Why Use Our Free Speed Test?
Unlike other speed tests that require Flash or plugins, our tool runs entirely in your browser using modern Web APIs. No downloads, no signups, no cookies. Test your internet connection speed quickly and accurately.
How It Works
Download Test: The test downloads a series of test files from public CDNs to measure your download bandwidth. We use multiple CDN endpoints to get accurate results.
Upload Test: For upload testing, we send data to our servers and measure the time it takes to complete the transfer.
Latency Test: We measure round-trip time by making small requests and calculating the time for a response.
Jitter: Jitter measures the variation in latency over time. Lower jitter means more stable connection quality.
Who Uses This Tool?
Home Users: Check if your ISP is delivering promised speeds
Remote Workers: Verify connection quality for video calls
Gamers: Check latency before gaming sessions
Business: Monitor network performance
Frequently Asked Questions
How accurate is this speed test?
Our test uses industry-standard methodologies and measures your actual connection speed to public CDN servers. Results may vary slightly from other tests due to different server locations and network conditions at test time.
Why is my speed lower than expected?
Several factors affect speed: WiFi signal strength, distance from router, network congestion, ISP throttling, and the server's load. Try restarting your router or moving closer for better results.
Is my data safe during the test?
Yes, all test data is transferred using encrypted HTTPS connections. We don't store any personal information or data from the speed test.
Can I test on mobile devices?
Yes, the speed test works on smartphones and tablets. For most accurate results, close other apps and ensure you're on a stable WiFi connection.
What is a good download speed?
For general browsing and email, 5-10 Mbps is sufficient. HD video streaming requires 10-25 Mbps. 4K streaming and large file downloads need 25+ Mbps. Online gaming needs at least 15 Mbps with low latency.
What is considered high latency?
Latency under 50ms is excellent for gaming and video calls. 50-100ms is good for most activities. Above 100ms may cause noticeable delays in video calls and online gaming.
