Convert PEF to JPG

What Is the PEF Format?

PEF (Pentax Electronic File) is Pentax's proprietary RAW image format used by their DSLR cameras. PEF files store unprocessed sensor data with full 14-bit color depth, preserving the complete dynamic range and tonal information captured by the sensor. While Pentax cameras can also save in the universal DNG format, PEF remains the native option that many Pentax photographers prefer for its compatibility with Pentax-specific software and workflows.

Which Cameras Use PEF?

PEF files are produced by Pentax DSLR cameras spanning several generations. Popular models include the Pentax K-3 Mark III, K-3 Mark III Monochrome, K-1 Mark II, K-1 (full-frame), K-70, KF, KP, and the K-S2. The flagship K-1 Mark II features a 36-megapixel full-frame sensor with Pixel Shift Resolution, while the K-3 Mark III offers a 26-megapixel APS-C sensor with outstanding weather sealing, making Pentax cameras a favorite among landscape and outdoor photographers.
