What is ORF?

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

What is AI?

Adobe Illustrator Artwork (AI) is the native vector graphics format for Adobe Illustrator, used for logos, illustrations, and print designs.

When Should You Use ORF vs AI?

ORF vs AI: Key Differences

• •ORF uses lossless compression while AI 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.
• •Alpha channel support: AI handles transparency.
• •ORF files are typically 15-40MB per photo while AI files range 500KB to 50MB depending on complexity
• •Use case fit: ORF targets olympus camera raw processing and AI targets vector illustration, logo design, print graphics — your choice depends on which workflow stage you are serving.

Advantages of ORF

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

Common Use Cases for ORF to AI 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 ORF to AI Conversion

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

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