Portable Network Graphic files

The PNG file extension is commonly used for images in Portable Network Graphics file format.

PNG is a bitmap graphics format similar to GIF, that uses image compression mainly for web purposes. PNG is a lossless format with 16.7 million colors, index color, grayscale, true color, transparency and also is streamable, which makes it superior to GIF.

The format was approved as a standard by the WWW consortium to replace GIF, because GIF is using a patented data compression algorithm called LZW. In contrast, PNG is completely patent- and license-free.

Originally only Netscape Navigator and Microsoft Internet Explorer supported PNG file format, but today every web browser can read the format correctly.
