Webcam Test
Test your webcam online with a live browser preview, camera selection, resolution, frame-rate details, mirror control, and a framing grid.
Camera access starts only when you choose Start webcam test. Webcam video is displayed in this browser page and is not uploaded, recorded, or saved by the Webcam Test.

What this webcam test checks
This test verifies whether your browser can open a video-input track and show the current camera stream. It exposes browser-observed details about the active stream without pretending to certify the camera hardware.
Choose the right camera
When the browser exposes multiple video inputs, switch between built-in, USB, front, or rear cameras without discarding a working stream if the replacement fails.
Read stream details
Review the active resolution, aspect ratio, browser-reported frame rate, and observed presented frame rate when the browser supports it.
How to test your webcam
- Choose Start webcam test.
- Allow camera access in your browser.
- Confirm that the live preview appears and matches the camera you intended to use.
- If more than one camera is available, use the Camera selector to switch inputs.
- Review resolution and FPS details, then choose Stop camera when finished.
Resolution and aspect ratio
Resolution describes the width and height of the video stream currently delivered to this page, such as 1280 × 720. Aspect ratio reduces those dimensions to a familiar relationship such as 16:9 or 4:3. These values describe the active browser stream and do not prove the camera's maximum hardware resolution.
Reported FPS and Presented FPS are different
Reported FPS is the frame rate reported by the active browser video track when available. Presented FPS is estimated from video frames actually presented to this page when the browser supports video-frame callbacks. Display refresh, browser scheduling, stream negotiation, and device behavior can make the two values differ.
Why camera names may appear only after permission
Browsers can limit device labels before camera permission has been granted. The selector is therefore populated after the test starts rather than inventing camera names before the browser exposes them.
Mirror preview and framing grid
Mirror preview flips only the picture shown on this page, which can feel more natural for a self-view. It does not modify the MediaStream or tell another application to mirror your camera. The grid is only a visual framing aid.
What this test does not measure
Webcam Test does not assign a camera-quality score, certify color accuracy or lens sharpness, discover a camera's guaranteed maximum specification, record video, take snapshots, test your microphone, or certify that Zoom, Teams, Meet, Discord, or another application is configured correctly.
Scenario: laptop plus USB webcam. Start the built-in camera, then choose the USB camera from the selector. The preview, device label, and current stream details should update only after the replacement camera starts successfully.
Scenario: phone or tablet. Start the camera and, when the browser exposes multiple video inputs, choose another available camera. Facing-mode labels vary by browser and device, so this test reports them only when the active track supplies them.
Privacy boundary
Webcam Test requests video only and does not request microphone audio. Camera frames stay in the browser's media pipeline for this page and are not uploaded, recorded, or saved by the Webcam Test. Mycelgrid's website-level services, including advertising when enabled, are separate from camera video and are covered by the Mycelgrid Privacy Policy.
Troubleshooting a black or unavailable camera
Check browser camera permission, operating-system privacy settings, a hardware privacy shutter, and whether another application is using or blocking the camera. If the wrong camera opens, use the Camera selector after permission has been granted.

Why does Webcam Test need camera permission?
Browsers require explicit permission before a web page can receive a camera stream. This test requests access only after you choose Start webcam test.
Is my webcam video uploaded?
No. Webcam video is displayed in the current browser page and is not uploaded, recorded, or saved by the Webcam Test.
Why do camera names appear only after I allow access?
Browsers can restrict device labels until camera permission has been granted. After access begins, the browser can expose additional video-input names for the selector.
Why is my camera black?
A black picture can come from a hardware privacy shutter, poor lighting, another app holding the camera, browser or operating-system privacy controls, a disconnected device, or a camera that did not start correctly.
Why can my camera work here but not in another app?
Each application can have its own selected camera, permission state, operating-system access, and video settings. This page confirms what this browser receives; it cannot inspect another application's configuration.
What does webcam resolution mean?
It is the width and height of the active video stream currently delivered to this page, not necessarily the camera's highest supported hardware mode.
Why can Reported FPS and Presented FPS differ?
Reported FPS comes from browser track settings. Presented FPS is estimated from frames this page observes being presented, so browser scheduling, display timing, and video delivery can affect it.
Does mirror mode change what other apps receive?
No. Mirror preview is a visual transformation applied only to this page's video element.
Does this test use my microphone?
No. Every camera request from this app explicitly requests video with microphone audio disabled.
