可谓是最适合网络的图片！PNG的优点是，清晰，无损压缩，压缩比率很高，可渐变透明，具备几乎所有GIF的优点；缺点是不如JPG的颜色丰富，同样的图片体积也比JPG略大。但是PNG应该在网站设计上被推广，它是公认的最适合网页使用的图片格式。Google就是一个很好的例子。Google所有站点几乎全部的图片资源都是PNG格式。8位的PNG完全可以替代掉GIF

PNG有着另一个优点，那就是逐次逼近显示(progressive display)：传输图像文件的同时，可以先把整个轮廓显示出来，然后逐步显示图像的细节，即先显示低分辨率显示图像，从模糊到清晰，然后逐步提高它的分辨率。这是一个很好的用户体验

各方面比较

大小比较：通常地，PNG ≈ JPG > GIF

透明性：PNG > GIF > JPG

色彩丰富程度：JPG > PNG >GIF

兼容程度：GIF ≈ JPG > PNG

体积大小，png可以比jp小很多，特别对于网络图片，因为颜色有限，560kb

>>32kb ...
