Webcam test
Check your camera works and see its resolution and frame rate — right in your browser, before a video call.
What this webcam test checks
The test opens your camera through your browser's standard media API and shows the live picture together with the details your camera reports: resolution, frame rate, aspect ratio and an approximate megapixel count. It's the quickest way to confirm the right camera is selected and working before you join a video call.
Reading the results
A sharp, correctly-oriented image at 1280×720 (720p) or higher is fine for almost any meeting; 1920×1080 (1080p) is excellent. A low frame rate or a dark, grainy picture usually points to poor lighting or a busy USB connection rather than a broken camera. If the wrong camera appears, close other apps using it and pick the right device in your browser or system settings.

Frequently asked questions
- Is my video recorded or uploaded?
- No. The camera feed stays on your device and is never sent anywhere — the test runs entirely in your browser.
- Why can't the test see my camera?
- Make sure you allowed camera access, that no other app such as Teams or Zoom is using the camera, and that your browser has permission in your system settings.
- Which browsers work?
- Any modern browser — Chrome, Edge, Firefox or Safari — on desktop or mobile.
- Why is my camera image mirrored?
- Many apps show a mirrored (“selfie”) preview so it feels natural, while other people see you the right way round. This test shows the raw feed from the camera.
- The resolution is lower than my camera supports — why?
- The browser picks a default stream size, and the numbers shown reflect the current stream, not the camera's maximum. Some cameras also drop resolution in low light.
- Can I test an external USB webcam?
- Yes. Plug it in and choose it if your browser asks; if the built-in camera opens instead, switch to the external one in your browser's camera settings.
