# How to test your webcam before a call

Updated 2026-11-09

To test your webcam online, press start, allow camera access, and look at the live preview. Webcam Test shows the camera name, the resolution and the frame rate your browser is receiving. You can switch between cameras and save a snapshot. The picture stays in your tab, and the camera turns off when you stop.

## Test your webcam in four steps

The camera starts only after you press the button, never when the page loads.

1. Press Start camera and allow camera access when the browser asks.
2. Check the preview, then read the camera name, Resolution and Frame rate below it.
3. Open Camera to test to switch to another camera if you have more than one.
4. Press Take snapshot to save a PNG, and press Stop camera when you are done.

## What resolution and frame rate mean

Resolution is the picture size in pixels. A reading of 1920 by 1080 is called 1080p. Frame rate is how many pictures arrive each second. Video calls feel smooth at around 30, and a low number looks jerky.

These are values the browser actually received, not the numbers printed on the box.

## Why the numbers can be lower than expected

The browser asks the camera for a default size, so it may not run at its maximum. Another app holding the camera, a USB port with limited bandwidth, or a dim room can all lower the size or the frame rate. Close other apps that use the camera and test again.

## If the preview stays black or an error appears

A message that no camera was found means none is connected or another app has it. A message that access is blocked means permission was denied. Open the site settings in the address bar, allow the camera, and press Start camera again.

A black preview with no message often points to a privacy shutter or a physical switch on the laptop.

## Check light and framing with a snapshot

A snapshot is a PNG at the same size as the live picture. Save one to judge how your face is lit and where you sit in the frame.

## Questions

### Does the test record or send my video?

No. Nothing is recorded. A snapshot is saved only when you press the snapshot button and download the file.

### Which camera does it test if I have two?

Use the Camera to test menu to pick between the built-in camera and an external one.

### My camera works here but not in my meeting app. Why?

The meeting app may have its own permission or be set to a different camera. Check the app's video settings and close any other app that is using the camera.
