An image format that uses advanced JPEG 2000 waveform compression. Supports color depths of 8, 24, and 32 bits per pixel. Also supports grayscale, RGB, YCbCr, XYZ, and Lab color space. Compatible with most available programs, easy to open and convert.
The PNG format was created to both enhance and replace the GIF format with a graphic format that does not require a license to use. Unlike GIF, PNG has alpha channel support and the ability to store an unlimited number of colors. PNG compresses data without losses, making it very useful for storing intermediate versions of image processing. Portable Network Graphics is a convenient format to place the file in an electronic document if it does not need to be printed later. PNG is completely unsuitable for printing, hence you have to convert it to print.
