What we built and why
speed-test.tools exists because testing your internet speed should be simple, fast, and free — without ads that make the page slow, trackers that follow you around the web, or registration walls that make no sense for a speed test.
We built this tool to give anyone an accurate, no-nonsense reading of their download speed, upload speed, and ping — from anywhere in the world, on any device, in seconds.
How the speed test works
Our speed test uses Cloudflare's global network as the primary measurement engine. Cloudflare operates servers in over 300 cities worldwide, which means the test measures your connection to a server that's geographically close to you — giving you an accurate picture of your real-world internet performance.
The test measures three things:
- Download speed — How fast data travels from the internet to your device. Measured in Mbps (megabits per second).
- Upload speed — How fast data travels from your device to the internet. Critical for video calls, file sharing, and live streaming.
- Ping (latency) — The round-trip time for a small packet of data. Measured in milliseconds (ms). Lower is better.
Our data collection policy
Speed test results are anonymized and may be used to build aggregate statistics about internet speeds by location and provider. We collect: download speed, upload speed, ping, ISP name, and general location (city/region). We do not collect: IP addresses in full (only the first three octets), personal information, or browsing history.
These anonymized measurements help us publish a public index of internet speeds by city and provider — freely available to researchers, journalists, and anyone interested in internet quality data.
Why trust our results?
Speed test results vary by tool because they measure different things. Our test uses Cloudflare's infrastructure, which is used by millions of websites and services globally. When you test with us, you're measuring your connection to the same servers that power a significant portion of the internet — making the results highly representative of your real-world experience.
