PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB images (with or without alpha channel). However, PNG itself does not support animation at all. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF) and is the most used lossless image compression format on the Internet. Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. It was initially developed for the Xfig drawing program, but today it's used in other drawing editors. In addition, it can contain a set of colors, images, and sketches. They include text objects, splines, forms, arcs, lines, and arrows. This is a file used for creating line plots in the form of vector images.
