Internet speed test
A real measurement against this site’s own edge servers — download, upload, latency and jitter, accurate well past 1 Gbps. No ads, no sign-up, nothing stored.

Information
What these numbers mean
Download
How fast data reaches you. Streaming 4K needs ~25 Mbps; a household of heavy users is comfortable above 100 Mbps.
Upload
How fast data leaves your device. Video calls need ~5 Mbps; cloud backups and live streaming benefit from 20 Mbps or more.
Ping
Round-trip latency to the nearest edge server, measured on an already-open connection so handshakes never inflate it.
Jitter
Variation between latency samples. Below 10 ms keeps voice and video smooth; higher values cause stutter and dropouts.
Loaded latency
Latency measured while download and upload traffic saturate the connection. Its increase over idle ping is bufferbloat — lower is better for calls and gaming during heavy use.
How the test works
Six parallel download streams and three upload streams are opened to this site’s own edge network using incompressible random data. The first 1.5 seconds of each phase is discarded so connection ramp-up cannot distort the result. Live readings use a rolling window to remove packet-batching spikes; the final result is anchored to all bytes transferred across the stable window.
Getting an accurate reading
Close other tabs and downloads, pause streaming on other devices, sit close to your router or use a wired connection, and run the test two or three times to see a consistent range.
Privacy
No result is ever persisted. Speeds and samples exist only in this browser tab and vanish on reload — nothing is written to a database, a log or a cookie. The transferred payload is random filler discarded on both ends. The only value kept on your device is your privacy-mode preference. Turn privacy mode on and the provider lookup — the single third-party request on this page — never happens.
Why results differ from your plan
Advertised speeds are measured at the line, not at your device. Wi‑Fi, older hardware, VPNs and peak-hour congestion all reduce what actually arrives.
Frequently asked questions
Is this internet speed test accurate?+
Yes. It measures real throughput by transferring incompressible data over multiple parallel connections to this site's own edge network, discarding the ramp-up period and averaging the stable window — the same method professional speed tests use.
What is a good download speed?+
25 Mbps handles 4K streaming on one device, 100 Mbps is comfortable for a busy household, and 300 Mbps or more suits large downloads, cloud work and many simultaneous devices.
What is a good ping and jitter?+
Ping under 30 ms feels instant for gaming and calls, 30-80 ms is fine for everyday use, and above 100 ms is noticeable. Jitter below 10 ms keeps voice and video smooth.
Why is my speed lower than the plan I pay for?+
Advertised speeds are measured at the line, not at your device. Wi-Fi distance, older routers, VPNs, background downloads and peak-hour congestion all reduce what actually reaches your browser.
Does the test store my data?+
No. Nothing is recorded. The transferred payload is random filler discarded on both ends, and results stay in your browser for the session only.
Results depend on your device, Wi‑Fi, and the route between you and the nearest edge location. For the most accurate numbers, close other tabs and downloads, and test over a wired connection when possible.
