What is a PEF file?
PEF (Pentax Electronic Format) is the proprietary RAW image format used by Pentax DSLR cameras. PEF files are produced by cameras including the Pentax K-3 III, K-3 III Monochrome, K-1 Mark II, KP, K-70, and the medium format 645Z. Pentax cameras are renowned for their weather-sealed, rugged bodies and Shake Reduction (SR) in-body image stabilization. PEF files store unprocessed 14-bit sensor data, preserving the full dynamic range and color information for maximum post-processing flexibility. File sizes typically range from 20-40 MB for APS-C and 40-80 MB for medium format.
PEF vs JPG — What's the difference?
PEF files store unprocessed 14-bit sensor data with 12-14 stops of dynamic range, while JPG compresses images to 8 bits per channel with lossy compression. PEF preserves the complete tonal range captured by Pentax's sensors, allowing extensive adjustments to exposure, white balance, and color rendering. JPG files are much smaller and universally compatible, but permanently discard the editing flexibility that PEF provides.
When should you convert PEF to JPG?
Convert PEF to JPG when you need to share your Pentax photos online, via email, or through messaging apps. JPG is required for web publishing, social media uploads, and most printing services. Pentax shooters often accumulate large libraries of PEF files — converting finished edits to JPG creates lightweight, universally compatible copies suitable for any sharing or display purpose.

Will I lose quality converting PEF to JPG?
PEF files contain more data than JPG can represent, so some dynamic range is reduced. However, our converter produces high-quality JPGs at 85% quality that look excellent for sharing, printing, and web use.
Which Pentax cameras use PEF?
All Pentax DSLRs support PEF, including the K-3 III, K-3 III Monochrome, K-1 Mark II, KP, K-70, K-S2, and the medium format 645Z. Some Pentax cameras also offer DNG as an alternative RAW format.
Should I use PEF or DNG in my Pentax camera?
Many Pentax cameras let you choose between PEF and DNG. PEF is Pentax's native format with full compatibility in Pentax-specific software. DNG is Adobe's open standard with broader software support. Both are fully supported by this converter.
