How do I test whether my webcam works?

Press Start camera and allow access for this site. A visible picture confirms that the selected input is delivering video to this browser page. Check framing and lighting, then read the device name and actual picture dimensions. Auto leaves size selection to the browser; 720p and 1080p request preferred sizes. Stop releases this page's tracks. This does not certify camera health, sharpness or performance in every application.

Can I test a laptop camera or an external USB webcam, including Logitech?

Yes, when the system and browser expose it as a camera input. This includes built-in laptop cameras on Dell, HP or Lenovo machines and USB webcams such as Logitech, NexiGo or Trust devices. Connect or enable the camera, open the page and choose it from Camera after permission. Labels may be hidden before access is granted. Check a privacy shutter, disabled input or loose USB connection if no picture appears. The page has no manufacturer driver, firmware or model-specific diagnostic.

The browser blocked my camera. How do I allow it again?

A refusal means access was not granted to this page; it does not prove that the hardware is healthy or faulty. Check the site's camera permission in Chrome, Edge, Firefox or Safari, then try again. In Chrome or Edge, use Site settings, Camera. Firefox lets you clear blocked access from the address-bar permission panel. Safari uses Settings for This Website, Camera. On Windows 10 or 11, check Settings, Privacy or Privacy & security, Camera, including access for desktop apps. On macOS, check System Settings, Privacy & Security, Camera for the browser. The panel shows browser-specific steps. Restricted policies or extensions can also prevent access.

Why is the resolution lower than 1080p or full HD?

A resolution button requests an ideal size, not an exact hardware mode. A camera may return a different size because of its available modes, driver, virtual-camera source or browser. The row reports track settings and updates to the video element's decoded dimensions when available. A requested 1920 by 1080 does not prove that full HD arrived. There is no automatic sharpness, color accuracy or image-quality score.

How is webcam FPS measured?

Where available, the page measures changes in the presented-frame counter over a recent interval. Otherwise it uses the browser's video playback-quality frame counter after subtracting dropped frames. Playback time is never counted as new frames. Until a usable counter interval is available, the row labels the negotiated rate separately or says no measured rate yet. Frame-rate changes can reflect lighting, device settings, dropped presentation or browser load; they do not diagnose a faulty camera.

How do I use the fullscreen or mirror webcam test?

Start the camera, then choose Fullscreen preview in the Picture panel. Exit from that button or your browser's fullscreen control. Some browsers and embedded views do not expose fullscreen; the tool explains that refusal and the normal preview continues. Mirror On flips only the local picture. Mirror Off shows an unflipped preview. Neither changes resolution or FPS, and neither determines what another application transmits.

Can I test my webcam microphone at the same time?

Yes. Enable Include microphone or use the camera and microphone subpage, then start both inputs. Speak and watch the RMS and peak meter. A webcam's built-in microphone may appear as a separate audio input, so select it from Microphone rather than assuming it matches the selected camera. Camera and audio permissions are requested separately. If one is refused, the other can continue. Audio is not sent to speakers or recorded here; the separate Mic Test supports a recording and playback workflow.

Does this webcam test work on Windows, Mac, Linux or Android?

Use a current browser on a secure connection that exposes camera capture. The same preview can test inputs available to that browser on Windows 10 or 11, macOS, Linux or Ubuntu, and supported Android or iPhone browsers. Device lists, fullscreen and frame counters vary. On phones, choose among the front or rear inputs the browser exposes; system camera permission is separate from site permission. This is a browser test, with no native executable, portable download, Flash plugin, console app or remote-desktop setup. Old Windows XP or Windows 7 browser support is not promised.

Can I test my webcam before a meeting in Zoom, Teams or Google Meet?

This page is useful for checking your local picture, framing and optional microphone input before a meeting. It cannot see the camera or audio settings inside Zoom, Microsoft Teams, Google Meet, Skype, Webex or WhatsApp. After this preview, select the intended inputs and use the meeting app's own preview or test call to check what it receives. Stop this page's streams if the app cannot open the camera. A browser preview is not a network, streaming-platform or call-quality test.

Why could the browser not read my camera?

A read failure can have several causes, including another app using the device, a driver problem or system privacy settings. Close other camera apps, check the input connection and permissions, then retry. If a selected device request cannot be satisfied, choose System default and Auto resolution. These are possible checks, not proof that another application is holding the camera. A browser reporting no available input likewise does not prove no camera is physically connected.

Is my video uploaded, recorded or saved anywhere?

This tool connects local media streams to the preview and optional audio analyser; it has no video recorder, snapshot capture or media upload. Stop, replacement of a stream or leaving the page releases its tracks. Another application may still use the device, so the camera light is not a reliable proof of this page's cleanup. Only mirror and resolution preferences are stored locally after you change them; device identifiers and microphone permission are not saved. Ordinary site requests are separate from camera and microphone media.

Can I record a webcam clip or check an online exam setup here?

There is no webcam video recording, file download or playback test here. A separate Mic Test can record and play back microphone audio. For Duolingo, LockDown Browser, Mettl or another proctored exam, use that provider's official equipment check. This page does not validate exam compatibility, replace proctoring checks or offer exam bypass instructions.

Webcam Test

Test your webcam in the browser and see what your camera sees, and what your browser is actually delivering. Press Start, allow camera access and check the live picture, selected device, decoded resolution and aspect ratio. The frame-rate row separates measurements from browser frame counters and the negotiated rate. Switch between available laptop, USB or virtual cameras, request Auto, 720p or 1080p, flip the mirror and open the preview fullscreen where supported. Add an optional microphone check for a live digital audio meter, or open the combined camera and microphone page. Camera and audio permissions are independent. A refusal, no available camera and a read failure have different next steps; none proves the condition of your hardware. Camera and microphone media remain in this page, with no recording or media upload. Stop releases this page's media tracks.

Browser observations. Access refusal, no available input and a read failure are different results. The messages give possible checks; they do not prove hardware condition or diagnose another app.

What the numbers mean

Resolution buttons request preferred sizes, not guaranteed modes. The page reports the track settings, then the decoded picture dimensions when a frame arrives. FPS uses the presented-frame counter, or a playback-quality frame counter when available. Changes in playback time are never counted as frames. Until a rate is measured, the negotiated value is labelled separately. This browser check cannot prove what Zoom, Teams or another app will receive; test their selected camera and microphone inside that app too.

Accuracy. Shows browser-reported camera settings and decoded picture size. Frame rate is measured from an available frame counter, otherwise labelled as negotiated. Optional audio levels are relative to digital full scale, not room loudness. It cannot know what another app receives. Nothing is recorded or uploaded by this tool. The frames go from the camera to a video element in this page and nowhere else: there is no recorder here and no upload, which is why the tool releases its media tracks when you press Stop or leave. Other applications may still hold the same device.
