PEF to EXR Converter

Convert PEF files to EXR. Batch, free and without uploading.

This tool converts PEF files to EXR. PEF is the RAW format of Pentax cameras. It keeps unprocessed sensor data; conversion uses the camera’s white balance and colour settings.

HDR image (OpenEXR). EXR is lossless, so nothing is lost from the image during conversion. RAW files are large, so each photo may take a few seconds.

Conversion happens inside your browser; your files are never sent to a server.

2. Optionally set a maximum width and height.
3. Press "Convert" and download the EXR files one by one or as a ZIP.
