How to use this speed test

This speed test is completely free. The whole test takes about 15 seconds and needs no installation. Follow these steps for the most accurate reading.

  1. Press the GO button. The test runs three stages automatically — latency, then download, then upload — and your result appears in the four cards.
  2. Stay on this page. Switching tabs or minimising the window can pause the test in some browsers and lower the measured speed.
  3. Close other apps first. Streaming, cloud backups and console updates all compete for the same bandwidth and will cut your result roughly in half.
  4. Use Ethernet where possible. A wired connection gives the truest reading; Wi-Fi loses 20–40% to interference and distance.
  5. Test at your normal busy time. A result at 3 am tells you little. Test around 9 pm to see what you actually experience.
  6. Run it two or three times. Take the middle figure — normal variation is within 10%.

Good connection

Download 25 Mbps+ with ping under 50 ms handles 4K streaming, HD video calls and several devices at once. 100 Mbps+ is comfortable for a large household.

Slow connection?

Below 10 Mbps video will buffer. The usual cause is Wi-Fi, not your broadband — moving closer to the router or switching to the 5 GHz band often recovers 30–50%.

Frequently asked questions

Is this internet speed test really free?

Yes — it is 100% free and always will be. There is no paid tier, no trial, no usage limit and nothing is ever charged. You do not need an account, and there is no "upgrade" prompt after your result. It stays free because it runs entirely in your browser.

Do I need to install anything or create an account?

No. This free page is a single self-contained HTML file. There is nothing to download, no account, and no personal data collected. Your results never leave your browser.

Can I run it on my phone?

Yes. The page adapts to any screen and works in Safari, Chrome and Samsung Internet. Mobile results depend on signal strength, so test where you normally use the internet.

Is this speed test accurate?

Yes. It measures real data transferred over multiple parallel connections — the same method used by major commercial providers. Small differences between runs are normal.

Why is my Wi-Fi slower than my plan?

Usually signal loss, interference from neighbouring networks, an ageing router, too many connected devices, or background traffic. Test with Ethernet: if the number jumps, your broadband is fine and Wi-Fi is the bottleneck.

What is the difference between Mbps and MB/s?

Mbps measures connection capacity in megabits; MB/s measures file download speed in megabytes. One megabyte equals eight megabits, so 100 Mbps downloads at roughly 12.5 MB/s.

Why does my upload speed differ so much from download?

Most home connections are asymmetric — download capacity far exceeds upload. DSL and cable commonly offer 5–20 times more download than upload. Fibre is often symmetrical.

Does running a test use a lot of data?

A full test moves roughly 20–60 MB. If your browser has Data Saver enabled, the test detects it and automatically runs a lighter payload.

Why does my upload result show "N/A"?

It means the upload endpoint was blocked rather than a problem with your connection — most often an ad blocker, privacy extension or strict firewall. Download, ping and jitter are still valid measurements.
