How to Convert Images to PNG Free

PNG (Portable Network Graphics) supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and RGB images (with or without alpha channel). PNG was designed for transferring images on the Internet, not for print graphics, and therefore does not support non-RGB color spaces such as CMYK.
