RAW images in no matter which format they are not ideal for viewing on standard image viewers. Professional photographers can get past this issue as they have access to high-end photo editors, like Lightroom or Photoshop. However, for beginners, it isn‘t an easy ride. Under such circumstances, you can convert your RAW files in PEF to JPG. We will explore how to batch convert PEF to JPEG in this thorough guide.

Part 1. How to open a PEF file?

The Pentax Electronic Format or PEF is a RAW image format used in the digital cameras made by Pentax. This means it represents what your camera sees and feels without any color adjustments or details lost due to compression. Moreover, standard bitmap graphics editors will produce an error when editing this type of photo like other RAW formats such as JPG files.

However, with applications like AfterShot Pro though, you can edit PEFs much quickly. Other programs that can read the PEF files include Adobe Photoshop, Windows Live Photo Gallery, and UFRaw.
