A PNG (Portable Network Graphics) file is a raster graphic format that supports lossless data compression. It was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF).
PNG files are commonly used for storing web graphics, digital photographs, and images with transparent backgrounds. They are favored for their ability to display images with a high level of detail and clarity, especially when compression of the image data does not degrade visual quality.
Unlike JPEG, PNG supports transparency, making it ideal for graphics and images with varying degrees of opacity.
