Webcam and Camera Tester.
Check your webcam or phone camera with a live preview, see the resolution and frame rate it reports, and save a test snapshot. Free, no sign-up, and nothing is uploaded.
Live preview
What is a webcam test?
A webcam tester shows the live picture from your camera, along with the resolution and frame rate the browser reports. It helps you check focus, colour and whether the camera works before a video call or recording.
See also the device testers, including Microphone Tester and Screen Tester.
What to check
- Press "Start camera" and allow access. Check that the preview is clear and in focus.
- Compare the resolution with what you expect from your camera. Browsers may choose a lower resolution if the camera can't provide the one requested.
- Take a snapshot and look at it at full size for focus, colour and dust or smudges on the lens.
Low light lowers the frame rate on many cameras, so test in the lighting you will actually use. A camera in use by another app may not start.

Questions.
Why is the frame rate lower than the camera's advertised rate?
Low light, the camera's own settings and the browser can all lower the frame rate. The number shown is what the browser reports for the stream.
Is my camera image uploaded?
No. The preview and snapshot are made in your browser. A snapshot is saved to your device only when you press Save snapshot.
Why does the preview stay blank?
Check that you allowed camera access, that no other app is using the camera, and that the page is loaded over HTTPS. Closing video calls or other camera apps often fixes it.
Why is the preview mirrored?
Most laptop and front phone cameras show a mirror image by default, which feels natural when you look at yourself. Untick Mirror to see the image as the camera captures it.
Can I use this with a USB webcam?
Yes. USB webcams usually appear in the camera list once you allow access. Choose the one you want from the Camera list.
