Image Optimizer for Google Lighthouse


Upload a JSON file generated by Google’s Lighthouse website auditing tool and this plugin will compress and replace all flagged images using the API.


  1. Run Lighthouse on the page of your website you want to optimize images. The easiest way to do this is using Chrome Developer Tools, but you may also utilize the Lighthouse Chrome Extension or run an audit on the command line using Node.
  2. Download the report as a JSON file.
  3. In the WordPress Dashboard, navigate to Media -> Lighthouse Image Optimizer, upload the JSON file and click “Optimize Images.”


  • Plugin page upon landing.
  • After successful optimization.
