Test your internet connection online for free. Check download speed, upload speed, ping, jitter, public IP, and connection information on mobile and desktop.
Internet Speed Test is a browser-based tool that measures your download speed, upload speed, ping, and jitter to help you understand the performance of your internet connection.
The test sends and receives data between your browser and a speed test server, then calculates the transfer speed and connection latency based on the measured results.
Download speed measures how quickly data can be transferred from the internet to your device. Higher download speeds are generally better for streaming, downloading files, browsing, and other online activities.
Upload speed measures how quickly data can be sent from your device to the internet. It is important for video calls, uploading files, cloud backups, and sharing content online.
Ping, or latency, measures how long it takes for a request to travel to a server and return. Lower ping generally means a more responsive internet connection.
Jitter measures how much your connection latency changes during the test. Lower jitter generally indicates a more stable connection, which is especially useful for online gaming and video calls.
The test provides a browser-based estimate of your connection performance. Results can vary depending on Wi-Fi signal strength, network congestion, device performance, browser limitations, VPNs, and other network activity.
Different speed tests may use different servers, testing methods, data sizes, and measurement techniques. Results can therefore vary even when testing the same internet connection.
Yes. The Internet Speed Test is designed to work on smartphones, tablets, laptops, and desktop computers using a modern web browser.
No. The Internet Speed Test runs directly in your web browser, so no app or software installation is required.
Yes. The speed test transfers data to measure download and upload performance. The amount of data used depends on the test configuration and your connection.
Internet speed can fluctuate because of Wi-Fi conditions, network congestion, server load, background downloads, other connected devices, and temporary changes in your connection.
Yes. No account or registration is required to run the Internet Speed Test.
Yes. The tool can display your public IP address along with available connection information such as IP version, browser, device type, and network estimates.
Recent test results are stored locally in your browser on your device. They are not stored in an online account.
For more consistent results, use a wired connection when possible, stop other downloads and uploads, close unnecessary applications, disable VPNs if appropriate, and run the test more than once.
Yes. You can use the Internet Speed Test online for free without installing software or creating an account.
