Portable Network Graphics (PNG) is a popular image file format used for storing digital images. It was developed as a replacement for the older Graphics Interchange Format (GIF) and supports lossless compression, meaning that images retain their quality even after being compressed. PNG files can handle a wide range of colors and are often used for web graphics, logos, and images requiring transparency. One of the key features of PNG is its ability to support transparency, allowing images to blend seamlessly with different backgrounds. This makes it a preferred choice for designers and web developers. Additionally, PNG files can store metadata, which can include information about the image, such as its creation date and author.
