Free Online Pentax PEF to JPG Converter

Convert Pentax PEF (Pentax Electronic Format) RAW camera files to standard JPG (JPEG) images online. While Pentax (Ricoh Imaging) cameras allow shooters to choose between Adobe DNG and Pentax's native TIFF-based `.pef` container, PEF remains widely used on Pentax K-series DSLRs (such as the K-1, K-1 Mark II, K-3 Mark III, KP, K-70, and K-5) as well as Pentax 645D and 645Z medium-format bodies. Converting PEF to JPG develops the 12-bit or 14-bit sensor data into a compact image that works on every browser, phone, and website.

Why Convert PEF to JPG?

  • Direct viewing & sharing: Web browsers, messaging apps, and print labs do not accept `.pef` files directly; JPEG is supported everywhere.
  • Compact file size: Unprocessed Pentax RAW files typically range from 25 MB to 75 MB, whereas converted JPEGs are a fraction of that size while preserving high visual fidelity.
  • Automatic orientation: Reads the EXIF orientation tag recorded by Pentax Shake Reduction (SR) sensors so portrait images display upright.

How to Convert PEF to JPG

  1. Upload your PEF file — Select the .pef RAW photo from your device or paste a direct URL.
  2. Click "Convert to JPG!" — The Pentax RAW image is demosaiced and rotated automatically.
  3. Download or edit — Save the converted JPEG, or refine it with our image resizer, crop tool, or JPG optimizer.

If your Pentax camera was set to shoot DNG instead of PEF, you can also use our DNG to JPG or DNG to PNG converters.
