PEF is Pentax's RAW format, used across their DSLR camera lineup to store unprocessed sensor data with full editing flexibility for exposure, white balance, and color correction. Like other camera RAW formats, PEF files require demosaicing before they're viewable, and since they aren't supported by browsers, photo viewers, or social platforms, converting to JPG is the practical way to view or share them.
Converting PEF to JPG performs that demosaicing and compresses the result into a small, universally compatible file, which is the standard step once a Pentax shoot has been edited and is ready to share, upload, or print.
