Is your connection call-ready?
We measure your ping and jitter — the things that make a video call smooth or choppy — plus a quick speed estimate.
Press Start — we'll send a series of small requests to measure latency and jitter, then estimate your speed.
How the connection test works
Press Start and the page times a warm-up request followed by 12 tiny, cache-busted requests to this site. The median round-trip becomes your ping, and the average change between consecutive pings becomes your jitter — the two numbers that decide whether a video call feels smooth or robotic. Each bar in the chart is one request: shorter is faster.
For speed, we time one small (~160 KB) download and, in Chromium browsers, also read the Network Information API's connection type and downlink estimate. Everything stays between your browser and this website: the test only downloads a few of our own files and never uploads or stores anything about you.
What the readings mean
- Ping — the median round-trip time in ms. Under 60 ms is great for calls; under 120 ms is usable.
- Jitter — how much the ping wobbles between requests. Under 30 ms keeps audio steady; high jitter causes robot-voice.
- Down (est.) — a rough download-speed estimate in Mbps, from a small sample.
- Type — the browser's connection classification (e.g. 4G), where supported.
Connection test FAQ
Why is my ping different from other speed-test sites?
Every test measures the round trip to its own server, and ours measures small HTTP requests to this site — not a raw network ping to a server picked for closeness. Absolute numbers will differ between tools; what matters is that the reading is steady and in a healthy range for calls.
Why is the download estimate lower than my internet plan?
The estimate times one small (~160 KB) download, which can't saturate a fast connection, and the browser's own connection estimate is deliberately capped for privacy. It's a sanity check, not a benchmark — for an exact Mbps figure, use a dedicated speed test.
What's a good ping and jitter for video calls?
Under 60 ms ping with jitter under 30 ms is smooth-call territory — that's what this test grades as great. Up to about 120 ms is still usable. Beyond that, expect stutters: try a wired connection, move closer to the router, or pause big downloads.
Does the test upload anything or track me?
No. It only downloads a few tiny files from this same website and times how long they take. Nothing about you or your network is uploaded or stored — the requests never even leave this site's own domain.
Why does the connection type say n/a?
The Network Information API that reports connection type is only available in Chromium browsers like Chrome and Edge. Firefox and Safari don't expose it — the ping, jitter and speed measurements still work fine there.
