Bandwidth Hero saves data by compressing all images on the page via data compression service which reduces image size by about 50%-75%. Compression service downloads original image, converts it to low-res JPEG 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. After installing this extension you will need to setup data compression service to run on Heroku or our own Node.js server. The extension is open-sourced, you can check the code on GitHub - https://github.com/ayastreb/bandwidth-hero/ --- By installing this addon and using it with public data compression service (https://compressor.bandwidth-hero.com) you agree with our Terms and Conditions of Use.
