Looking for a screen test or display test instead - for stuck or dead pixels, color uniformity, or backlight bleed on a monitor or laptop screen? Use our LCD & display test (full-screen color cycle). This page checks your webcam (front/back camera and resolution) in the browser; it does not test the screen or the microphone (use our microphone test for that).
Also called a webcam test, front-camera test, or device camera test - the same in-browser preview covers all three names and works on laptops, desktops, tablets, and phones.
Free Online Camera Test - Instantly Check Your Webcam and Mobile Camera Quality
Need to quickly verify your camera's quality for a video call or recording? Use our free online camera test tool to assess your camera's video performance instantly-no downloads needed. This secure, browser-based tool works across all devices, including laptops, desktops, tablets, and mobile phones, making it perfect for on-the-go camera testing.
How a browser-based camera test actually works
When you open this page, your browser calls the getUserMedia API to ask the operating system for a live video stream from the connected camera. Once the OS grants access and you confirm the browser prompt, the raw frames flow straight into a <video> element on the page. Nothing is recorded or uploaded - what you see on screen is what the browser receives in real time, which is the same feed Zoom, Google Meet, and Microsoft Teams consume during a call. If the preview looks correct here, it will look correct in those apps too.
Troubleshooting a "no signal" result
The majority of camera-test failures trace back to one of five causes. Work through them in order.
- Browser permission. Click the camera icon in the address bar and re-grant access for
freetoolonline.com. On Chrome, Site settings → Camera must be set to Allow; a blocked permission produces an instant black frame. - Secure origin (HTTPS). Modern browsers expose
getUserMediaonly overhttps://. Loading the page over plain HTTP silently returns no stream. - OS-level privacy. macOS: System Settings → Privacy & Security → Camera and enable your browser. Windows: Settings → Privacy & security → Camera. Linux: confirm the user has access to
/dev/video0. - Device in use elsewhere. Zoom, Teams, OBS, and the native Camera app on Windows often hold an exclusive lock on the webcam. Quit other apps and reload.
- Mobile sensor quirks. iOS Safari requires a user gesture (a tap) before the first sensor read, and blocks motion sensors when the page is inside a cross-origin iframe. Android Chrome occasionally hides additional rear lenses from the browser.
Desktop vs mobile test differences
| Capability | Desktop browser | Mobile browser |
|---|---|---|
| Live preview | Yes | Yes |
| Resolution readout | Accurate, reflects the first matched MediaTrackConstraint | Accurate, but limited to the OS-reported mode |
| Switch front / rear camera | N/A | Yes, via the camera-select control |
| Frame-rate read | Yes | Varies by browser |
| Permission prompts | Once per site per OS user | Once per tab unless saved |
Privacy
The camera feed stays on your device. Frames are rendered to a local <video> element, never encoded for upload, and the stream ends the moment you close the tab. No frames are cached and nothing is written to disk.

Test camera, camera check, camera test online - the same in-browser tool
Whether you searched for test camera, camera check, camera test online, online camera test, or simply camera test, this page is the same tool: it asks the browser for live access to your webcam (or front / rear phone camera) via the browser's getUserMedia API, renders the feed locally in a <video> element, and ends the stream the moment you close the tab. There is no upload step on the client-side preview path - the frames stay on your device, and the resolution and frame-rate the browser reports are the same numbers Zoom or Google Meet will see during a call.
If you arrived from a search like online webcam test or test my camera, the steps above (Start Camera, allow permissions, confirm preview) cover the full check; the language differs but the diagnostic is the same.
Also checking your input hardware before a call? Pair this with the microphone test to verify audio levels, and run a keyboard test if any key has felt unresponsive - the three tests cover the full video-call input surface in under a minute.

Frequently Asked Questions
Can I test my camera on a smartphone or tablet?
Yes, this tool is compatible with mobile devices. You can switch between front and rear cameras on your device to assess quality for both.
How do I know if my camera is working properly?
After allowing camera access, you should see a live video feed. Clear video feed means the camera is functional. If there's an issue, try troubleshooting below.
What should I do if my camera isn't working?
If you encounter issues, follow these steps:
- Verify that your browser has camera access permissions.
- Close other applications that may be using the camera.
- If using an external webcam, try reconnecting it.
- Ensure camera drivers are updated.
- Restart your device if issues persist.
Is my camera data safe while using this tool?
Yes, absolutely. This tool operates locally in your browser, and no video data is stored or shared externally.
Why should I test my camera before a video call?
Testing your camera ahead of time ensures you avoid technical issues, allowing you to maintain professional video quality for calls or live streaming.
The tool shows "no camera detected" - what is the most common cause?
The browser permission is the usual culprit. Chrome, Edge, and Firefox require HTTPS and an explicit Allow click; if you clicked Block earlier, the prompt will not reappear. Click the camera icon in the URL bar (or Site settings → Camera), set to Allow, and reload the page. On macOS Sonoma and later, also check System Settings → Privacy & Security → Camera and confirm your browser has OS-level access.
Can I test my phone's front camera with this tool?
Yes. The tool requests the default camera, which on most phones is the front-facing one. If it opens the rear camera instead, use the "Switch camera" control in the tool UI, or reload the page after granting permission - the camera-selection prompt usually appears on the second attempt. iOS Safari and Chrome both support this flow; Android browsers behave the same way.
