A free, no-sign-up speed test that measures download, upload, ping and jitter directly in your browser.
Your browser downloads and uploads small amounts of test data to a network testing server and measures how long it takes, then converts that into megabits per second (Mbps).
Network conditions change constantly — Wi-Fi interference, other devices using bandwidth, and your ISP's load all cause natural variation. Run the test a few times for a reliable average.
25 Mbps download is enough for HD streaming; 100+ Mbps comfortably handles multiple 4K streams and devices. For upload, 3–10 Mbps is enough for most video calls and cloud backups.
