What is png?

PNG stands for Portable Network Graphics. It is a raster graphics format that was created as an alternative to GIF. PNG files are used for storing images with high-quality graphics and support transparency. They are commonly used on the web because they can compress images without losing any quality.

PNG files can be both fully opaque or have transparent backgrounds, which makes them a popular choice for logos or graphics that need to be placed on various backgrounds. PNG files are also capable of containing metadata, which can include information about the image creator or copyright information.

One of the advantages of PNG files is that they can be used with both Mac and Windows operating systems. They also support a wide range of colors and are capable of displaying transparency effects. However, PNG files can also be larger than other image formats, such as JPEG, which can be a disadvantage for web optimization.
