How to use it

  1. 01

    Close anything using the connection

    Pause downloads, streaming and cloud backups, and get other people off the network if you can. Background traffic is the most common reason a test under-reports.

  2. 02

    Choose how you are connected

    Test over wifi to measure what your devices actually get, or plug into an Ethernet cable to measure the true line speed. Testing both is how you tell a wifi problem apart from a provider problem.

  3. 03

    Run the test

    Press start and stay on the tab while the gauge runs. The test measures download, then upload, then ping and jitter, and takes well under a minute.

  4. 04

    Read all four numbers

    Download and upload are throughput in Mbps; ping is delay and jitter is how steady that delay is. A high download speed with poor jitter still makes calls and gaming feel bad.

  5. 05

    Repeat before you conclude anything

    Run it two or three times, including once during evening peak hours, and compare against the plan you pay for. A single result is a snapshot, not evidence.

About Internet Speed Test

Check your real internet speed instantly with this browser-based speed test. Measure your download and upload speeds, ping, and jitter without leaving your browser. Our wifi speed test and broadband speed checker run right on your device, giving you accurate results in seconds. No signup needed, completely free to use whenever you want to monitor your connection.

This internet speed test measures the key metrics that affect your online experience. Your mbps test shows download and upload speeds, while ping and jitter measurements reveal latency and consistency. The live gauge lets you watch your connection in action as data flows between you and our test servers. All measurements happen on your device—your results never leave your computer.

Use this tool whenever you need to diagnose connection problems or verify your broadband speed is what you're paying for. Whether you're troubleshooting slow wifi or checking speed in different rooms, the shareable result card lets you compare speeds over time and with others. Run the test as often as you like, completely free and without any account needed.

It works as a speed test without an app on any device with a browser — Android, iPhone, Windows, Mac, a smart TV, even a work laptop where you cannot install software. Nothing is downloaded and nothing is installed, so you can test a hotel connection, an office guest network, or a friend's wifi in a few seconds. That also makes it a fair way to compare the same connection across two devices: run it on your phone, then on your laptop, standing in the same spot.

The test is useful for checking any broadband or fibre connection against the plan you actually pay for, whether that is a Jio Fiber, Airtel Xstream, BSNL or ACT line in India, or a cable and fibre plan in Canada. Providers advertise a peak speed rather than a guaranteed one, so the honest way to judge a plan is to run the same test several times across a week — including one evening test during peak hours, when a shared line is at its most congested — and compare the pattern rather than a single number.

One detail trips almost everyone up: internet plans are sold in megabits per second (Mbps) but downloads are usually shown in megabytes per second (MB/s), and there are eight bits in a byte. A 100 Mbps connection running perfectly downloads at roughly 12.5 MB/s, not 100. If your browser shows a file arriving at around one-eighth of your plan speed, your connection is doing exactly what it should, and the number to check is the one this test reports in Mbps.

Frequently asked questions

What's a good internet speed?
It depends on your needs. For streaming video, 5-10 Mbps download is typical. Video calls need about 2.5 Mbps each direction. Gaming usually wants 15+ Mbps download with low ping. Check what speed tier you're paying for from your ISP and use this speed test to verify you're actually getting it.
Why do my speed test results vary?
Internet speed naturally fluctuates based on network congestion, wifi signal strength, and what else is using your connection. That's why ping and jitter matter—they show consistency, not just raw speed. Test multiple times at different times of day for a real picture of your broadband speed. Close other apps and devices before testing for your most accurate mbps measurement.
What's the difference between download and upload speed?
Download speed is how fast data comes to you (used for browsing, streaming, video calls). Upload speed is how fast you send data out (used for video calls, file uploads, streaming). Most people need faster download than upload, but if you work from home or stream content, upload speed matters more. This internet speed test measures both to give you the full picture.
How accurate is this speed test?
Browser-based speed tests measure real-world performance between you and our test servers. Your results depend on connection quality, network conditions at test time, and server location. For the most accurate mbps test, run it multiple times and check for consistent results. If speeds are far below your ISP package claims, contact your provider or try moving closer to your wifi router.
Why is my download speed slower than the plan I pay for?
Almost always it is the last few metres rather than the line itself. Wifi is the usual culprit: distance from the router, walls, and older 2.4 GHz-only devices can each cut throughput by half or more, so plug into an Ethernet cable and retest to see the true line speed. Other common causes are peak-hour congestion on a shared connection, another device streaming or backing up in the background, an old router that cannot forward more than a few hundred Mbps, and plans advertised as "up to" a speed rather than guaranteed. If a wired test at a quiet hour still comes in far under your tier, that is the evidence to take to your provider.
What is jitter, and what counts as good?
Jitter is how much your ping varies from moment to moment. Ping tells you the delay on one packet; jitter tells you how consistent that delay is across many. It matters because live audio and video have to play back at a steady rate — inconsistent arrival times are what produce robotic voices, frozen frames and stutter, even on a connection with plenty of Mbps. Under about 5 ms is excellent, under 20 ms is fine for calls and most gaming, and consistently over 30 ms is worth investigating. High jitter with a healthy download speed usually points at wifi interference or an overloaded router rather than your provider.
How much internet speed do I need for 4K Netflix?
Netflix recommends about 15 Mbps for 4K (Ultra HD), 5 Mbps for 1080p and 3 Mbps for 720p, and other services are broadly similar — YouTube suggests around 20 Mbps for 4K, Disney+ about 25 Mbps. Those figures are per simultaneous stream, so a household running two 4K streams while someone else is on a video call wants roughly 40-50 Mbps of headroom, not 15. Steady speed matters more than peak here: 4K buffers because throughput dips mid-stream, so check that repeated tests stay consistent rather than chasing the highest single result.
Why is my speed test result different from my ISP's own test?
Provider speed tests usually connect to a server inside the provider's own network, so the result reflects the link to their nearest node rather than the wider internet your traffic actually crosses. That number is genuinely useful for ruling out a fault on your line, but it tends to read higher than real-world performance. Running both is the informative move: if your provider's test is fast and an independent test is slow, the bottleneck is likely beyond their network or at peak-hour capacity; if both are slow, the problem is your line, router or wifi.
Does a VPN affect my speed test?
Yes, and often substantially. A VPN encrypts your traffic and routes it through an intermediate server, which adds distance and processing — expect a noticeable drop in download speed and a clear rise in ping, especially if the VPN server is in another country. Turn the VPN off before testing if you want to measure your actual connection, then test again with it on if you want to know what your day-to-day speed looks like while it is running.
Is this speed test free, and does it need an app or signup?
It is completely free, needs no account, and installs nothing — the entire test runs in your browser on the device you are holding. There is no app to download for Android or iPhone and no software for Windows or Mac, which is why it works on locked-down work machines and smart TVs. Run it as often as you like.
Is Internet Speed Test free to use?
Internet Speed Test is 100% free — no signup, no watermarks and no usage limits. It’s one of 200+ free tools we build and give away.
Is my camera or mic data uploaded?
No. All sensor data is processed live on your device and never leaves it or gets stored.
