Convert DNG to PNG — Free Online Converter

PNG provides lossless compression that preserves every pixel of the demosaiced DNG sensor data without compression artifacts. Converting DNG files to PNG produces web-friendly, losslessly compressed images suitable for graphic design, compositing, technical documentation, and workflows where JPEG's lossy compression is unacceptable.

DNG's embedded calibration profiles (ColorMatrix, ForwardMatrix, baseline tone curve) ensure the most accurate possible color interpretation of the original sensor data, regardless of which camera captured the image. The PNG output faithfully preserves this color-correct rendering in a widely compatible lossless format.

PNG excels where image integrity is paramount. Graphic designers compositing archived photographs with other elements prefer PNG because it preserves sharp edges without JPEG artifacts. Product photographers exporting from DNG archives for web catalogs with transparent backgrounds require PNG since JPEG lacks alpha channel support.

For technical and scientific photography archived in DNG format, PNG provides verifiable lossless output. The pixel values exactly match the demosaiced rendering with no compression-induced changes, important in fields where lossy compression may violate regulations or institutional standards.
