Webcam Not Working? 11 Fixes That Actually Solve It
Black screen, "camera in use", or no camera found? Work through these fixes for Windows, macOS, Chrome, Edge, Firefox and Safari, from the most common cause to the rarest.
Online Camera Team5 min read
When a webcam stops working, the cause is rarely the camera itself. In our experience it’s almost always one of a handful of boring things: a permission switched off, another app holding on to the camera, or a physical shutter you forgot existed. The trick is checking them in the right order so you’re not reinstalling drivers when the real fix was sliding a little plastic cover.
Here are the fixes, roughly from most to least likely.
First, read the error
If you’re using a browser-based camera, the error message actually tells you a lot. Browsers report camera failures with a few standard names, and good tools translate them for you:
- Permission denied / NotAllowedError: the browser or the operating system has blocked access. Go to fixes 2 and 3.
- Camera in use / NotReadableError: something else has the camera open, or the driver has crashed. See fix 4.
- No camera found / NotFoundError: the system can’t see any camera at all. Jump to fixes 5–8.
- Overconstrained: the requested resolution or frame rate isn’t supported. Pick a lower resolution.
Our online camera and webcam test both show these in plain language with steps to fix them, which saves some guesswork.
1. Check the physical stuff
It feels silly, but start here. Many laptops now have a sliding privacy shutter over the lens. Some have a dedicated keyboard key (often one of the F-keys with a little camera icon, sometimes combined with Fn) that cuts power to the camera entirely. On a few models the shutter is a tiny switch on the side of the chassis.
If you’re using a USB webcam, unplug it, wait five seconds, and plug it into a different port, ideally one directly on the computer rather than a hub or dock. Unpowered hubs are a classic source of cameras that connect, then vanish.
2. Allow the camera in your browser
Each browser remembers camera permissions per site. If you clicked “Block” once, even by accident, it will keep blocking quietly.
- Chrome and Edge: click the icon to the left of the address bar, find Camera, and set it to Allow. Reload the page.
- Firefox: click the camera or permissions icon in the address bar and clear the blocked permission, then reload.
- Safari: open Safari’s Settings, go to Websites, then Camera, and set the site to Allow.
Also make sure the page is on HTTPS. Browsers won’t offer camera access to insecure pages at all.
3. Allow the camera in your operating system
This one catches a lot of people, because the browser can be set to Allow while the operating system is still saying no.
Windows 11: open Settings, then Privacy & security, then Camera. Make sure Camera access is on, Let apps access your camera is on, and scroll down to make sure Let desktop apps access your camera is on too. Chrome, Firefox and most video apps count as desktop apps.
Windows 10: it’s the same idea under Settings, then Privacy, then Camera.
macOS: open System Settings, then Privacy & Security, then Camera, and switch on the browser or app you’re using. macOS often wants you to quit and reopen the app after changing this, so do that before assuming it didn’t work.
4. Close whatever else is using the camera
On many systems, especially Windows, a camera can only be used by one app at a time. If Zoom, Teams, Skype, Discord, OBS, or a webcam utility from your laptop maker is running in the background, it may be holding the camera hostage. Quitting the visible window isn’t always enough, as some of these apps live in the system tray. Right-click their tray icons and quit properly.
Don’t forget other browser tabs. A Google Meet tab you left open from this morning can block a new camera page.
5. Restart the browser, then the computer
Yes, really. Camera drivers occasionally get stuck in a bad state, especially after the computer wakes from sleep. Fully quit the browser (not just the window) and reopen it. If that doesn’t help, restart. It fixes a surprising number of “camera in use” errors where nothing is visibly using the camera.
6. Check Device Manager on Windows
Right-click the Start button and open Device Manager. Look under Cameras or Imaging devices.
- If the camera has a down-arrow icon, it’s disabled. Right-click it and choose Enable device.
- If it has a yellow warning triangle, right-click and choose Update driver. If the problem started after an update, try Properties, then Driver, then Roll Back Driver.
- If it’s not listed at all, choose Action, then Scan for hardware changes.
7. Look at your antivirus or security software
Several security suites include “webcam protection” that blocks camera access for apps they don’t recognise. If you have one installed, open it and look for a webcam or privacy section. You may need to add your browser to an allow list.
8. Check work or school restrictions
Managed laptops sometimes have the camera disabled by policy, or restricted to specific apps. If the camera works in Teams but nowhere else, this may be why. Your IT team is the only real fix here.
9. Try a different browser
If the camera works in Edge but not Chrome, you’ve learned something useful: the hardware is fine, and the problem lives in one browser’s settings or extensions. Try disabling extensions, especially privacy blockers, or test in a private window, which usually runs without them.
10. Lower the resolution
Some older or budget webcams misreport what they support. If you’ve chosen 1080p or 4K and get an error or a black frame, drop to 720p or “Auto”. Our resolution test will show you which modes your camera genuinely handles.
11. Test the camera somewhere else
If nothing above works, try the camera in a built-in app: the Camera app on Windows, Photo Booth on a Mac, or the Camera app on a Chromebook. If it fails there as well, after a restart, with permissions on and nothing else running, you’re likely looking at a hardware fault or a driver your manufacturer needs to fix. For a USB webcam, try it on a different computer to settle it for sure.
When the camera works but looks terrible
Sometimes the camera “works” but the picture is dark, grainy, or choppy. That’s usually lighting, not a fault. A dim room drops your frame rate and adds noise. Before buying anything new, read our guides on webcam frame rate and looking better on camera. A lamp pointed at your face fixes more webcam problems than any driver update.
Quick checklist
If you’re in a hurry, run through this list: shutter open, camera key on, browser permission set to Allow, OS permission on, other video apps fully quit, browser restarted. That covers the vast majority of cases. Then open the webcam test to confirm everything is back to normal.
