PEF to JXR: what carries over and what does not

PEF files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to JXR bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after.

"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

PEF to JXR Conversion: FAQ

What are PEF files?

The PEF image format is used for creating RAW images with Pentax cameras. Shooting in RAW mode allows the camera to capture everything its sensors can register, thus preserving a huge amount of details — as opposed to JPEG or other compressed formats, which have predefined settings and are processed automatically. With PEF images, photographers have more freedom to change the image during digital post-processing without affecting its quality. With the help of specialized software, aspects such as lights, exposure and shadows can be customized in the image, highlighting or hiding particular details.

What are JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression. Its 48-bit RGB color range allows for accuracy in rendering images and better graphic representation. Additionally, JXRs can include an alpha channel which facilitates the editing of transparent layers.
