PEF is Pentax's RAW format, used across their DSLR camera lineup to store unprocessed sensor data with maximum editing flexibility for exposure, white balance, and color correction. When archiving or further editing matters more than minimizing file size, PNG is the better target than JPG, since it's lossless and won't introduce any additional compression artifacts once the file has been demosaiced.
Converting PEF to PNG is the practical choice for preserving maximum image quality when revisiting photos captured on a Pentax camera, particularly for shots you plan to bring into further editing later.
