What is DRW?

Generic Drawing (DRW) is a simple vector illustration format used by various drawing applications for basic line art.

What is ORF?

Olympus Raw Format (ORF) contains raw sensor data from Olympus OM-D, PEN, and other Olympus digital cameras.

When Should You Use DRW vs ORF?

DRW vs ORF: Key Differences

• •The core technical difference: DRW relies on lossless compression whereas ORF uses lossless compression.
• •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
• •DRW files are typically Small for simple drawings while ORF files range 15-40MB per photo
• •DRW is optimized for vector drawings, simple illustrations while ORF is designed for olympus camera raw processing — choose based on your specific workflow needs

Advantages of DRW

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

Advantages of ORF

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

Common Use Cases for DRW to ORF Conversion

Industry Applications

Best Practices for DRW to ORF Conversion

• →When converting DRW to ORF, check whether ORF supports transparency — if not, your transparent areas will be filled with a solid color
• →Use ORF for maximum quality archival and DRW 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 DRW to ORF Conversion

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