How to Save Bandwidth Using Bandwidth Hero

Posted on

Hi friends, this time I will share how to save Bandwidth for PC users who use chrome or firefox, Bandwidth Hero is an open-source browser extension that reduces the amount of data consumed when you browse web pages by compressing all the images on the page. It uses a data compression service to convert the image to a low-resolution WebP or JPEG image.


  1. When active, Bandwidth Hero prevents all image loading requests
  2. Then Bandwidth Hero sends each image URL to a data compression service
  3. Compression service download original image
  4. Once the image is downloaded, it is then converted to a low-resolution WebP/JPEG image.
  5. The compression service returns the processed image to the browser for download, for example, the original 100 KB image will later become 65-70KB, if there are 10 images on 1 page, it means you have saved 300KB

The tutorial for this is below:
