What is a PNG File
What is PNG digital Signage
Portable Network Graphics (PNG) is a bit map image format that employs lossless data compression. PNG was created to improve upon and replace GIF (Graphics Interchange Format) as an image-file format not requiring a patent license.
PNG supports palette-based (palettes of 24-bit RGB colors), grayscale and RGB images. PNG was designed for transferring images on the Internet, not professional graphics, and so does not support other color
spaces, such as CMYK.
PNG files nearly always use file-extension â€œPNGâ€ or â€œpngâ€ and are assigned MIME media type â€œimage/pngâ€ (approved October 14, 1996).
