How it works
The test ramps through progressively larger transfers. That avoids estimating a fast connection from a tiny fixed payload.

INTERNET SPEED TEST
Measure download, upload, unloaded latency and jitter using Cloudflare edge-network measurements.

Measurement traffic runs against Cloudflare edge infrastructure. VPNs, Wi-Fi conditions, browser load, device limits and routing can change results.
Read the result
Higher throughput is better. Lower latency and jitter are generally better for gaming, calls and other real-time traffic.
