Dig into download-only, upload-only, ping, bufferbloat and Wi-Fi checks when you need more than a single score.
Measure one problem at a time
The full speed test gives four numbers. These tools isolate download, upload, latency or stability.
Understand your Mbps result
What the numbers mean, why tests disagree, and when latency matters more than bandwidth.
How this internet speed test works
Real browser measurements to a nearby edge — adaptive dial, Kbps/Mbps/Gbps display, Single or Multi connections.
Download & upload
Your browser moves real test data to a nearby edge and measures sustained throughput after discarding TCP ramp-up. Choose Single for one stream or Multi for four parallel connections.
Ping & jitter
Ping is the median round-trip of small probes. Jitter is the average change between samples — the figure that predicts stutter on calls and games.
Units & privacy
Switch the dial and result cards between Kbps, Mbps and Gbps. Measurements stay in your browser — no account, no stored personal results. Read the privacy notice.
This free internet speed test measures the path between your device and the closest public measurement edge — usually the same route your everyday traffic takes. Results can sit below an advertised plan because of Wi-Fi interference, a busy router, power-saving NICs, a VPN or peak-hour congestion. Run the test two or three times, compare Ethernet with Wi-Fi, and try Multi connections before you assume the ISP is at fault. The methodology guide walks through every stage.
If a number looks wrong, open the troubleshooting guides. For lag under load, run the bufferbloat test and the request loss test — a fast megabit score can still feel slow when latency spikes.
Internet speed test FAQ
Straight answers about accuracy, Single vs Multi, Kbps/Mbps/Gbps and how much data a run uses.
How does this free internet speed test work?
Your browser downloads and uploads real test data to a nearby measurement edge, then runs short latency probes. Download, upload, ping and jitter are reported from those transfers — nothing is invented or estimated from your plan.
What is the difference between Single and Multi connections?
Single uses one TCP stream, closest to a lone download or upload. Multi opens four parallel streams, which can fill a faster path that a single connection cannot saturate alone. Try both if your result sits below your plan.
Can I show speed in Kbps, Mbps or Gbps?
Yes. Use the Speed unit control under the dial. The speedometer ticks, the live readout and the download/upload cards all switch together. Internally the test still measures in megabits per second.
Why is my result lower than my internet plan?
Wi-Fi interference, a busy router, VPN software, background updates and peak-hour congestion all cut the measured figure. Compare a wired Ethernet run with Wi-Fi, then try Multi connections before contacting your ISP.
How much data does one speed test use?
It scales with your speed. A full run is capped around 100 MB total (about 60 MB download and 40 MB upload). Slower lines use less because each stage ends on its time budget first.
Is my speed test private?
Measurements run in your browser. We do not create accounts, do not store individual results on our servers and do not sell test data. Shared result links encode the numbers in the URL itself.
