Check how fast your connection really is - download, upload, ping and jitter in about half a minute. Works on phone and computer, with nothing to install.

It opens several parallel connections to a nearby server and measures the data that actually arrives (and leaves) after a short warm-up, which is how most speed tests work. For the best reading, close other downloads, streaming and VPNs, and test close to the router.
Plans list the maximum speed on the wire. Wi-Fi distance, other devices, an old router, your phone or laptop, and busy hours all reduce what you actually get. Try the test next to the router, or over a LAN cable.
Ping is how long a tiny message takes to reach the server and come back, in milliseconds. Jitter is how much that time changes from one message to the next. Low ping and low jitter matter most for gaming and video calls.
It depends on your speed, because the test runs for a fixed time. On a fast connection a standard test can use 50-150 MB, so use the Quick option on a limited mobile data plan.
