Pentax Electronic File (PEF) is a raw image file format produced by Pentax digital cameras, which stores an unedited and uncompressed image. The benefit of working with a raw image is that it provides high-quality images, the ability to recover information, ease in making corrections, and many other advantages and benefits.

Many other programs can open this file type successfully. For both Microsoft Windows and macOS, Adobe Photoshop, Adobe Photoshop Lightroom works well for opening and converting PEF. On Linux/Unix, darktable is open source, cross-platform, and free. PEF is usually converted to Adobe Digital Negative Raw Image (DNG), Tagged Image File Format (PEF to TIFF), JPG (PEF to JPEG), or Portable Network Graphics (PEF to PNG) file formats.
