About the internet speed test
This speed test measures how fast your connection really is right now — download, upload, ping, and jitter — by moving real data to and from Cloudflare's nearest edge location. It's the same path your transfers take, so the upload figure tells you what to expect when you send something big.
Upload speed is the number that matters for sending files, and on home broadband it's usually far lower than download. A 5 GB transfer takes about half an hour at 20 Mbps up, and a few minutes at 100 Mbps. Run the test, then plan around the result. Free, no account, nothing to install.
How the speed test works
- 1
Start the test
One tap. There's nothing to install and no account to create.
- 2
Both directions are measured
Latency first, then a real download and a real upload against the closest Cloudflare edge.
- 3
Read your result
Download, upload, ping, and busy ping, with a plain-language verdict on what your line can handle.
What the speed test measures
Measured at the edge
Tested against Cloudflare's nearest point of presence — the network your transfers use.
Upload, not just download
The number that decides how long sending a large file will actually take.
Ping and jitter too
Idle and busy latency, so you can see how the line behaves under load.
No tracking
The test runs in your browser. Results aren't stored or tied to you.
Any device, any browser
No app, no extension, nothing to install.
Free, no signup
Test as often as you like.
