Ever wonder why your shots don’t register, your character teleports across the map, or your game suddenly freezes mid-match despite having decent internet speed? The culprit is almost never your download speed — it’s packet loss.
Our free Packet Loss Test tool lets you diagnose your connection in real time, right from your browser. No downloads, no installs, no sign-up required.

What Is Packet Loss?
When your device communicates with a game server, it sends thousands of tiny data packets every second. If some of those packets never arrive — or arrive too late to be useful — that’s packet loss. Even a loss rate of 1–2% can cause noticeable lag spikes, rubberbanding, and hit registration failures in competitive games like Valorant, BGMI, Free Fire, or Call of Duty.
What This Tool Tests
Our packet loss tester runs two types of checks simultaneously:
HTTP Ping Simulation measures how reliably your browser can reach a target server over TCP. This reflects the stability of your connection to game servers and CDN endpoints.
WebRTC UDP Test uses a real-time data channel — the same underlying technology used by voice chat apps and multiplayer games — to measure UDP packet delivery. Since most games run on UDP, this is the most relevant test for gamers.
Together, they give you a complete picture: your overall loss rate, average ping, minimum and maximum latency, and jitter (the variation in ping that causes stuttering and inconsistent gameplay).
How to Use It
You can customise the test to match your exact use case. Adjust the packet size, ping frequency, test duration, and acceptable delay threshold using the sliders. Or simply pick a preset — Gaming (FPS), MOBA/RTS, VoIP, or Video Streaming — and the tool will configure itself automatically. Choose the server region closest to you for the most accurate results.
Once the test completes, you’ll get a grade from S to F, a breakdown of lost and late packets, and a gaming impact assessment that tells you which game types your connection can handle right now.
What’s a Good Result?
- 0% loss — Perfect. Play anything without worry.
- Under 1% — Excellent. Suitable for all competitive games.
- 1–2.5% — Fair. Casual gaming is fine; ranked play may feel inconsistent.
- Above 5% — Critical. You will experience lag, disconnections, and poor hit detection.
Found Packet Loss? Here’s What to Do
If your results are showing anything above 1%, don’t panic — most causes are fixable. Check out our guide on How to Fix Packet Loss on PC where we walk through the most common causes (Wi-Fi interference, outdated drivers, ISP throttling, overloaded routers) and how to solve them step by step.
Run this test before and after trying any fix to see exactly what’s working.
