PNG is a high-quality graphics format – generally higher in quality than JPEGs, which are compressed to save space. The PNG format uses lossless compression and is generally considered a replacement to the Graphics Interchange Format (GIF format).JPEG is better to use for processing and storing full-color realistic images, storing and transmitting digital graphic content and hosting and transmitting compressed images over the network. PNG is an ideal format for webmasters due to its optimal compression without quality loss, fast loading, transparency features, and clear image borders.
