Online Webcam Test
See exactly what your camera sees, before anyone else does.
This webcam test shows you your camera's live picture right in the browser. Click start, allow camera access, and you see exactly what the other side of your next video call will see: whether the camera works at all, and just as usefully, how you are framed and lit.
Run it before the meetings that matter, a job interview on Zoom, a client call on Teams, an online exam. It catches the practical failures early: a privacy shutter still closed, the wrong camera selected when an external one is plugged in, a driver that needs a reconnect, or another app holding the camera hostage. And the preview doubles as a mirror check for the fixable stuff: backlight from a window, a laptop camera staring up your nose, clutter behind you.
Like every check on this site, it is private by design. The video renders locally in your browser and is never recorded, captured or sent anywhere; there is no server on the other end. Close the tab and the camera light goes off. The browser permission prompt you will see is standard for any camera access, and here it exists only to show you your own preview.
How to test your webcam
- Click Start Webcam Test.
- When the browser asks for camera permission, click Allow. The feed stays on your device; nothing is recorded.
- If you have more than one camera, choose the right one from the device dropdown.
- Check the live preview: is the image sharp, well lit and facing the right way?
- Adjust before the real call: face a light source, raise the camera to eye level, tidy the frame.
- Close the page when finished; that releases the camera and the indicator light turns off.
Black screen? Run down this list
Most webcam failures are one of five things. A closed privacy shutter or cover sticker, easy to forget on office laptops. A denied browser permission: click the padlock in the address bar, reset the camera permission and reload. The wrong device selected, common with external webcams and virtual cameras from streaming software. Another app already using the camera, since only one app gets it at a time; close Zoom, Teams or OBS and retry. Or, on Windows and macOS, the system privacy setting that blocks browsers from the camera entirely.
If the preview works here but an app shows nothing, your camera is proven good; point the app at the same device in its video settings. That one fact, camera fine versus camera broken, is exactly what this test is for.
Nothing is recorded: how the private webcam test works
This is the fear worth answering head-on: your video is not recorded, screenshotted or uploaded. When you allow access, the browser streams the camera straight to a preview element on the page and nothing more. There is no server receiving it, no file being written and no copy stored anywhere; the picture exists only on your screen, in the moment.
The feed lives entirely on your device and stops the instant you close the tab, which is why the camera's indicator light goes out when you leave. The whole point of doing this in the browser is that you can confirm your camera works without ever trusting a stranger's server with your face.
What to look for in the preview
Start with the basics: is the image sharp, or soft and hazy? A blurry picture often just means a smudged lens, so a quick wipe with a soft cloth can transform it. Check the exposure too; if you are a dark silhouette, light is behind you, and if you are blown out and pale, there is too much light hitting the lens directly.
Then read the framing as your callers will see it. Your eyes should sit around the upper third of the frame, not floating in the middle with headroom to spare or cut off at the top. Glance at the background for clutter or anything you would rather not broadcast. The preview is the one chance to fix all of this before anyone else is looking.
Managing camera permissions and the indicator light
The permission prompt is your browser protecting you: no page can open the camera without a clear yes from you, and this test asks only so it can show you your own preview. If you blocked it before, the browser remembers, so click the padlock or site-settings icon in the address bar, reset the camera permission for the site and reload.
Watch the hardware indicator light while you are here. It should come on when the preview starts and, importantly, go off the moment you close the page. That light is a genuine privacy signal worth trusting across all your apps: if it is on when you expect no camera to be running, something has the camera open, and if it is off, nothing is watching. Above the browser, remember the Windows and macOS system camera privacy switch can block every website at once.
Look your best on camera
Two changes do most of the work: light and height. Face a window or a lamp so the light falls on your face rather than glaring from behind you, which is the single most common reason people look like a shadow on calls. Then raise the camera to roughly eye level, propping a laptop on a stand or a stack of books, so it stops filming up your nose and gives a natural, level angle.
After that, tidy what is behind you and leave a little space above your head rather than filling the frame with forehead. Use the live preview to judge all of it before you join, nudging the lamp, the laptop and your posture until the picture looks the way you want other people to see you.
Real moments this saves you
The classic use is the minute before something important: a job interview on Zoom, a client call on Teams, or an online exam with proctoring, where a dead camera or a closed shutter turns into a scramble at the worst possible time. Checking here first means you walk in knowing the camera works and that you are framed and lit the way you intend.
It is equally useful for setup and troubleshooting: confirming a new external webcam before you rely on it, choosing between a built-in and a plug-in camera, checking a virtual camera from streaming software is passing through, or simply proving your hardware is fine when an app stubbornly shows black. In every case, the private preview answers the only question that matters, is the camera working.

A camera check is only half of a call. The mic test shows a live level meter for your microphone the same way this shows your camera, live and only on your device, so pair the two to confirm both picture and sound before you join.
Rounding out a desk setup, the keyboard tester verifies every key registers cleanly. As with this webcam test, both run entirely in your browser, are free and unlimited, and record nothing, so you can run a complete pre-meeting check in under a minute without downloading a thing.
Frequently asked questions
Is my video recorded or uploaded?
No. The preview is rendered locally in your browser and never leaves your device. Nothing is recorded, screenshotted or transmitted, and camera access ends the moment you close the page.
Is the webcam test free?
Yes, free and unlimited with no sign-up. Make it a 30-second habit before important calls.
Why do I get a black screen?
Usually a closed privacy shutter, a blocked browser permission, the wrong camera selected, or another app holding the camera. Check the shutter, reset the permission from the address-bar padlock, try each device in the dropdown, and close other video apps.
The camera works here but not in Zoom or Teams. What now?
This test just proved the camera and system permissions are fine. Open the app's video settings and select the same camera; also check the app itself has OS-level camera permission and that no other program is using the device.
How do I look better on camera?
Light and height do most of the work. Face a window or lamp so light hits your face rather than your back, and raise the camera to eye level; a laptop on a stand or a stack of books ends the up-the-nose angle. Use the preview to check both before joining.
Why does the image look mirrored?
Previews are usually mirrored so they behave like a mirror, which feels natural to you. Meeting apps send the unmirrored image to other people, so text on a shirt reads correctly to them even if it looks flipped in your preview.
Does it work on phones and tablets?
Yes. On iPhone and Android you also get a front/back camera switch, so you can check either lens before a mobile video call.
