PNG

Portable Network Graphic

A raster graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF) and is the most widely used lossless image compression format on the Internet. PNG supports features such as alpha transparency (for soft transparency), gamma correction, and two-dimensional interlacing, making it a versatile choice for web graphics. It is particularly useful for images with large areas of uniform color and for storing images that need to be edited repeatedly, as the lossless compression ensures that image quality is not degraded over time with multiple saves.
