How this tool works
Desktop conditions differ from mobile, so this test runs the desktop strategy separately. It reports the actual metrics returned by PageSpeed Insights and never invents a score when a measurement fails.
FREE PERFORMANCE TOOL
Desktop Website Speed Test
Measure desktop performance with real Lighthouse data and clear, prioritized recommendations.
Understand your results
Use the score as a diagnostic snapshot rather than a guarantee. Compare lab metrics, available field data and estimated savings to understand which technical changes deserve attention first.
Practical optimization tips
Fix slow server responses and render-blocking assets first. Then reduce JavaScript work, compress images, improve caching and verify that font loading does not delay visible content.
Frequently asked questions
Is this an official Google or AI score?
No. PageSpeed metrics come from Google where applicable; QuickWebify SEO and readiness scores are transparent technical indications.
Do you store the URL?
Results are cached temporarily to prevent duplicate load. No registration or personal details are required.
Can this replace a full audit?
No. It is a focused first check. A full audit considers templates, multiple URLs, analytics, business goals and implementation details.
