Conversion Quality Deep Dive
Digital Negative retains all original data. Converting to PEF Raw Photo adds no further quality degradation since it uses lossless compression. Xonvert selects parameters that maximize quality for the target format. For professional use, quality assurance is critical. Xonvert's Digital Negative to PEF Raw Photo pipeline has been tested against reference implementations to ensure output meets image industry standards. Real-world quality depends on three factors: source file quality, format capabilities, and encoder settings. Xonvert optimizes the third factor automatically, but starting with the best possible Digital Negative source always yields the best PEF Raw Photo output.
Converting between image formats is one of the most common file operations. When moving from Digital Negative to PEF Raw Photo, key considerations include color depth preservation, transparency support, and compression artifacts. Both formats preserve images losslessly, so this conversion is purely a container change with zero quality impact.
The DNG to PEF conversion applies format-appropriate algorithms to ensure maximum data fidelity. Supported by Lightroom, Photoshop, GIMP and darktable
