Not a very new technology, 'Smush it' is based on the concept of reducing unnecessary pixel space from your images, so that they can load faster and look better.
Smush.it uses optimization techniques specific to image format to remove unnecessary bytes from image files. It is a "lossless" tool, which means it optimizes the images without changing their look or visual quality. Now lossless, with regard to the word is very attractive, but certain limitations come into picture when you compress or Decompress a file. Compressing a file in layman's terms is to reduce the amount of size it takes to store the image. For Lossless image scalling, One must keep in mind, that there is always some loss, when you scale up an image. So for Photographic compression, softwares are able to compress an image more, when losses are allowed, but, When the user does not allow any losses, then there is a limit to the amount of compression or Decompression.
After Smush.it runs on a web page it reports how many bytes would be saved by optimizing the page's images and provides a downloadable zip file with the minimized image files.
The technique is very simple,
1.> Upload the file
2.> Or provide a link for your photo
3.> Then click on the smush button
4.> Image is smushed
5.> Finally you can always Download the smushed file
6.> And you're done.
