What is GBR?

GIMP Brush (GBR) is the custom brush format for the GIMP image editor, allowing digital artists to create and share custom brush tips.

What is ARW?

Sony Alpha Raw (ARW) is Sony's proprietary raw image format containing unprocessed sensor data from Sony Alpha and Cyber-shot cameras.

When Should You Use GBR vs ARW?

GBR vs ARW: Key Differences

• •GBR uses lossless compression while ARW uses lossless compression — both take the same approach to file size management.
• •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Transparency: N/A
• •GBR files are typically Very small, typically under 100KB while ARW files range 20-40MB per photo
• •GBR is optimized for digital painting, gimp brush presets while ARW is designed for sony camera post-processing, professional editing — choose based on your specific workflow needs

Advantages of GBR

• ✓GBR uses lossless compression tailored for Digital painting, GIMP brush presets.
• ✓GBR is supported natively on virtually every device, browser, and operating system.
• ✓GBR files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓GBR integrates seamlessly with all major creative tools and workflows.

Advantages of ARW

• ✓ARW uses lossless compression tailored for Sony camera post-processing, professional editing.
• ✓ARW is supported natively on virtually every device, browser, and operating system.
• ✓ARW files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓ARW integrates seamlessly with all major creative tools and workflows.

Common Use Cases for GBR to ARW Conversion

• Websites and online content
• Print materials and publications
• Social media posts and ads
• Digital photography and editing
• Graphic design projects
• E-commerce product images

Industry Applications

Best Practices for GBR to ARW Conversion

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

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