What is PCD?

Kodak Photo CD (PCD) is a high-resolution image format for storing scanned photos on CD, supporting multiple resolutions from thumbnail to 3072x2048.

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 PCD vs AI?

PCD vs AI: Key Differences

• •PCD uses lossy compression while AI uses lossless compression — this is the fundamental technical difference between the two formats.
• •Moving from PCD (lossless) to AI (lossless) means the output file will be larger — but every bit of the original is preserved.
• •Transparency: Full vector transparency support
• •File sizes: PCD files typically range 4-6MB per image at base resolution and AI files 500KB to 50MB depending on complexity.
• •PCD is optimized for photo cd scanning, legacy photo archiving while AI is designed for vector illustration, logo design, print graphics — choose based on your specific workflow needs

Advantages of PCD

• ✓PCD uses lossy compression tailored for Photo CD scanning, legacy photo archiving.
• ✓PCD is supported natively on virtually every device, browser, and operating system.
• ✓PCD files are compact and quick to transfer, even over slow connections.
• ✓PCD integrates seamlessly with all major photo editing tools and workflows.

Advantages of AI

• ✓AI applies lossless compression specifically calibrated for Vector illustration, logo design, print graphics.
• ✓AI enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓AI guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find AI support built into virtually every tool that handles Vector illustration, logo design, print graphics — no plugins or converters needed.

Common Use Cases for PCD to AI Conversion

• Brochure and flyer design
• Newsletter graphics
• Video thumbnail creation
• Certificate and badge design
• Websites and online content
• Print materials and publications

Industry Applications

Best Practices for PCD to AI Conversion

• →Before converting PCD 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: PCD 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 PCD to AI Conversion

• !Converting PCD to AI gives blurry output → increase the quality setting before conversion
• !Colors look different in AI than PCD → 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 PCD turned white in AI → AI may not support transparency
