Saves data by compressing images on the page.
Bandwidth Hero saves data by compressing all images on the page via compression proxy server, it reduces image size about 50%.
Proxy server downloads original image, converts it to greyscale WebP image and returns it to the browser.
Unlike Google's Data Saver, Bandwidth Hero works for both secure and unsecure URLs.
It is very useful when you use limited data, such as 3G or LTE.
Compression proxy server does not save images anywhere, it processes them on the fly.
You can use default proxy server or run your own instance for free using services like Heroku or Webtask.io.
The extension is open-sourced, you can check the code on GitHub - https://github.com/ayastreb/bandwidth-hero/
