Internet Speed Test
Free browser-based internet speed test. Measure download speed, upload speed, ping, and jitter. No app or plugin required. Works on any device with a modern browser.
How to Use the Internet Speed Test
Click Start Test to begin measuring your internet connection. The test runs four phases automatically: ping, jitter, download speed, and upload speed. A real-time speedometer gauge and live speed graph update throughout each phase. When the test completes, a results summary shows quality ratings for gaming, video calls, 4K streaming, and remote work. Your results are saved locally so you can compare speeds over time. Click Test Again to re-run at any time.
About This Tool
This tool measures your internet connection speed directly from your browser — no plugins, apps, or downloads required. It uses three lightweight API endpoints hosted on the same server: a ping endpoint for latency, a download endpoint that streams random data, and an upload endpoint that receives and discards data. Download speed is measured using the Fetch Streams API to track bytes received in real time. Upload speed uses XMLHttpRequest for accurate upload progress tracking. The test adapts its payload size based on an initial probe to balance accuracy and speed. All measurements are displayed in Mbps (megabits per second) using a logarithmic-scale speedometer gauge. Results include quality ratings based on standard thresholds for common use cases. No personal data is collected — all processing happens in your browser.

Frequently Asked Questions
Why is my speed test result different from my ISP's advertised speed?
ISPs advertise 'up to' speeds under ideal conditions. Real-world speeds vary based on network congestion, Wi-Fi signal strength, distance from the router, device capabilities, and the number of devices sharing the connection. Wired Ethernet connections typically achieve higher, more consistent speeds than Wi-Fi.
What is the difference between download and upload speed?
Download speed measures how fast data travels from the internet to your device — affecting streaming, browsing, and file downloads. Upload speed measures how fast data travels from your device to the internet — affecting video calls, file uploads, and live streaming. Most home connections have faster download than upload speeds.
What is ping and jitter?
Ping (latency) is the round-trip time for a small data packet to travel from your device to the server and back, measured in milliseconds. Lower ping means a more responsive connection. Jitter is the variation in ping times — high jitter causes inconsistent performance, especially noticeable in video calls and online gaming.
How can I improve my internet speed?
Use a wired Ethernet connection instead of Wi-Fi. Move closer to your router or use a mesh network. Close bandwidth-heavy applications. Restart your router. Check for firmware updates. Consider upgrading your internet plan. Run tests at different times — congestion during peak hours can significantly reduce speeds.
