We also realised that tackling web performance takes a lot of effort..so have been building different tools which can automate front end optimization techniques. Our recent tool (https://dexecure.com) tackles image optimization by generating different formats (WebP, JPEG XR), different sizes of images and compressed to different qualities depending on the device and browser the user is using. All of the images are served with a fast HTTP/2 connection.
We have seen people integrate with it in under 5 minutes and cut down their page size by 40%!
