Internet Speed Test
Measure ping, download and upload speeds from your browser. This client-side test provides quick estimates — see the notes below for accuracy and CORS limitations.
Run a Speed Test
Default uses a public test file. You can provide your own test file URL (larger files give more accurate download estimates).
If the endpoint allows cross-origin POSTs, upload test will run; otherwise upload will show blocked.
Test runs: Ping → Download → Upload
Important: Browser-based speed tests are best-effort. They depend on the test file server, network path, and whether remote servers allow cross-origin requests (CORS). For highly accurate measurements use dedicated server-side endpoints or commercial speed test services.
