Network quality check
Internet Speed Test
Measure download speed, upload speed, latency, and jitter against Cloudflare's edge network. No signup required.
One-click test
Check your connection quality
Close large downloads and VPN connections for a more representative result.
A complete test may transfer roughly 50–160 MB, depending on connection speed.
Connection summary
Test complete
The browser sends test requests to Cloudflare. FileTiny does not store your result, but Cloudflare processes the network requests. Results describe the route to Cloudflare and can differ from an ISP's local test node.
Get a more accurate speed test
Wi-Fi signal quality and interference can limit the measured speed before your broadband connection does.
Cloud backups, video streams, downloads, and other devices share the same connection during the test.
Compare results at different times. Congestion, Wi-Fi conditions, and routing can change throughout the day.
Network tool guide
What does the internet speed test measure?
The browser sends download, upload, and small latency requests to Cloudflare's edge network. It measures download speed, upload speed, idle latency, loaded latency, and jitter to describe the current connection experience.
How to run a more representative test
- Pause large downloads, cloud sync, video streams, and other bandwidth-heavy activity.
- Use Ethernet when checking the speed delivered to your router or home connection.
- Start the test and keep the page open until both download and upload measurements finish.
- Run two or three tests in the same conditions and compare the results.
How to understand the results
- Download speed affects web content, file transfers, and video streaming.
- Upload speed affects video calls, cloud uploads, live streaming, and sending large files.
- Lower idle latency usually makes browsing, remote desktops, and online games feel more responsive.
- High loaded latency means real-time apps are more likely to stutter when the connection is busy.
Why speed test results vary
Wi-Fi signal, device performance, background traffic, other devices, ISP congestion, and network routing all affect a test. This page measures the current route to Cloudflare and should not be the only evidence used to validate an ISP access line.
FAQ
Internet speed test frequently asked questions
Why does the speed test result change each time?
Wi-Fi signal, background traffic, other devices, time of day, and network routing all affect the result. Pause other traffic and run two or three tests for comparison.
Is this the same as my ISP line speed?
Not exactly. The result describes the current route from this device to Cloudflare's edge network and can differ from an ISP's local test node or access-line rate.
How much data does a speed test use?
A complete test usually transfers about 50–160 MB. Faster connections may transfer more data to obtain a stable measurement sample.
