What is HEIC?

HEIC (High Efficiency Image Container) is a modern image format developed by the HEVC industry group. It uses advanced compression to achieve much smaller file sizes than JPEG.

What is PEF?

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

When Should You Use HEIC vs PEF?

Use HEIC When...

Reach for HEIC when your priority is ios photography, mobile devices — its efficient compression makes sharing fast and storage minimal.

Use PEF When...

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

HEIC vs PEF: Key Differences

  • •HEIC uses lossy compression while PEF uses lossless compression — this is the fundamental technical difference between the two formats.
  • •Moving from HEIC (lossless) to PEF (lossless) means the output file will be larger — but every bit of the original is preserved.
  • •How transparency is handled: PEF supports transparency, so alpha information is preserved during conversion.
  • •HEIC files are typically 50% smaller than equivalent JPEG while PEF files range 15-45MB per photo
  • •Use case fit: HEIC targets ios photography, mobile devices and PEF targets pentax camera post-processing — your choice depends on which workflow stage you are serving.

Advantages of HEIC

  • ✓At its core, HEIC relies on lossy encoding — a design choice that makes it perfect for iOS photography, mobile devices.
  • ✓You won't run into compatibility issues with HEIC — it's a universal standard across platforms.
  • ✓File size management with HEIC: aggressive compression with minimal visible quality loss.
  • ✓Every major application in the iOS photography, mobile devices space supports HEIC natively.

Advantages of PEF

  • ✓At its core, PEF relies on lossless encoding — a design choice that makes it perfect for Pentax camera post-processing.
  • ✓You won't run into compatibility issues with PEF — it's a universal standard across platforms.
  • ✓File size management with PEF: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Pentax camera post-processing space supports PEF natively.

Troubleshooting HEIC to PEF Conversion

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