Simple checks before an important call

Webcam Tester is a free set of browser-based tools for checking your camera, microphone, and speakers. There is nothing to install and no account to create. You can open a test, allow access when needed, and see what your browser is actually receiving.

The site exists to make pre-call checks quick. A minute here can catch a blocked camera, the wrong microphone, a quiet input, or a missing speaker channel before you join Zoom, Google Meet, or Microsoft Teams.

Every test runs on your device. Camera and microphone media is not uploaded, recorded, or stored. Webcam Tester is an independent, ad-free tool built to give you a clear answer without distractions.
