Free Internet Speed Test
tool80.com is a free online internet speed test that checks your download speed, upload speed and ping (latency) right in your browser. Run it on any device — no app to install, no sign-up, and your results are never uploaded or stored.
Press “Start test” to measure your connection.
What you'll see: Ping is the round-trip time to the server (lower is better); Download is how fast data comes to you; Upload is how fast data leaves you; Jitter is the variation in ping (stability). All four are measured against tool80.com's own edge, so the numbers reflect your real connection to the internet.
How the speed test works
This test runs entirely in your browser and talks only to tool80.com. There is no third-party tracker and nothing is saved on our side — the moment the test finishes, the numbers exist only on your screen.
- Ping. The page sends several tiny requests to the server and times how long each round trip takes, then reports the best latency and how steady it was (jitter).
- Download. The server streams a block of random, un-compressible data; your browser measures how long it takes to receive it and converts that into megabits per second.
- Upload. Your browser sends a block of random data back to the server and measures the time, giving your upload speed.
- Result. All four figures appear on the card above. Press “Run again” any time to compare — speeds naturally vary from moment to moment.

When should you run a speed test?
A quick speed test answers a lot of everyday questions about your connection:
- Is my plan delivering? Compare the result with the speed your ISP advertises.
- Video calls keep dropping? High ping or jitter explains choppy Zoom / Meet calls more than raw download speed.
- Slow uploads? Cloud backups, photo syncing and video calls all depend on upload speed — this test measures it directly.
- Moving rooms or switching Wi-Fi? Run the test in different spots to find the dead zones.
- Troubleshooting with support? A before/after measurement is the fastest way to show whether something changed.
Frequently asked questions
Is my data uploaded or stored?
No. The upload measurement sends random bytes to our server purely to time the transfer, and we discard them immediately. We do not log your result, your IP beyond standard server logs, or any personal information. The test is computed on your device.
Why do my results vary between tests?
Internet speed is shared and fluctuates with network congestion, Wi-Fi signal, background downloads and the time of day. Running the test a few times and taking the typical value is more meaningful than a single run.
What is a good ping / download / upload?
For most home use, a ping under 50 ms feels responsive, 50–100 Mbps download handles streaming and video calls comfortably, and 10–20 Mbps upload is enough for cloud backups and calls. Fiber plans will score far higher.
Does this test use a third-party service?
No. It measures against tool80.com's own servers, so it is fully self-contained and private. Some other speed tests route through partners; this one does not.
