What we do
internet-speed-test.online is a free tool that measures the real performance of your internet connection - Download speed, upload speed, ping, jitter and packet loss - Directly in your browser, on any device, with no app to install and no account to create.
We pair the test with a growing library of plain-English guides so the numbers actually mean something. Whether you want to know how a speed test works, how much speed you need, or which providers are fastest, there's a clear answer here.
How the test works
Your browser downloads a stream of data from our server and times how fast it arrives, then sends data back to measure upload, and pings the server repeatedly to measure latency, jitter and packet loss. All measurement happens on your device - We simply provide the endpoints to test against. For the full method, see what is a speed test.
Our principles
- Privacy first. We don't store your results and we don't require an account. Your IP is used only to show your provider on the page. See our privacy policy.
- Accuracy. We use a straightforward, transparent method and explain exactly how to get a reliable reading.
- Clarity. Every metric is explained without jargon, so you can act on your results.
- Free. The test and all guides are free, with no paywalls.
Provider speeds and city averages across this site are representative planning estimates compiled from public information - They're meant for comparison, not as guarantees. The one number that's truly yours is the live test. Run it here.
