Free Online Internet Speed Test
SpeedoTest is a free online internet speed test that helps you check how fast your internet connection is performing. Run a test to measure important connection metrics including download speed, upload speed, ping, and jitter.
Whether you use fiber, broadband, cable, DSL, Wi-Fi, or mobile internet, checking your connection can help you understand whether you are receiving the performance you expect.
If websites are loading slowly, videos are buffering, online games feel delayed, or video calls keep experiencing problems, an internet speed test can provide useful information about your connection.
What Does a Speed Test Measure?
Internet performance is more than just download speed. Your connection can also be affected by upload performance, latency, and network stability.
Upload Speed
Shows how quickly your device can send data to the internet. Upload speed matters for cloud backups, file uploads, livestreaming, and video calls.
Ping
Measures network response time in milliseconds. Lower latency is generally better for gaming, calls, and interactive applications.
Jitter
Measures variation in network latency. High jitter can make real-time applications feel unstable or inconsistent.
How this speed test works
Latency
We send small round-trips to the server and time each one. The average is your ping; how much each sample deviates from the last is your jitter — a rougher connection has higher jitter even at the same average speed.
Download
Several parallel connections stream randomized, incompressible data from the server at once — the same multi-connection approach industry tools use, since a single stream can't saturate most real-world links.
Upload
Your browser sends randomized payloads back to the server, which counts bytes and discards them. This measures how fast you can push data out — the number that matters most for video calls and cloud backups.
How to Check Your Internet Speed
Checking your internet speed is simple. You do not need to install software or create an account. Open SpeedoTest, start the test, and wait for the measurements to finish.
Once the test is complete, review your download speed, upload speed, ping, and jitter. If your results are consistently below what you expect, you can investigate your Wi-Fi, router, devices, or internet service.

What Is Download Speed?
Download speed is the rate at which information travels from the internet to your device. It is usually measured in Mbps, or megabits per second.
A higher download speed can make large downloads faster and provide more bandwidth for activities such as streaming video, browsing websites, and downloading applications.
What Is Upload Speed?
Upload speed is the rate at which information travels from your device to the internet.
It is important when uploading files, sharing photos and videos, using cloud storage, making video calls, and livestreaming.
Ping, Latency, and Jitter Explained
What is Ping?
Ping is a measurement of network response time. It is normally displayed in milliseconds (ms). Lower latency generally means that your connection responds more quickly, which can be especially important for online gaming, video conferencing, remote work, and other interactive services.
What is Jitter?
Jitter describes changes in latency over time. A connection with inconsistent latency can cause interruptions or unstable performance in applications that depend on a steady flow of network packets.
What Is a Good Internet Speed?
The right internet speed depends on what you do online, how many devices are connected, and how many people use the connection at the same time. The following ranges are general guidelines rather than strict requirements.
Basic browsing
Suitable for websites, email, messaging, and everyday browsing.
HD video streaming
A reasonable range for HD streaming and common online activities.
4K streaming
Higher bandwidth is useful for high-resolution streaming and multiple devices.
Online gaming
Gaming also depends heavily on ping, jitter, stability, and packet loss.
Multiple users
Higher speeds can help when several people stream, work, study, or game simultaneously.
Why Is My Internet So Slow?
If your internet speed test produces a result that is lower than expected, there may be several possible causes. Your internet plan is only one part of your overall connection performance.
Weak Wi-Fi signal
Being far away from the router
Walls or physical obstacles
Too many connected devices
Background downloads or uploads
Cloud backups and synchronization
Video streaming on other devices
Network congestion
Old or limited router hardware
Wireless interference
VPN usage
Internet service provider limitations
How to Improve Your Internet Speed
Move closer to your router
A stronger Wi-Fi signal can improve wireless performance. Try testing from different locations to see how much signal strength affects your results.
Use Ethernet when possible
A wired Ethernet connection can provide a more stable connection and can help determine whether Wi-Fi is limiting your internet performance.
Pause heavy downloads
Large downloads, cloud backups, software updates, and streaming can consume bandwidth while you are testing your connection.
Restart your router
Restarting your router can sometimes resolve temporary connectivity or performance problems.
Test at different times
Running speed tests throughout the day can help you identify whether your connection slows down during busy periods.
Check your internet plan
Compare your measured results with the speed advertised by your internet service provider. Keep in mind that actual performance can vary.
Wi-Fi Speed Test vs Wired Internet Speed Test
Wi-Fi can affect the speed that reaches your device. Distance from the router, walls, interference, wireless technology, router hardware, and other connected devices can all influence your results.
If you have access to an Ethernet connection, comparing a wired test with a Wi-Fi speed test can help you determine whether wireless connectivity is limiting your performance.
For mobile devices, your result can also vary depending on whether you are connected to Wi-Fi or a cellular network.
Check Internet Speed on Your Phone
SpeedoTest works directly in a modern web browser, allowing you to check your internet speed from a smartphone, tablet, laptop, or desktop computer.
When testing mobile internet, keep in mind that signal strength, network congestion, location, and the cellular technology available in your area can affect the result.
How Accurate Is an Internet Speed Test?
An internet speed test measures your connection under the conditions present at the time you run it. Because network conditions change, two tests performed at different times may produce different results.
For a more consistent test, close unnecessary applications, pause downloads and uploads, stop video streaming on other devices, and avoid bandwidth-heavy activity while testing.
If you are troubleshooting a connection problem, run several tests at different times and compare the results rather than relying on one measurement.
