Turn a speed report
into your next move.

Import a Lighthouse or PageSpeed JSON report. See the measured scores, the page tested and the details worth improving.

How to get a report
  1. Open your page in Chrome, then open DevTools → Lighthouse.
  2. Choose Mobile or Desktop and Analyze page load. Wait for the report.
  3. Use the report menu to save JSON, then import that file here.

Already use the Lighthouse CLI or the PageSpeed API? Import their JSON output directly. HTML reports are not supported.
