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.
CheckMyMic's connection test is a free online network check that runs entirely in your browser: it measures your ping (latency), jitter and a download-speed estimate, then tells you plainly whether your internet is ready for video calls. Your test data stays on your device.
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.
