File Description

Portable Network Graphics .PNG is an 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.


The .PNG format is one of the few image formats with complete support for alpha channels (transparency). PNG supports palette-based, greyscale, or RGB images. PNG does not support CMYK color spaces.
