Internet Speed Test — Free Download, Upload & Ping Check

Test your internet connection speed instantly with our free online tool. Measure your download speed, upload speed, and ping latency in seconds — no signup, no ads, no limits. The test runs entirely in your browser using Cloudflare's global edge network for accurate, real-world results.

What We Measure

Download Speed — how fast data travels from the internet to your device. This is what matters most for streaming, browsing, and downloading files.
Upload Speed — how fast data travels from your device to the internet. Important for video calls, live streaming, and uploading files.
Ping (Latency) — the round-trip time for a small data packet. Low ping is critical for online gaming and real-time applications.

How the Test Works

The tool downloads and uploads data chunks to Cloudflare's nearest edge server, measuring the throughput in real time. Multiple samples are averaged for stability, and the highest-throughput measurement determines your reported speed. Cloudflare's network has a presence in over 300 cities worldwide, so you're always testing against a nearby server.

Why Test Your Speed?

Verify you're getting the speed you pay for, diagnose slow connections, compare WiFi vs. ethernet performance, test before and after router changes, or confirm your VPN isn't slowing you down.

Tips for Accurate Results

Close other tabs and applications that use bandwidth. Disconnect VPNs and proxies. Test over ethernet for maximum accuracy. Run the test twice — the second one is usually more accurate as the connection warms up.

Frequently Asked Questions

How accurate is this speed test?

The test uses Cloudflare's edge network and typically reports results within 5-10% of dedicated speed test services like Ookla. Factors that affect accuracy include your browser, CPU load, WiFi signal strength, and time of day. For best results, test over ethernet and close other apps.

What's a good internet speed?

For basic browsing and email: 5-10 Mbps download. For HD streaming: 15-25 Mbps. For 4K streaming: 25-50 Mbps. For online gaming: 25+ Mbps with low ping. For video calls: 5 Mbps upload. For live streaming: 10+ Mbps upload.

Why is my speed lower than what I pay for?

WiFi signal loss, router distance, peak-hour congestion, and device limitations all affect real-world speeds. ISPs advertise "up to" speeds — actual performance depends on many factors. Test with an ethernet cable to rule out WiFi issues.

Does this test use my data?

Yes, running the test downloads and uploads real data (about 25-30 MB per test). On mobile data plans, this may count against your data allowance. The test is unlimited in frequency but not in bandwidth usage.

Why does my ping matter?

Ping (latency) measures the delay in round-trip communication. Low ping (<30ms) is essential for gaming, video calls, and VoIP. High ping causes lag, stuttering, and dropped connections. Ping depends more on distance to the server than on raw bandwidth.
