Turn off served by Google feature in Chrome
When will a user see these transcoded pages?
  
  Users will see these pages only if Google has detected that they are
  on a slow network connection in a country in which we enable
  transcoding.

This can be experienced in countries like Indonesia, India, etc. where the internet speed is considerably slow. Googlebot does this based on the network speed and then it "transcodes" the page with any images. But there is no way to turn this off in the Browser Settings. Only way a website can do this is by using the Cache-Control: no-transform header in the HTTP request.


  Opting out of transcoding If you do not want your pages to be transcoded, set the HTTP header "Cache-Control: no-transform" in your
  page response. If Googlebot sees this header, your page will not be
  transcoded.
  
  Please note that pages that opt-out of being transcoded will be
  labeled in search results to indicate to users that they may take
  longer to load and may use more data.


Will my pages be transcoded for users on faster networks?


  Pages will not be transcoded if the user is on a fast network.


So if you are on a faster network you won't experience this.
