Click "Start test" and allow camera access to begin.
Here's how to test your webcam online in under a minute — no software, no account.
Click "Start test."
Your browser will ask for camera permission — click "Allow." If you don't see a prompt, check the address bar for a blocked-permission icon.
Check the live preview.
You should see yourself, or whatever the camera is pointed at, within a second or two. That alone confirms the camera and browser are connected properly.
Switch cameras if you have more than one.
The device list appears once permission is granted. Pick a different camera from the dropdown to test it without reloading the page.
Take a test photo.
Click "Take photo" to capture a still frame. It's a quick way to check focus, lighting, and image quality beyond just the live preview.
Review the camera info panel.
Check the resolution and frame rate your camera is actually delivering — useful to know before a video call or stream.
Who tests a webcam, and why
Remote workers run this before an important call or interview, especially on a new laptop or after a Windows or macOS update that has a habit of quietly resetting camera permissions. Streamers and content creators check their setup before going live, since a frozen or disconnected camera is the kind of mistake you only want to make once in front of an audience. Anyone who's just bought a new webcam runs it out of the box to confirm it actually works and to see what resolution it really delivers before the return window closes. Parents and students test a laptop's camera before online classes for the same reason — better to catch a problem with ten minutes to spare than at the start of a lesson. And when a camera "stops working" out of nowhere, this is usually the fastest way to tell whether it's the hardware, the app, or a permission setting that's actually at fault. Since a video call depends on both ends of the AV chain, most people testing a camera before a call also run our Mic Test to confirm their microphone is picking up sound just as reliably.
How this webcam test actually works
Clicking "Start" triggers your browser's getUserMedia API, which asks permission and then hands back a live video stream that's drawn directly onto this page — the same underlying mechanism every video-calling app uses. Nothing about that stream is recorded, saved, or sent anywhere unless you explicitly take a snapshot; close the tab and the feed simply stops existing. There's no server on the other end receiving your camera feed at any point, which is worth knowing given how often "webcam test" searches are one step away from a genuinely sketchy site.
Troubleshooting, matched to what you're actually seeing
No camera detected at all
Check the permission prompt didn't get dismissed or blocked.
Look for a blocked-camera icon in your browser's address bar — clicking it usually lets you flip the permission back to Allow without reloading from scratch.
Confirm no other app is holding the camera.
Most operating systems only let one application access a camera at a time. Fully close Zoom, Teams, or any other video app — minimizing isn't always enough.
Check the system-level camera privacy toggle.
This is separate from the browser's own permission and catches a lot of people who've already checked the browser setting twice.
The preview is black but the camera light is on
This specific combination — active light, no image — almost always points to a driver or app-level conflict rather than a broken sensor. Try a full restart before anything else; camera drivers on Windows in particular are known for getting stuck in a bad state that only a reboot clears. If a restart doesn't help and you're on a dedicated webcam rather than a laptop's built-in camera, Logitech's own support site is worth checking for the most common external webcam brand.
The image is frozen, laggy, or very low resolution
A frozen frame usually means the stream itself dropped while the last frame stayed on screen — refreshing the page reconnects it. Consistently low resolution or a laggy feed is more often a USB bandwidth issue than a setting: try a different USB port, ideally not through a hub shared with other high-bandwidth devices.
Camera privacy settings, by operating system
Windows 10 & 11
Open Settings → Privacy & Security → Camera. Confirm the global "Camera access" toggle is on, then scroll down and check your specific browser is also enabled in the app list underneath — both switches need to be on independently.
macOS
Open System Settings → Privacy & Security → Camera. Your browser should appear in this list with a toggle; if it's missing entirely, trigger the permission prompt again from this page and click Allow when macOS asks.
ChromeOS, Android & iOS
On ChromeOS, camera permission is managed per-site under the browser's own site settings rather than a separate system panel. On Android, check Settings → Apps → [your browser] → Permissions → Camera; on iOS, check Settings → [your browser] → Camera.
Webcam problems at a glance
Match what you're seeing to what's probably actually going on.
Symptom
Likely cause
Quick fix
No preview shows up at all
Permission's blocked, or the wrong camera's picked
Check the site's camera permission first, then check the device dropdown
Browser never even asks for permission
You already said no once, and it remembered
Reset the site's permission from the address bar and reload
"Camera already in use" error
Something else has it open — Zoom, Teams, Discord
Close whatever else might be using it and try again
Picture's really dark
Not enough light, or the camera's doing its best in low light
Add some light facing you, and cut down on backlight behind you
Video's choppy or laggy
Frame rate's low or unstable, usually a bandwidth or CPU thing
Close other heavy tabs and apps, then check the frame rate reading above
Image looks blurry
Focus needs adjusting, or the lens is just dirty
Give the lens a gentle wipe and look for a manual focus ring
Works in the browser, not in some other app
That app's own camera permission is off, separate from your browser's
Dig into that specific app's settings and check its camera device
Understanding your camera's specs
The camera info panel above shows a few numbers that are worth understanding, since they explain a lot about why one webcam looks noticeably better than another.
Resolution is the number of pixels your camera captures, written as width × height — 1280×720 (often called 720p) or 1920×1080 (1080p) are common examples. More pixels generally means a sharper, more detailed image, though lens quality and lighting matter just as much in practice.
Frame rate, measured in frames per second (FPS), is how many images your camera captures every second. 24–30 FPS looks smooth for normal video calls; anything noticeably lower tends to look choppy, especially when you move.
Aspect ratio is the shape of the image — 16:9 is the modern widescreen standard most webcams use, while some older or specialty cameras use 4:3, a slightly more square shape.
Megapixels is simply the resolution expressed as a total pixel count — a 1920×1080 image works out to roughly 2.1 megapixels. It's a useful shorthand, but not the full picture of image quality on its own.

Testing a laptop webcam vs. an external webcam
This webcam tester works the same way for either one, but what you do with the result differs a bit.
A laptop's built-in camera is fixed in place and usually fine to just confirm working or not — if the image looks dim or soft, that's often just the hardware's limits rather than something to fix. A USB webcam has more to check: position and angle, focus (some have a manual ring), and whether it's mounted somewhere that catches good light. It's worth taking a test photo with each to compare image quality side by side, not just confirming the preview appears.
If you're deciding whether a new USB webcam is actually worth using over your laptop's built-in one, compare the resolution and frame rate readings from this test for both, and look at a captured photo from each in similar lighting — the numbers alone don't always tell the full story.
Frequently asked questions
The camera light is on, but I just see a black screen — what's going on?
That combo almost always means a driver or app conflict, not a dead sensor. A full restart fixes it more often than fiddling with any setting — especially on Windows.
Does this site record or save my video anywhere?
No. The feed gets drawn straight onto this page using your browser's own camera API — nothing gets recorded, saved, or sent anywhere unless you tap "Take photo" yourself.
How do I know if my webcam is actually working?
Hit "Start test" above and let the browser grab camera permission. If the camera's actually working, you'll see yourself — or whatever it's pointed at — pop up within a second or two.
Why won't my browser pick up my webcam at all?
Nine times out of ten it's a permissions thing, not a dead camera. Check your browser's site settings and make sure camera access is switched on for this page, and that nothing else has it locked up in the background.
Is my video being sent somewhere while I'm testing this?
No. Everything runs locally in your browser. If you take a photo, it's generated right there on your device and never leaves unless you choose to download it yourself.
Can I test an external USB webcam here too?
Yep. Doesn't matter if it's a built-in laptop cam, a USB webcam, or your phone running as a webcam — as long as your OS sees it, it'll show up in the list once you approve the permission.
What does frame rate (FPS) actually mean, and why should I care?
It's how many images your camera grabs every second. Higher and steadier usually means smoother video calls; low or jumpy frame rate is what makes video look choppy or laggy.
Why does my webcam show me backwards, like a mirror?
It's flipped on purpose so it feels like looking in a mirror while you're positioning yourself — that's how most video call apps show you your own feed too. Whoever's on the other end sees you the right way round.
My camera works on Zoom but not here (or the other way round) — why?
Each app handles camera permissions on its own, so it's pretty common for one to work and another not to. Check that specific app's own camera settings — there's a good chance it's pointed at the wrong device.
Will this work on my phone?
Should work fine as long as you're on a reasonably current mobile browser and tap allow when it asks for camera access. Works with both the front and back camera.
Why does the video look dark or grainy?
Low light is almost always the culprit — webcams need a lot more light than your eyes do to look clean. Also worth checking the resolution reading above actually matches what your camera's capable of.
