Internet speed test
Press Start to measure your download speed, upload speed, ping and jitter. The test runs in your browser with no app and no sign-up, then tells you what your connection is good for, from 4K streaming to video calls and online gaming.
Free · No sign-up
How to use it
- Pause downloads, video streams and cloud backups on your devices, so they do not share the line during the test.
- Press Start test. The tool measures ping and jitter first, then download speed, then upload speed.
- Wait about 25 seconds for all three phases. You can stop the test at any time.
- Read your results in Mbps and ms, and check the list of what your connection can handle. Run the test again at another time of day to compare.
Why use this tool
Download, upload, ping and jitter
All four numbers that matter, measured in one run with a live gauge.
Several parallel streams
Like the big speed test sites, the test uses several connections at once so fast fibre lines are measured properly.
Plain-language verdict
See at a glance whether your connection is good enough for 4K streaming, video calls, gaming and large uploads.
History in your browser
Your last 10 results are kept on this device only, so you can compare times of day or Wi-Fi and cable.
No app, no account
Runs in any modern browser on phones, tablets and computers, with no Flash, plugin or sign-up.
Data aware
Each phase stops after a time or data limit, and a quick mode keeps data use low on mobile plans.
What the numbers mean
| Result | What it measures | Good value |
|---|---|---|
| Download | How fast data reaches you, used for streaming, browsing and downloads | 25 Mbps or more for a household |
| Upload | How fast you can send data, used for video calls, cloud backups and posting videos | 5 Mbps or more |
| Ping | Time for a tiny message to reach the server and come back | Under 40 ms for gaming |
| Jitter | How much the ping changes from one moment to the next | Under 15 ms for smooth calls |
How much speed do you need?
- Web browsing, email and music: 1–5 Mbps per person.
- HD video (1080p): about 5 Mbps per stream.
- 4K video: about 25 Mbps per stream.
- Video calls: 3–4 Mbps down and up for HD group calls.
- Online gaming: speed matters less than a low, steady ping.
- Add the needs of everyone who uses the internet at the same time.
Why your result can be lower than your plan
Internet plans are sold as 'up to' speeds. Wi-Fi is often the biggest limit: walls, distance from the router and busy channels can cut the speed in half. For the true line speed, test on a computer connected to the router with a cable.
Other things that lower the result are other devices using the connection, an old router or network adapter, a VPN, a busy time of evening, and the distance between you and the test server. Run the test a few times, at different times of day, before you contact your provider.
How this test works
The tool first sends a series of tiny requests to measure ping and jitter. It then downloads random data over several connections at once for a fixed time, and finally uploads random data the same way. The first moments of each phase are left out, so the slow start of a new connection does not drag the result down.
Results are measured between your device and the Amanta AI server, so they show real-world speed to a website. They can differ from tests that pick a server inside your provider's own network.
Frequently asked questions
What is a good internet speed?
For a typical home, 25–100 Mbps download and at least 5–10 Mbps upload is comfortable. Households with several 4K streams, gamers or people who upload large files benefit from 200 Mbps or more.
What is the difference between Mbps and MB/s?
Speeds are measured in megabits per second (Mbps). File sizes are shown in megabytes (MB). One byte is 8 bits, so 100 Mbps downloads about 12.5 MB per second.
What is a good ping for gaming?
Under 20 ms is excellent, 20–50 ms is good and 50–100 ms is playable for most games. Above 100 ms you may notice lag. A steady ping with low jitter matters as much as a low one.
Why is my upload so much slower than my download?
Most cable and DSL plans are asymmetric and give much less upload than download. Fibre plans often offer equal upload and download speeds.
How much data does the test use?
It depends on your speed. A standard test on a fast line uses up to about 350 MB, and a slow line uses much less. The quick option halves the time and data.
Is the speed test accurate on Wi-Fi?
It measures the speed you really get on that device and Wi-Fi network. To check the speed of the line itself, connect a computer to the router with a cable and test again.
