Frequently asked questions
Why do other speed tests show different results?
Each test measures to its own server, over its own route and with a different number of connections. Speed also changes during the day: in the evening your provider’s network is busier. To compare fairly, run the same test at different times — that’s what the history is for.
What is the difference between Mbps and MB/s?
Providers state speed in megabits, while browsers and torrent clients show megabytes. A byte has 8 bits, so 100 Mbps is about 12.5 MB/s, and in practice 10–11 MB/s because of protocol overhead.
Why is Wi-Fi slower than a cable?
Wi-Fi loses speed with distance, through walls and because of neighbouring networks, and older routers and the 2.4 GHz band hit their own ceiling. If the speed is below your plan, test from a computer connected by cable: that shows whether the provider or the Wi-Fi is to blame.
Where does the data go during the test?
Test data is downloaded from Cloudflare servers and sent back to them — random bytes, not your files. We don’t keep your results: the test history is stored only in this browser.
How much data does a test use?
On a fast connection, up to 350 MB per test. On mobile internet, turn on “Save data”: the test gets shorter and uses no more than 30 MB, though it is slightly less accurate on fast connections.
Why is there no packet loss?
Measuring packet loss honestly requires a separate server for real-time traffic, and a browser can’t do it without one. We chose not to show a made-up number. High jitter is an indirect sign of connection problems.
Where do the “can handle” thresholds come from?
From the requirements of the services themselves: Netflix needs 15 Mbps for 4K and YouTube 20 Mbps, Zoom needs 3.8 Mbps down and 3.0 Mbps up for a 1080p call, NVIDIA GeForce NOW needs a ping below 80 ms, and YouTube Live needs 12 Mbps of upload for a 1080p 60 fps stream. For 4K we use 25 Mbps to leave some headroom.
Is it free?
Yes, it’s free, with no sign-up.
