Compressing Image with Image Opertimazer

Compressing plain text is easy by Zipping the files, however, images are said to be compressed by default, so often we are ignoring optimizing it.

I just found one awesome tool to optimize the website images without sacrificing much quality:Image Opertimazer

Here is the default Image, original size is 52KB:

After optimization, the size is 33KB, about 20% saving:

And you may heard of WebP created by Google, it is said that "WebP images were 39.8% smaller than jpeg images of similar quality", give it a try! Update: another awesome service to do Image compression, called JPEGmini : http://www.jpegmini.com/main/home
