Frequently asked questions

How do I test my webcam?
Open the tool and click the webcam test option. You'll see a live video feed from your camera in real-time. If you see yourself on screen, your webcam is working properly. If the video is dark or missing, check that your browser has permission to access your camera and that no other applications are blocking it.
How can I test my microphone?
Use the mic test feature to record a few seconds of audio and play it back to yourself. You'll hear your own voice, confirming the microphone is picking up sound correctly. If you don't hear anything, verify that your microphone is unmuted, properly plugged in if it's an external device, and that the browser has microphone permissions enabled.
Does this tool store my data or require an account?
No. This is a completely free browser tool that runs locally on your device only. Your webcam feed, microphone recording, and speaker output never leave your computer or get uploaded to any server. No signup, no account, no data collection.
What should I do before a video call or interview?
Use this tool for a quick pre-call check of all three devices—camera, mic, and speakers. Test everything in seconds before joining Zoom, Teams, Google Meet, or any other platform. It typically takes just one minute and can prevent awkward technical problems during important conversations.
