See what your camera sees
A live preview shows your picture the way a video call would, mirrored by default. Optional guides mark the rule-of-thirds lines and a head-and-shoulders oval so you can centre yourself and leave the right space above your head.
Real resolution and frame rate
The readout reports the resolution the camera is actually delivering, its aspect ratio and megapixels, and a frame rate counted from the frames your browser displays. Request HD, Full HD or 4K to see which modes the camera supports.
Lighting check and snapshot
A lighting readout tells you when the picture is dark, a little dim, good or overexposed, and warns about a black picture from a closed lens cover. Take a full-resolution PNG snapshot to compare cameras or positions.

What people use this tool for
- Check your framing, background and lighting a few minutes before an interview or online class.
- Confirm that a new USB webcam really delivers the Full HD or 4K mode on its box.
- Find out whether a black picture comes from a privacy shutter, a permission setting or another app.
- Compare a laptop camera with an external one by taking a snapshot from each.
Frequently Asked Questions
How do I test my webcam online?
Select Start camera and allow camera access when your browser asks. Your picture appears in the preview within a second or two, and the readout shows the resolution, frame rate and lighting. If you see yourself, the camera and the browser are working.
My camera does not start. What should I check?
Close other apps that may be using the camera, such as Zoom, Teams or a camera app, because many cameras serve one app at a time. Check for a physical privacy shutter or a camera-off key on the keyboard. Then confirm the browser has camera permission, both for this site in the address bar and in your system privacy settings.
Why is the picture black?
A black picture with a working camera light usually means a closed privacy shutter, a lens cover or a camera that another app is holding. The Lighting readout says Black picture when it detects this. Open the shutter, close other camera apps, or choose a different camera from the Camera list if your device has more than one.
Why is the resolution lower than I asked for?
The Requested resolution setting is a request, not a command. The camera answers with the closest mode it supports, so a 720p webcam asked for 4K still delivers 1280 × 720. The message under the preview tells you when the delivered size differs from the request. Low light and USB hubs can also make some cameras fall back to a lower mode.
Why is my preview mirrored?
Video call apps show you a mirrored self-view because it feels like looking in a mirror, while other people see you unmirrored. This preview does the same. Clear Mirror preview to see the picture as others receive it, which is useful when you hold up text. A snapshot is saved the way the preview shows it.
Is my video recorded or uploaded?
No. The camera picture is drawn straight to your screen and never leaves your browser. A snapshot is created on your device and stays there unless you download it. The camera switches off when you select Stop camera, hide the tab or leave the page.
How is the frame rate measured?
In browsers that support it, the tool counts the frames actually presented each second, so the number reflects what you would see in a call. A camera often lowers its frame rate in dim light to gather more light per frame, which is why adding light can make motion look smoother. Where frame counting is unavailable, the readout shows the rate the camera reports.
How can I look better on a video call?
Put your main light in front of you rather than behind, and raise the camera to eye level. Turn on Framing guides, keep your eyes near the upper line and leave a little space above your head. Aim for a Lighting readout of Good; a bright window behind you makes the camera darken your face.
