What is AI?

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

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 AI vs ORF?

AI vs ORF: Key Differences

• •AI and ORF diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both AI and ORF use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •How transparency is handled: ORF supports transparency, so alpha information is preserved during conversion.
• •AI files are typically 500KB to 50MB depending on complexity while ORF files range 15-40MB per photo
• •Use case fit: AI targets vector illustration, logo design, print graphics and ORF targets olympus camera raw processing — your choice depends on which workflow stage you are serving.

Advantages of AI

• ✓AI uses lossless compression tailored for Vector illustration, logo design, print graphics.
• ✓AI is supported natively on virtually every device, browser, and operating system.
• ✓AI files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓AI integrates seamlessly with all major creative tools and workflows.

Common Use Cases for AI to ORF Conversion

• Social media posts and ads
• Digital photography and editing
• Graphic design projects
• E-commerce product images
• Email marketing campaigns
• Presentation graphics

Industry Applications

Best Practices for AI to ORF Conversion

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

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