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 IIQ?

Phase One IIQ is a professional medium-format raw format used by Phase One digital backs, delivering exceptional image quality for commercial photography.

When Should You Use AI vs IIQ?

AI vs IIQ: Key Differences

• •AI and IIQ diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both AI and IIQ use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Transparency: N/A
• •AI files are typically 500KB to 50MB depending on complexity while IIQ files range 50-150MB per image from medium-format backs
• •AI is optimized for vector illustration, logo design, print graphics while IIQ is designed for professional studio photography, digital back capture — choose based on your specific workflow needs

Advantages of AI

• ✓The lossless nature of AI means file sizes stay reasonable while handling Vector illustration, logo design, print graphics efficiently.
• ✓From mobile devices to enterprise servers, AI is recognized and supported everywhere.
• ✓The trade-off for AI's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓AI is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of IIQ

• ✓IIQ uses lossless compression tailored for Professional studio photography, digital back capture.
• ✓IIQ is supported natively on virtually every device, browser, and operating system.
• ✓IIQ files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓IIQ integrates seamlessly with all major photo editing tools and workflows.

Common Use Cases for AI to IIQ Conversion

• Graphic design projects
• E-commerce product images
• Email marketing campaigns
• Presentation graphics
• Blog and article illustrations
• Mobile app UI assets

Industry Applications

Best Practices for AI to IIQ Conversion

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

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