How do I convert a PEF file to EXR?

Upload your Pentax PEF file, choose EXR as the output format, and optionally select bit-depth (16-bit half float or 32-bit float). Click Convert, and the tool will demosaic the raw sensor data and encode it using OpenEXR with your chosen compression (e.g., ZIP or PIZ).

Why should I convert PEF to EXR?

PEF is a raw format specific to Pentax cameras, storing unprocessed sensor data. EXR (OpenEXR) is a high-dynamic-range format used in VFX and compositing, with floating-point channels and layer support. Converting to EXR allows you to retain full dynamic range and work with 16/32-bit float precision in tools like Nuke, After Effects, or Photoshop.

What happens to the raw data and metadata during PEF to EXR conversion?

The converter demosaics PEF's Bayer sensor data into an RGB image, outputting it as a scene-referred linear 16-bit half-float EXR by default. This preserves the original dynamic range and allows floating-point precision for highlights and shadows. EXIF metadata (e.g., lens, exposure) is not embedded in the EXR container; you can add custom metadata attributes if needed. The original raw mosaic and proprietary corrections are not retainable in EXR output.
