Pentax Electronic File (.pef)

The PEF (Pentax Electronic File) is a raw image format used by Pentax digital cameras, storing unprocessed data directly from the camera's sensor. This format retains all captured information, offering greater flexibility for post-processing and high-quality image editing. PEF files are similar to other raw formats like CR2 and NEF and are typically edited using specialized software such as Adobe Photoshop or Pentax's Digital Camera Utility.

Progressive JPEG (.pjpeg)

The PJPEG (Progressive JPEG) is a file extension for images that enhances the standard JPEG format by displaying images in successive waves of increasing detail, improving the user experience during slow network conditions. The JPEG stands for "Joint Photographic Experts Group", the organization that developed the standard in 1992. PJPEG is particularly useful for web applications, as it allows images to appear more quickly and progressively refine in quality, rather than loading from top to bottom like baseline JPEGs.
