Users should also select an output folder under 'Select location to save converted images'. Usage of the program is not difficult and involves selecting a folder where image files to be converted are located. It should be noted that 'DNG' actually means 'Digital Negative Converter' where 'Digital Negative' is Adobe's terminology for RAW image. Unlike Lightroom, DNG Converter is completely free. The technology inside of the Adobe DNG Converter is actually the same that is available from the well-known image editing program called Adobe Lightroom. It's not just professional or amateur-level SLR and mirrorless cameras that are supported by this conversion software either! You can convert RAW images created with your phone's camera to JPG or other formats more suitable for the web and sharing. It goes without saying that Adobe DNG Converter supports RAW images created by Canon, Nikon, Olympus and Sony but also supports those created by RAW shooting on Samsung, Panasonic, Sigma, Ricoh and Leica cameras. With Adobe DNG Converter, you have a freeware tool directly from Adobe which supports around 400 different types of image formats from digital cameras, from the low-end of the spectrum to high-end equipment. There are a lot of different camera brands around and even more types of RAW image formats which cannot be universally opened or edited.
