Kraken.io Image Optimizer vs. Filestack

The majority of today's static web traffic is made up of images. While many tools exist for preparing images for the web, such as Photoshop's Save For Web tool and a plethora of other existing resizing and compression techniques, most tools have major shortcomings - such as being restricted to just one format (such as GIF, PNG or JPEG). Many tools will simply force an image down to a particular quality level such as a quality setting of 70 for JPEG images, regardless of what the results look like.
