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.
Ricoh Imaging Americas Corporation provides PENTAX PHOTO Laboratory software, which is the default for opening PEF. Another common program for viewing PEF is PENTAX PHOTO Browser. A non-Pentax program for opening PEF is Adobe Photoshop Lightroom.
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.

The Portable Document Format (PDF) is a universal file format that comprises characteristics of both text documents and graphic images which makes it one of the most commonly used file types today. The reason PDF is so widely popular is that it can preserve original document formatting. PDF files always look identical on any device or operating system.
Most people head right to Adobe Acrobat Reader when they need to open a PDF. Adobe created the PDF standard and its program is certainly the most popular free PDF reader out there. It's completely fine to use, but I find it to be a somewhat bloated program with lots of features that you may never need or want to use.
Most web browsers, like both Chrome and Firefox, can open PDFs themselves. You may or may not need an add-on or extension to do it, but it's pretty handy to have one open automatically when you click a PDF link online. I highly recommend SumatraPDF or MuPDF if you're after something a bit more. Both are free.
