Webcam Test — Check Your Camera Online

Check that your webcam works, see the resolution it delivers and take a test photo.

To test your webcam, press start and allow camera access — the live preview appears immediately along with the resolution, frame rate and device name your camera actually reports. You can switch between cameras, request a different resolution, take a still photo and record a clip. Nothing is uploaded; the stream stays in the page.

Frequently asked questions

Why is my camera showing a black screen?

Almost always another application is holding it. Video-call software takes an exclusive lock on many systems, and the browser then gets a stream with no frames rather than an error. Quit the other app entirely — minimising it is not enough — and restart the test.

Why does my camera look mirrored?

Browsers show a self-view mirrored because that is what people expect from a mirror, and video-call apps do the same. What is recorded and what other people see is not mirrored — only your own preview is.

Why can I not get 1080p from a 4K webcam?

Constraints are a request. A camera negotiates the closest mode it supports at a frame rate it can sustain over the connection, and USB 2.0 bandwidth in particular forces a drop. The panel shows the resolution you actually received rather than the one you asked for.

Does this work on a phone?

Yes, on both front and rear cameras. The device list is populated once you grant permission — browsers hide device labels before that, so the picker looks empty until the first successful start.

How to use the camera test

  1. 1Press "Start camera" and allow access when the browser asks.
  2. 2Check the preview and the reported resolution.
  3. 3Switch cameras or request a different resolution if needed.
  4. 4Take a photo or record a clip to verify the output.
