How does the speed test work?
Your browser downloads sample data from a test server and measures how fast bytes transfer. Ping is measured by timing how long small requests take to round-trip. Jitter is the variation in ping over time.
What's a "good" download speed?
For most households: 25 Mbps is enough for HD streaming, 100 Mbps handles 4K and gaming, 500+ Mbps is overkill unless you have 4+ heavy users on the same connection.
What do "ping" and "jitter" mean?
Ping (latency) is how long a tiny request takes to reach the server and come back — under 30 ms is excellent, 30-60 ms is good, over 100 ms hurts gaming and video calls. Jitter is how much your ping varies — high jitter causes choppy calls and gameplay even when bandwidth is fine.
Why don't you test upload speed?
Most users only need to know download speed — that's what affects streaming, browsing, and gaming. Upload mainly matters for video calls and large file uploads, and free upload tests are less reliable than download. We focus on what matters most for the typical user.
Why is my speed lower than what I'm paying for?
Common causes: WiFi congestion (try wired Ethernet to rule it out), other devices using bandwidth, ISP throttling, an outdated router, peak-hour congestion in your neighborhood, or the test server being far from you. Run multiple tests at different times to spot patterns.
Is this test accurate?
It's accurate to within ~5-10% of dedicated tools like Speedtest.net for most connections. Variance comes from server distance, browser overhead, and other tabs using bandwidth during the test. Closing other tabs and using Ethernet gives the most reliable result.
Do you store my IP or test results?
No. Tests run entirely in your browser, results stay on your device. We log nothing.
