A DNG Converter is a tool developed by Adobe that converts camera-specific raw files into a more universal DNG (Digital Negative) raw file format. DNG is Adobe's proprietary image standard for raw and uncompressed images.Using the DNG Converter allows photographers to store their raw images in a single, standardized format. This helps with both archiving and future compatibility, as the DNG format is designed to be open and accessible, making it more likely to be supported in the long term by various software. It's also useful in instances where a camera's raw file format isn't immediately supported by ACR or Lightroom; the files can be converted to DNG and then edited.
