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. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.
JPEG is a commonly used method of lossy compression for digital images, particularly those produced by digital photography.
