PNG (Portable Network Graphic)

Portable Network Graphics (PNG) is a bitmapped image format that employs lossless data compression. PNG was created to improve upon and replace the GIF format, as an image-file format not requiring a patent license. PNG is pronounced /'pɪŋ/ ping).[1] The PNG initialism is optionally recursive, unofficially standing for “PNG's Not GIF”.[2]

PNG supports palette-based (palettes of 24-bit RGB colors) or greyscale or RGB images. PNG was designed for transferring images on the Internet, not professional graphics so it does not support other color spaces (such as CMYK).
PNG files nearly always use file-extension "PNG" or "png" and are assigned MIME media type "image/png" (approved October 14, 1996).
DocFamily supports PNG as an image format used in documents as well as an output format for documents.
