Image Optimizer for Google Lighthouse is a WordPress plugin designed to streamline image optimization for websites. This free tool utilizes the reSmush.it API to automatically compress and replace images flagged during a Google Lighthouse audit. Users can easily enhance their site's performance by addressing image-related issues identified in their Lighthouse reports.

To use the plugin, website owners first run a Lighthouse audit on their desired page, which can be done through Chrome Developer Tools or the Lighthouse Chrome Extension. Once the JSON report is generated, it can be uploaded to the plugin via the WordPress Dashboard under Media -> Lighthouse Image Optimizer. By clicking 'Optimize Images,' users can effectively improve their site's loading speed and overall performance.
