What is a PEF file?
PEF (Pentax Electronic File) is a RAW image format used by Pentax digital cameras. It contains unprocessed data directly from the camera's image sensor, offering higher quality and editing flexibility than JPEG.
PEF files are typically large and require specialized software to view or edit. Our Online PEF Viewer allows you to preview these RAW photos without installing heavy software like Lightroom.

Frequently Asked Questions

Why does the PEF file look flat?
