PNG

PNG (Portable Network Graphics) is an image format introduced in 1995 for displaying high-quality images. PNG was developed as an evolution of the GIF format. It was initially called PING, a name coined by Oliver Fromme, and was later shortened to PNG. The advantages of PNG include support for image transparency, brightness adjustment, and lossless compression, which means that no data is lost during the compression process.

Size of PNG can be compress by using compress PNG tools to have smallest size from original size, does not alter the colors of the original image.
