Do you need to convert PEF to JPEG to browse the image? What should be the best Pentax RAW viewer to view the photos? Just learn more details about the answer from the article now.

How to View Pentax RAW Images

Part 1: Should You Convert PEF file to JPEG?

PEF is a RAW image format of a Pentax camera. Compared to the JPEG files, the PEF photos are better for adjustment or editing. When you need to save the files for further editing or back up all the details, PEF is a suitable RAW file you have to choose.

If you need to view the photos on your Android phone directly or even share online streaming sites, JPEG is a compressed image format compatible with most devices. It can produce a smaller file size. If you want to share your image files to social media or view PEF files on mobile devices, you can convert PEF files to JPG.

If you need to save the best quality and everything for the image, both PEF and DNG are the file formats you should choose. To further edit the photos, share them on social media sites, or even reduce storage space, the JPEG is a file format you can choose.

Part 2: What Is a PEF File Format?

PEF, standing for Pentax Electronic Format, is a raw image file containing minimally processed data from the image sensor of a Pentax digital camera. It stores all data and information captured by your camera sensor so that you can adjust the color, contrast, brightness, and more simply. To view a PEF file, you need an associated program.

To fine-tune the tone and colors for the PEF files, you have to choose professional software, such as Digital Camera Utility 5 from Pentax or even Lightroom. Just like analog negatives, raw images cannot view unless they develop first.

What are the differences between PEF and DNG? Just as mentioned above, Pentax has two different RAW file formats, here are the key distinctions between PEF and DNG. DNG files can be read and processed by a wide range of software applications, whereas PEF files may require specific Pentax software or converters. PEF files typically use Pentax's proprietary compression algorithm, which offers lossless compression. On the other hand, DNG files can be stored uncompressed or compressed using various compression methods such as lossless or lossy compression.
