About the Webcam Test
A webcam test takes ten seconds and saves the awkward opening of a video call. It answers three separate questions at once: does the camera turn on at all, which camera is your browser actually using, and what picture is the other side going to see.
The numbers underneath the preview are worth a glance. Resolution tells you whether you are getting the sharp mode your camera is capable of or a reduced one. The frame rate is measured from frames that actually appear rather than read from the camera's own claim, so it reflects what viewers really see — and it drops noticeably in dim light, because the sensor holds each frame open longer to gather light.
If the picture is black while the indicator light is on, the usual causes are a privacy shutter still closed, a lens cover, or another application holding the camera. If nothing happens at all, the browser is probably still waiting for permission.
Your video is displayed in your browser and nowhere else. Nothing is recorded and nothing is uploaded.
How to test your webcam
- Press the start button and allow camera access when your browser asks.
- Check the preview. If it stays black, look for a privacy shutter or lens cover.
- Read the resolution and frame rate below the picture. If the frame rate looks low, the usual cause is dim light rather than a fault — the sensor lengthens each exposure to compensate.
- If you have more than one camera, switch between them with the selector.
- The preview starts mirrored, the way most video apps show it. Press the mirror button to see yourself unmirrored, the way others see you — mirroring only ever affects a preview, never the picture a call sends.
- Press Stop when you are done, so the camera is released. The indicator light beside the lens should go out.
Frequently asked questions
The light comes on but the picture is black.
Almost always a physical cover: many laptops have a sliding privacy shutter, and external webcams often ship with a cap. If there is no cover, another application may be holding the webcam and supplying an empty frame — close any video-call software and try again.
Why is my resolution lower than my camera's specification?
Browsers request a reasonable default rather than your webcam’s maximum, and cameras drop to a lower mode in poor light or when bandwidth-saving settings are on. The figure shown here is what you are actually getting, which is the number that matters on a call.
My frame rate is much lower than 30. Is the camera faulty?
Usually not. In dim light a webcam sensor exposes each frame for longer, which halves or quarters the frame rate to keep the picture bright. Turn on a lamp and watch the number rise. A slow computer under heavy load can also reduce it.
Why does my picture look mirrored?
Because that is what people expect when they see themselves — it matches a bathroom mirror. Other participants on a call see the unmirrored view. Use the mirror button to switch and check how text or a logo behind you actually reads to them.
The picture shows up here but my meeting app sees nothing.
Then your webcam and its driver are both fine. The app is either selecting a different device or has been denied camera permission at the system level. Check the app’s video settings and your operating system’s privacy settings for camera access.
Is any video recorded or uploaded?
No. The webcam stream is displayed inside your browser and never leaves your device. There is no recording feature here and nothing is sent to any server.
Is the Webcam Test free, and do I need to install anything?
Free, with no account, no email and nothing to download. Your browser asks for camera permission once, the preview starts, and revoking the permission afterwards takes one click in the address bar.
Does this test my microphone too?
No — it asks for the camera only. The permission request never includes audio, so this page cannot hear anything at all, and a clear picture here tells you nothing about whether people will hear you on a call. That is also why nothing from your microphone could be recorded here: it is never opened. If you are checking before a meeting, run the microphone test as well, and the speaker test if you want to confirm you can hear them.
Why not just open the camera app on my computer?
Because that proves a different thing. The camera app shows that the hardware and its driver work; it says nothing about whether your browser can reach the camera — and video calls, interviews and online exams almost all happen inside a browser. That gap is where most of the failures live.
