About Network Speed Test
Test your internet connection speed with our professional speed test tool. Measure download speed, upload speed, ping, latency, jitter, and packet loss with accurate results. Our tool uses multiple CDN servers worldwide to provide reliable measurements of your network performance.
Unlike basic speed tests, our tool provides comprehensive metrics including real-time speedometer visualization, test history tracking, and detailed connection analytics. Perfect for diagnosing network issues, verifying ISP speeds, testing Wi-Fi performance, or checking connection quality for gaming and streaming.
Frequently Asked Questions
How does the speed test work?
The speed test measures your internet connection by downloading and uploading data to/from CDN servers. Download speed is measured by fetching files from multiple servers and calculating transfer rates. Upload speed is tested by sending data to test endpoints. Ping and latency are measured by sending multiple requests and calculating round-trip times.
Why do I need to test download and upload separately?
Most internet connections are asymmetric, meaning download and upload speeds are different. Download speed affects streaming, browsing, and file downloads. Upload speed is important for video calls, cloud backups, and uploading files. Testing both gives you a complete picture of your connection performance.
What is ping and why does it matter?
Ping (or latency) measures the time it takes for data to travel from your device to a server and back. Lower ping means faster response times, which is crucial for online gaming, video conferencing, and real-time applications. Good ping is typically under 50ms, while anything over 100ms may cause noticeable delays.
What is jitter and packet loss?
Jitter measures variation in ping times - consistent ping times mean low jitter, which is good. Packet loss occurs when data packets fail to reach their destination, causing connection issues. Both metrics are important for stable connections, especially for VoIP, gaming, and video streaming.
Which server should I choose?
Auto mode selects the best server automatically. For most accurate results representing typical internet usage, use Auto mode. Choose specific servers (Cloudflare, jsDelivr, unpkg, Google) if you want to test connection to particular CDN networks. All servers are globally distributed for reliable testing.
How accurate is this speed test?
Our speed test uses industry-standard methods with multiple test iterations to ensure accuracy. However, results can vary based on network congestion, Wi-Fi signal strength, background applications, and server load. For best results, close other applications, use wired connection if possible, and run the test multiple times.
Why are my results different from my ISP's advertised speed?
ISP speeds are typically 'up to' maximum speeds under ideal conditions. Actual speeds vary due to network congestion, distance from exchange, Wi-Fi interference, router quality, and the number of connected devices. Speed tests measure real-world performance, which is often lower than advertised speeds.
Can I save and share my test results?
Yes! After completing a test, you can share results via social media or copy to clipboard. You can also download results as a text file. Test history is automatically saved in your browser (last 10 tests) and displayed as a chart for tracking connection performance over time.
Does this tool work on mobile devices?
Yes, the speed test is fully responsive and works on smartphones and tablets. However, mobile results may be lower than desktop due to Wi-Fi signal strength, cellular connection quality, or device processing power. For most accurate results on mobile, ensure strong Wi-Fi signal and close background apps.
What's the difference between this and other speed test tools?
Our tool provides comprehensive metrics (download, upload, ping, jitter, packet loss) with visual speedometer, real-time progress tracking, test history charts, and multiple server options. It's completely free, ad-free, requires no registration, and respects your privacy. All tests run client-side in your browser.
