Webcam Test: Check Your Camera Online

What this webcam test checks

Beyond confirming your camera is detected and showing a picture, this tool reports the technical details your browser can see about it, resolution, frame rate, aspect ratio, and more, and lets you record a short test clip rather than just glancing at a live feed. Most webcams built into laptops and monitors also have a microphone built in right next to the lens, so if you're checking your camera before a call, it's worth testing that mic too rather than assuming it's fine just because the picture looks good.

How to use the webcam test

• Click to start the test and allow camera access when your browser asks.
• Check the live preview to confirm you can see yourself or whatever the camera is pointed at.
• Review the technical details panel for a closer look at resolution, frame rate, and other properties.
• Optionally record a short clip to catch anything a quick glance might miss.

Testing on a Chromebook

This works fine on Chromebook, but ChromeOS handles camera permissions a bit differently from Windows or Mac. Instead of a separate system privacy panel, ChromeOS manages camera access per site through the small padlock or settings icon in the browser's address bar, alongside a quick toggle in the system tray for enabling or disabling the camera hardware entirely. If access seems blocked, check both of these rather than looking for a Windows-style privacy settings menu that ChromeOS doesn't have.

Testing on mobile

On a phone or tablet, tap to start the test the same way, and allow camera access when prompted. Most phones will let you switch between front and rear cameras during the test, useful if you want to check both.

What your results mean

Understanding the technical details

Worth being upfront about where these numbers come from: they reflect what your browser itself can measure and process, which can differ slightly from a manufacturer's official spec sheet or a dedicated capture utility's reading. Treat them as a solid, practical read on your camera's real-world performance rather than a certified lab benchmark.

Why you look mirrored in the preview

If text on your shirt or a sign behind you looks backwards during the test, that's completely normal and not a bug. Most camera previews, this one included, show you mirrored, the same way a bathroom mirror or a selfie camera does, since that's generally more intuitive to look at while positioning yourself. The video that actually gets sent out on a real call is typically un-mirrored, meaning other people see you the correct way around, even though your own preview looked flipped. Don't worry if something looks reversed here, it won't look that way to anyone else.

Why low light makes your image grainy

When there isn't much light for your camera's sensor to work with, it compensates by amplifying the signal it does receive, essentially boosting a weak input to produce a usable image. That amplification is what creates the speckled, grainy look you'll notice in dim rooms. It's not a flaw in your specific webcam, it's how small camera sensors generally behave under low light. Adding more light in front of you, rather than behind you, is the most direct fix, since it gives the sensor more real signal to work with instead of relying on amplification.

Recording a test clip vs a live preview

A quick glance at the live preview is enough to confirm your camera basically works, but recording a short clip and playing it back can catch things a live look often misses. Autofocus hunting, where the camera visibly refocuses back and forth, is much easier to notice on playback than in the moment. The same goes for compression artifacts introduced by whatever software ends up recording you, or audio sync drifting slightly out of alignment with video. If you're preparing for something important, a job interview, a client call, a recorded presentation, it's worth taking the extra few seconds to record and review a test clip rather than trusting the live preview alone.

Troubleshooting common issues

Camera isn't detected at all, or doesn't appear in any device list:

• Check that an external webcam is securely plugged in, and try a different USB port.
• Update your webcam's driver, or your operating system's built-in camera driver if it's a laptop's built-in camera.
• Confirm the camera isn't disabled at the hardware level, some laptops have a physical shutter or a keyboard shortcut that disables the camera.

Camera is detected but shows black, frozen, or a single solid color:

• Close other applications that might be using the camera. Many apps hold exclusive access while running, which blocks everything else, including this test, from getting a picture.
• Check for a physical lens cover or sliding shutter that might be closed.
• Refresh the page and try granting camera permission again.

You allowed camera access but it's still not working: There are generally two separate layers of permission that both need to be granted, your browser's own site-level permission, and your operating system's overall camera privacy setting. Granting one without the other is a common reason access still seems blocked. Check both your browser's site settings and your system's privacy or camera settings.

Most webcams come with a built in microphone, so it's a good idea to test your microphone, too and make sure both your camera and audio are working as expected. You can also check your display to better evaluate your webcam's image quality.
