What is a PEF file?
A .PEF file can belong to several different software programs. Most often, it is a Pentax Electronic File created by a Pentax digital camera. These are raw, uncompressed image files based on the .TIFF format. Photographers use these files to capture maximum sensor data for later editing.
Because .PEF files have multiple possible meanings, your file might also be a Portable Embosser Format file. The DAISY Consortium uses this XML-based format to store digital braille books. Additionally, some Pelco video security systems export surveillance footage as .PEF files.
How to open PEF files?
The correct software depends on the file type. You can open Pentax camera images using Pentax Digital Camera Utility or mainstream photo editors. For Braille documents, use the Daisy Pipeline Editor. For surveillance video, you need the XProtect Smart Client.
If you are unsure what type of .PEF file you have, viewer.online/pef analyzes .PEF files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
File Conversion
You can often convert camera raw images into standard formats for easy sharing. We recommend using convert.guru to convert .PEF images into .JPG or .PNG formats.
Summary
Installing multiple specialized applications is time-consuming. viewer.online/pef directly opens and previews .PEF files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
