A free online internet ping test: browser-based latency probe that pings any target URL and reports round-trip time over several runs.
Ping — also called latency — is the time a small data packet takes to travel from your device to a server and back, measured in milliseconds. It is the delay behind everything you do online: every click, keystroke, and word in a video call must complete that round trip. Low ping feels instant; high ping shows up as lag in games and awkward pauses in calls. A download speed test on its own tells you half the story, which is why any real internet speed check also measures ping.
Yes — 27 ms is very good, comfortably in the range competitive players aim for (roughly 20–30 ms or better). As a general guide: under 50 ms feels responsive for almost any game, 50–100 ms is playable with occasional delay, and above 150 ms you will feel noticeable lag. Ping results depend on distance to the server, so run this test against the region you actually play in for a number you can trust.
Most remote jobs work fine for one person on about 25 Mbps download and 3 Mbps upload or higher. Video calls typically need 4–8 Mbps in each direction, while email, web browsing, and cloud documents use very little. If two people share the connection and are on calls at once, plan for 50 Mbps or more. Latency matters too: a high-ping connection can feel slow on calls even when the download speed looks fine, so check both halves of your internet speed.
Yes — for a single remote worker, 20 Mbps handles email, browsing, cloud documents, and one video call with room to spare. Watch the other two numbers instead: an upload below 3 Mbps makes video calls look rough on the other end, and high ping adds lag even at a good download speed. Run a check at a busy time of day a few times to see your steady real-world speed, not just the peak.
Test at least 30 minutes before the call using the same network you will sit on — wired ethernet is steadier than wifi, so prefer it for interviews. You want three things: download and upload comfortably above the 4–8 Mbps a video call needs, and a ping under 100 ms to the meeting's region. If your wifi is weak, move closer to the router or plug in a cable. This page checks the ping half of that; pair it with a bandwidth test for the full picture.
You do not need an app or an account. This ping test runs free in your browser — type in a target URL and it measures round-trip latency over several runs, so nothing is downloaded, installed, or uploaded. The well-known speed test services cover ping, download, and upload for free; this one is handy because it works against any end point you choose, not just a server picked for you.
🔒 This tool runs entirely in your browser. Nothing is uploaded or stored.

This tool measures ping and latency — the round-trip time to a target URL over several runs. The download and upload megabits that a "download speed test" or "upload speed test" reports are a separate part of a complete internet bandwidth test. If lag and responsiveness are what you want to check, this free ping test is the right tool; pair it with a bandwidth test for your full internet speed result.
Yes. It runs in your browser no matter how you connect, so it works as a wifi speed test, an ethernet speed test, or a broadband connection test. Run it once over wifi and once wired into the router to compare the two — that is the fastest way to spot a weak wifi signal dragging your internet speed down.
Wifi adds a little latency that a cable does not: every packet travels through the air, and distance or interference adds delay. A 1–5 ms difference is normal; a much larger gap usually means a weak wifi signal. Run this ping test next to the router over wifi, then again over an ethernet cable, and compare the round-trip times to find the bottleneck.
Under 50 ms feels natural on a video call; 50–100 ms is fine for most meetings; above 100–150 ms you start talking over people and the call feels laggy. Ping usually matters more than download speed for interactive calls, because a fast download cannot hide a slow round trip.
Yes — paste in the domain or IP of the server you care about, such as your game's regional server or the VPN you connect to for work, and the tool reports round-trip time over several runs. Ping depends on where the server lives, so test the one you actually use instead of assuming one number fits everything.
