Why test your device here?

Before an important video call, a job interview, or a gaming session, you want to know your gear works — without installing anything or signing up. Every tool on Test Your Device runs entirely inside your web browser. Your camera feed, microphone audio, and keystrokes never leave your computer.

Pick a test above, allow access when your browser asks, and you'll get an instant result. If something isn't working, each page has a short "how to fix it" guide.
