DNG is a raw image format developed by Adobe. It is used for storing unprocessed data from digital cameras, providing the highest level of detail and flexibility for post-processing. DNG files are compatible with Adobe software like Photoshop and Lightroom, allowing for high-quality image editing and adjustments.
PNG is a lossless image format that supports transparency, making it ideal for logos, icons, and web graphics. Unlike JPEG, PNG doesn’t lose any image data during compression. It retains high-quality detail, especially in images with sharp edges, and is commonly used for design work where transparent backgrounds are required.
