Webcam Tester

Free Online Webcam Tester with Live Preview and Recording

What is this webcam tester tool?

This webcam tester is a free browser-based tool that lets you check if your camera is working correctly. It displays a real-time video preview, allows you to select between multiple camera devices, and includes a record-and-playback feature to test both video and audio capture. No software installation or account registration required.

How do I test my webcam online?

Click the "Allow Camera Access" button and grant permission when your browser prompts you. Once connected, you'll see a live video feed from your camera immediately. The preview shows exactly what your camera captures, helping you verify the image quality, focus, lighting, and framing before video calls or recordings.

Why is my camera not working in the browser?

Common reasons include blocked browser permissions, incorrect device selection, or the camera being used by another application. Check your browser's address bar for a blocked camera icon and click it to allow access. If you have multiple cameras, use the device selector dropdown to switch between them. Close other applications that might be using your camera, such as video conferencing software or other browser tabs. If you don't have a webcam, you can use our Microphone-Only Tester Tool instead.

Can I record video to test my webcam quality?

Yes. After granting camera access, click "Start Recording" to capture a test clip. The recording captures both video and audio from your camera and microphone. When you stop recording, a playback card appears below the live preview where you can watch your recording and assess the video quality, check for audio sync issues, or verify your camera settings before important meetings.

Is my video data sent to a server?

No. All video processing happens locally in your browser. Your camera input never leaves your device, and recordings are stored temporarily in browser memory until you close the page or record a new clip. This makes the tool suitable for testing cameras before confidential video calls or recordings.

How do I switch between multiple cameras?

If you have multiple video input devices connected (built-in laptop camera, USB webcam, external camera), use the dropdown selector at the top of the tool to choose which one to test. The tool automatically detects available devices after you grant camera permission. Selecting a different device reconnects the video stream and updates the live preview to show the new camera feed.

Can I use this tool to test my webcam before a video call?

Yes, this tool is ideal for pre-call camera checks. Test your webcam a few minutes before joining a meeting to ensure it's working, properly positioned, and producing good image quality. Use the record-and-playback feature to verify your lighting, check that your audio is being captured alongside video, and confirm the correct camera is selected if you have multiple devices.

How do I troubleshoot common webcam issues?

If your camera shows no video or displays an error, try these steps: refresh the page and grant permission again, check that no other applications are using your camera, try a different USB port for external webcams, restart your browser, or restart your computer if the camera is unresponsive. The tool's error messages provide specific guidance for permission denials, device not found, and device busy scenarios.
