What is a .PEF file?
PEF is Pentax’s camera RAW format (Pentax Electronic Format). Opened in Adobe Lightroom or Pentax software.
- Did you know
- PEF is the raw format for Pentax DSLRs.
- PEF stands for Pentax Electronic Format and, like most raw formats, is built on a TIFF-based container holding the sensor’s mosaic data plus metadata.
- Pentax bodies let you choose between saving raw as PEF or as Adobe’s open DNG directly in-camera, a flexibility few rival makers offered.
- Ricoh, which absorbed Pentax’s camera business, supplies a free PEF codec so Windows can show the proprietary files as ordinary thumbnails.
- Because PEF is proprietary, archivists often recommend converting to DNG so the images stay readable long after Pentax software is gone.
- What Analyser shows you
- Open camera RAW files from Sony (ARW), Canon (CR2, CR3, CRW), Nikon (NEF, NRW), Fujifilm X-Trans (RAF), Sigma Foveon (X3F), Olympus (ORF), Panasonic (RW2), Pentax (PEF), Adobe DNG and many more. Reads full EXIF and lens data, the true sensor resolution, GPS and histograms, recovers the Sony and Nikon shutter actuation count, and develops the RAW - decoding the sensor to a full-resolution image, or extracting the embedded preview when a true demosaic is not available.
- Open a .PEF file
- Drag a .PEF file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
