Ping & Latency Test

Measure your connection's ping, jitter, and packet loss live — a quick latency test in your browser.

Pings a tiny file on our edge server about once a second and times the round trip — a live look at your connection's latency, jitter, and packet loss. Lower and steadier is better.

Check your latency

Input

Let it run

Output

Live ping in ms, e.g. 18 ms

Spot an unstable link

Input

Watch the graph

Output

Spiky bars = high jitter

Find packet loss

Input

Run for a minute

Output

Loss above 0% signals trouble

About this tool

This free online ping & latency test measures your connection's round-trip time, live, right in the browser. It shows your current ping in milliseconds along with min, average, and max, plus jitter and packet loss — the numbers that decide how smooth gaming, video calls, and streaming feel. No install or app required.

How to use

  1. The test starts automatically and pings about once a second.
  2. Watch the live ping, and let min/average settle for a few seconds.
  3. Check the graph for spikes (jitter) and the loss figure.
  4. Pause, resume, or reset the readings at any time.

Common uses

Checking latency before an online game or video call, diagnosing lag and stutter, comparing Wi-Fi in different rooms, or confirming a connection is stable after changing routers. Because browsers can't send raw ICMP pings, this uses a lightweight HTTP round trip to a nearby edge server, which reflects the latency your apps actually see.

Frequently asked questions

How does this ping test work?

It repeatedly fetches a tiny file from our edge server and times the round trip, once a second. That round-trip time is your latency (ping) in milliseconds — the tool shows it live along with jitter and packet loss.

What is ping and what's a good value?

Ping (latency) is how long a request takes to reach a server and come back, in milliseconds. Lower is better: under ~20 ms is excellent, under ~50 ms feels responsive for gaming and calls, and over ~100 ms starts to feel laggy for real-time use.

What is jitter?

Jitter is how much your ping varies from one moment to the next. Low, steady ping means low jitter and a stable connection; high jitter causes stutter in calls, streams, and games even if the average ping looks fine.

What is packet loss?

Packet loss is the percentage of pings that never got a reply. Any consistent loss above 0% points to a connection problem — a weak Wi-Fi signal, an overloaded network, or a bad cable — and causes drop-outs and rebuffering.

Is this a real ICMP ping?

No — browsers can't send raw ICMP pings for security reasons. This measures latency using an HTTP round trip to a nearby edge server, which reflects the same network delay your apps experience. It's a practical, browser-based latency test.

Why is my first ping higher?

The very first request may include connection setup, so it can read high. Let the test run for a few seconds and watch the min and average settle for a truer picture of your latency.

Does it use much data?

No. Each ping transfers only a few bytes. The test also stops automatically after about 40 pings (roughly half a minute) and pauses when you switch away from the tab, so it never keeps pinging in the background — press Run again for a fresh test whenever you like.
