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 PEF?

Pentax Electronic Format (PEF) contains raw sensor data from Pentax digital SLR and mirrorless cameras.

When Should You Use AI vs PEF?

Use AI When...

If vector illustration, logo design, print graphics is your end goal, AI is the smart pick. Its exacting standards ensure your output matches your input at every stage.

Use PEF When...

Reach for PEF when your priority is pentax camera post-processing — its uncompromising quality ensures every detail is preserved.

AI vs PEF: Key Differences

  • •AI uses lossless compression while PEF 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: PEF lacks transparency support.
  • •File sizes: AI files typically range 500KB to 50MB depending on complexity and PEF files 15-45MB per photo.
  • •Use case fit: AI targets vector illustration, logo design, print graphics and PEF targets pentax camera post-processing — your choice depends on which workflow stage you are serving.

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.

Best Practices for AI to PEF Conversion

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

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