Website Speed Test

Check real website speed metrics using live Lighthouse data

Live

Enter any public URL to analyze performance, Core Web Vitals, and loading behavior. Results include mobile or desktop scores plus actionable metrics like LCP, FCP, TBT, and CLS.

Tip: run tests for both mobile and desktop, then improve high-impact issues first (large images, render-blocking scripts, and slow server response).

Images are the #1 cause of slow pages. Reduce image file size with our free image compressor to improve your speed score.

Slow DNS resolution increases your Time to First Byte (TTFB). Verify your DNS setup with our free DNS checker.

How to use Website Speed Test

Use the Website Speed Test to review loading performance before and after website changes. It helps site owners, developers, marketers, and SEO teams spot slow pages, large assets, and performance issues that can affect user experience, conversions, and search visibility. Run a baseline, optimize images or hosting, then test again so you can tell whether a change actually helped.

Step 1: Start a fresh test

Close heavy downloads and pause VPN if you want a reading closer to your normal network path.

Step 2: Measure download, upload, and latency

Run the test and note Mbps plus ping/jitter—repeat once to rule out a one-off spike.

Step 3: Compare with expectations

Match results against your plan speed and troubleshoot Wi‑Fi interference or ISP issues if numbers are consistently low.

Frequently asked questions

Common questions people ask before using this tool.

Why does page speed matter?

Fast pages usually provide better user experience and can support stronger SEO and conversion outcomes, especially on mobile networks.

Should I test after image compression?

Yes. Test again after compressing or resizing images to measure whether file-size changes improved load time.

Can results vary?

Yes. Network conditions, server load, caching, CDN location, and time of day can affect speed test results—compare multiple runs.

Is this the same as an internet speed test?

No. A website speed test evaluates how a page loads; an internet speed test measures your connection throughput. Use both when diagnosing “the site feels slow.”
