Bandwidth Hero (Refactored)

RepositoryLicense MITPRs WelcomeVersionIssuesProject CI

Bandwidth Hero is an open-source browser extension which reduces the amount of data consumed when you browse web pages by compressing all images on the page. It uses data compression service to convert images to low-resolution WebP or JPEG images.

How It Works?

Workflow

  1. When active, Bandwidth Hero intercepts all images loading requests
  2. It sends each image URL to the data compression service
  3. Compression service downloads the original image
  4. Once image is downloaded it is then converted to low-resolution WebP/JPEG image.
  5. Compression service returns processed image to the browser

Privacy Consideration

After installing the extension you need to setup data compression service.

Please refer to data compression service docs for detailed instructions on how to run your own service.

Once you have your own instance running, click "Configure data compression service" button under "Compression settings" in the extension popup.
