
• Websites and online content
• Print materials and publications
• Social media posts and ads
• Digital photography and editing

Industry Applications

Best Practices for SRW to CPT Conversion

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

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