Compression rates of 100:1 can be achieved, although the loss is noticeable at that level. JPEG involves a lossy compression mechanism using discrete cosine transform (DCT). Alternatively, drag and drop individual images or a folder of images directly onto the Adobe DNG Converter icon. Launch the DNG Converter by double-clicking its icon. Select the location where you want to save the converted DNG files. Select the folder of images you'd like to convert to DNG. This action automatically launches the converter.

It supports the various forms of metadata - Exif metadata, XMP metadata, IPTC metadata. The format conforms to TIFF specifications and is structured according to TIFF. Adobe developed the Digital Negative format (DNG) as an open lossless RAW image file because they wanted to ensure that the DNG format would satisfy the following objectives (that they felt the RAW file format would not): digital image preservation (sometimes known as archiving), easy and/or comprehensive exploitation by software developers, in-camera use by camera manufacturers and multi-vendor interoperability.Ī DNG file contains a JPEG preview, with metadata and data for the one main image.
