Lossless Image Optimization for JPG, GIF and PNG in Wordpress

Question

Within my site I have images only which takes a lot of time for page load. I've developed site using WordPress. I've used WP.Smush It plugin for optimization but still not getting proper output. Is there any free tool or script to do such task?

I don't want to lose quality of images. I've .jpg, .png and .gif images format.
