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 ...
