Camera Test — Free Online Webcam Test Tool
What Is a Camera Test?
A camera test is a quick check to confirm your webcam is working correctly. Before a video call, job interview, live stream, or online class, running a camera test online takes only seconds and prevents embarrassing technical problems.
Camera Test (cameratest.vn) lets you test your camera instantly in any browser — no download, no sign-up, no plugins.
How to Camera Test Online
- Open this page — your browser will request camera permission automatically.
- Click Allow — grant permission when the browser prompts you.
- Check the preview — your live webcam feed appears immediately.
- Verify image quality — confirm the picture is sharp, bright, and correctly oriented.
- Take a photo — click Take Photo to capture a snapshot.
- Download — save the snapshot as a JPEG file instantly.
If the live preview shows your face clearly, your camera is working.
Why Run a Camera Test?
- Job interviews & meetings — prevent a black screen at the worst moment.
- Streaming & recording — verify framing, lighting, and focus before you go live.
- After OS updates — system updates can silently reset camera permissions.
- New devices — USB webcams, laptops, and phones behave differently.
- Troubleshooting — isolate whether the issue is hardware, software, or permissions.

Frequently Asked Questions
Does the camera test work on phones?
Yes. On Android and iOS, the tool uses your front camera by default. Use Chrome or Safari for best results.
Is my video uploaded anywhere?
No. All processing happens locally in your browser. Nothing is sent to our servers.
Which browsers are supported?
Chrome, Firefox, Edge, and Safari (iOS 14.3+). Internet Explorer is not supported.
Can I test an external USB webcam?
Yes. Connect your USB webcam before opening the page. If multiple cameras exist, the browser may choose one automatically; you can switch in your OS settings.
Why is the preview mirrored?
The mirror effect makes the preview feel natural, like looking in a mirror. Downloaded photos are also mirrored to match exactly what you see.
