About this test
The speed test measures how much data your connection can download per second (Mbps), plus latency (ping), the response time, and jitter, the variation of that response. Low latency and jitter are essential for video calls and gaming.
The measurement uses a public bandwidth test server and runs entirely in the browser. Values vary with time of day, signal quality and how many devices share the network.
Privacy: this tool runs entirely in your browser. No image, audio or device data is recorded or sent to any server.
Frequently asked questions
Why is my speed lower than my plan?
Losses from distant Wi-Fi, many connected devices or peak hours are normal. Test near the router and over cable when possible to compare.
Does the test use my data plan?
Yes, it downloads some megabytes to measure speed. On mobile data, prefer testing on Wi-Fi to save your quota.
