Webcam Tester
See yourself as your camera sees you. Check that the webcam works, what resolution and frame rate it really delivers, and how the lighting looks — before the call starts.
At a glance
- Tests a webcam in your browser: press the button, allow access, and the live picture appears with its resolution and frame rate.
- Reports the real resolution (for example 1920 × 1080, Full HD), megapixels, aspect ratio and the frames per second actually arriving — measured, not just what the camera claims.
- Asks the camera for its best mode, so a Full HD webcam is not tested at the 640 × 480 that browsers often start with.
- Judges the lighting — too dark, well lit or washed out — and warns when the picture is black because of a lens cover.
- Takes a photo (PNG at full resolution) and records a clip of up to 30 seconds to play back and download.
- Lets you choose between cameras, try each standard resolution, mirror the preview, show grid lines and go full screen.
- The picture stays on your device. Nothing is uploaded or stored.

Preview yourself mirrored like a video call, with rule-of-thirds lines to frame the shot.

No sign-up, no upload. The video never leaves your browser.
Webcam resolutions
The resolution is the number of pixels in each frame. More pixels give a sharper picture, as long as there is enough light.
| Name | Pixels | Megapixels | Shape |
|---|---|---|---|
| 4K UHD | 3840 × 2160 | 8.3 MP | 16:9 |
| QHD 1440p | 2560 × 1440 | 3.7 MP | 16:9 |
| Full HD 1080p | 1920 × 1080 | 2.1 MP | 16:9 |
| HD 720p | 1280 × 720 | 0.9 MP | 16:9 |
| VGA 480p | 640 × 480 | 0.3 MP | 4:3 |
| QVGA 240p | 320 × 240 | 0.1 MP | 4:3 |
What is good enough for video calls?
- Full HD (1080p) at 24 fps or more — excellent. More than a call needs; right for streaming and recording.
- HD (720p) at 20 fps or more — good. What most video calls actually send.
- 480p — basic. Fine on a phone-sized window, soft on a large screen.
- Below 12 frames a second the picture looks jerky. Low frame rates are usually caused by poor light: the camera slows down to gather more of it.
Webcam not working? Check these
- Permission — click the icon at the left of the address bar and set Camera to Allow, then try again.
- Privacy shutter — many laptops have a sliding cover over the lens or a camera key (often F8 or F10). A black picture usually means it is closed.
- Another app — only one app can use most cameras at a time. Close Zoom, Teams, Meet or the Camera app.
- Privacy settings — in Windows and macOS, switch on camera access for your browser under Privacy & security → Camera.
- The right camera — choose the camera you want from the list; a virtual camera from another program may have been picked.
- The cable — for a USB webcam, unplug it and plug it into another port, directly rather than through a hub.
Look better on camera
- Face the light. A window or lamp in front of you beats one behind you.
- Raise the camera to eye level and sit an arm’s length away.
- Wipe the lens — a fingerprint makes the whole picture hazy.
- Use the grid: put your eyes on the upper line.
