Controls and results explained
Start test and permission
Start camera test requests browser permission and begins the private preview. If the prompt does not appear, check this site's camera permission, the operating-system privacy setting, and any physical webcam shutter.
Mirrored and unmirrored preview
Mirrored matches the self-view used by most call apps and makes movement feel natural. Unmirrored shows the orientation other participants and saved captures normally receive; changing it does not change camera quality.
Resolution and aspect ratio
Resolution is the width and height delivered by the active video track, not merely the camera's advertised maximum. Aspect ratio identifies the picture shape, such as 16:9 or 4:3.
Reported and measured frame rate
The reported fps is the camera track setting; measured fps counts frames actually reaching the preview. A lower measured rate can point to dim lighting, a busy computer, bandwidth-saving drivers, or another app using the camera.
Facing mode
Facing indicates whether a mobile device reports a user-facing or environment-facing camera. Some desktop webcams and browsers do not expose this value, which is normal.
Camera selector
Use the Camera device menu to switch among all cameras exposed by the browser. Device names usually become visible only after camera permission is granted.
Snapshot and download
Take snapshot freezes one full-size frame for close inspection. Download saves that frame as a PNG; the live stream and snapshot remain on this device unless you choose to save or share the file.
Camera report and stop
Copy or download the text report when requesting support. Stop test releases the camera and switches off the active camera indicator.
Reported versus delivered
The resolution and frame rate come from the video track itself. Many cameras drop their frame rate in dim light, so the measured rate can sit below the advertised one.
The mirror only affects you
The preview is mirrored by default because that is how video apps show your own image. People on a call see the unmirrored view, which you can check with the mirror toggle.
Nothing leaves your device
The preview and any snapshot are held in this browser tab. Closing or refreshing the page discards them.
Practical tips for better results
- A camera indicator light that stays on after you stop the test usually means another app is still using the camera.
- If the preview is black, check for a physical privacy shutter and that no other app has the camera open.
- Camera names only appear after you allow access at least once.
Frequently asked questions
Why is the preview black or frozen?
Most often another application still holds the camera, or a privacy shutter is closed. Close other video apps, check the shutter, then start the test again.
Why is my resolution lower than the camera supports?
The browser negotiates a mode with the camera and can settle on a lower one in poor light or when another constraint applies. The reported figures are what this browser is really receiving.
Are my video or snapshots uploaded?
No. Everything happens in this browser tab and is discarded when you leave the page.
