History
Results are measured to our nearest Cloudflare server and depend on your device, browser, network load and distance. Other speed tests may show different numbers.
Check your internet speed in about 20 seconds: download and upload in megabits per second, plus ping and jitter in milliseconds. The test runs against the nearest Cloudflare data center, works the same on Wi-Fi, cable and mobile data, shows how much data it used and keeps a history on your device.
How to use
- Close downloads, streams and video calls on this device and, if you can, on others in your home.
- Tap Start. Ping and jitter are measured first, then download, then upload. The whole test takes about 20 seconds.
- Read the results below the gauge and tap any of them to copy it. Each run is saved in History on this device.
- To compare rooms or networks, run the test in each place and look at the history.
- The test runs against Utiluse’s own endpoint on Cloudflare’s network, answered by the data center nearest to you. Your internet provider’s own test may use a server inside its network and show higher numbers.
- Download and upload use several parallel connections with growing file sizes, so fast lines can be filled. The reported speed leaves out the first moments of each phase while connections ramp up.
- Ping is the median round-trip time of 10 small requests; jitter is the average change between consecutive pings. Lower is better for calls and games.
- A test uses about 15–200 MB depending on your speed; the exact amount is shown. On metered mobile data, test sparingly.
- Nothing is shared: no IP address or location is stored by the tool, and the history stays in your browser.
What the numbers mean
Download is how fast data reaches you, which matters for streaming, browsing and downloads. Upload is how fast you can send, which matters for video calls, cloud backups and sending large files. Both are in megabits per second (Mbps); divide by 8 for megabytes per second, so 100 Mbps moves about 12.5 MB each second.
Ping is the round-trip time of a small request, the median of 10 here. Jitter is how much ping varies from one request to the next. For gaming and calls, low and steady matters more than raw speed: under about 30 ms of ping and a few milliseconds of jitter feels instant, while jitter above 30 ms often causes choppy audio.
How the test works and why results differ
After ping, the test downloads and then uploads files of growing size over several parallel connections until the line is full, and leaves out the first moments of each phase while connections ramp up. Results vary with Wi-Fi signal, other devices on the network, the time of day and the server used. Your provider's own test may use a server inside its network and show higher numbers; a test to a public cloud reflects what you get from real websites more closely.
Frequently asked questions
What is a good internet speed?
For one person, 25 Mbps download handles HD streaming and calls. Households with several 4K streams, gamers and large uploads benefit from 100 Mbps or more.
Why is my speed lower than my plan?
Wi-Fi distance and walls, other devices using the connection, an older router or a busy time of day all reduce it. Test next to the router or with a cable to compare.
What is a good ping?
Under 20 ms is excellent, under 50 ms is fine for gaming and calls, and above 100 ms you will notice lag in fast games.
How much data does a speed test use?
About 15 to 200 MB depending on your speed; the exact amount is shown after each test. On metered mobile data, test sparingly.
Is Mbps the same as MB/s?
No. Mbps is megabits per second and MB/s is megabytes per second; one byte is 8 bits, so 80 Mbps equals 10 MB/s.
Is my IP address stored?
No. The tool keeps no IP address or location, and your test history stays in your own browser.
