How to use
- 1 Close other downloads and video calls, then press Start test.
- 2 Download and upload are shown in megabits per second (Mbps). Ping is the time for a tiny message to reach the server and come back; jitter is how much that time changes. Lower is better for both.
- 3 For video calls, about 5 Mbps both ways and a ping under 100 ms work well. For 4K video, aim for 25 Mbps download or more.
- 4 The test runs in your browser against Cloudflare's servers near you. Our server never sees your results.
