Camera test
Before an online meeting, check that your webcam shows a picture and what resolution and frame rate it delivers. Video is processed in your browser and never sent anywhere.
Settings
Camera video is only shown in your browser and never sent anywhere. Photos are saved to your device only when you press “Save”.
How to use
- 1
Press “Start camera”
The browser asks for permission to use the camera, so choose “Allow”. If you have more than one camera, you can choose which one to use.
- 2
Check the picture and resolution
The video appears, along with the actual resolution, frame rate and aspect ratio. You can change the resolution in the settings.
- 3
Take a photo to check
Press “Take photo” to show the image at that moment. You can check how fine details come out, and you can also save it.
About the camera test
The resolution shown is the size of the video actually arriving from the camera. The frame rate is the number of video frames counted as arriving in one second. In dark places, the frame rate can drop because the camera uses a longer exposure. The maximum resolution the camera supports is shown when the browser provides that information (Chrome, Edge and others).
By default, the preview is mirrored (the same orientation as a mirror). The other people in an online meeting often see the video unmirrored, so turn mirroring off when checking how text appears. Images shown and saved with “Take photo” are not mirrored.

Frequently asked questions
What should I do if the camera shows nothing?
Check that the browser is allowed to use the camera (you can change this from the icon to the left of the address bar). The camera may show nothing while another app (such as an online meeting app) is using it, so close that app and try again. Also check in the Windows or macOS settings that the browser is allowed to use the camera. On laptops, the camera may be turned off with a camera shutter or a camera key on the keyboard.
Why is the resolution shown lower than the camera's specifications?
Because the default requests 720p (1280×720). Choose “1080p” or “Maximum for this device” under “Resolution” in the settings to raise it to the largest size the camera can deliver. Depending on USB bandwidth and the camera's settings, the frame rate may drop at high resolutions.
Can I check the rear camera of a phone?
Yes. Once the camera starts, the device's cameras are listed under “Camera”, so choose the rear camera.
Is the video sent to a server?
No. The camera video is only shown in your browser and never sent anywhere. Photos you take are only saved to your device when you press “Save”. This page does not send processing statistics either.
