Webcam & Microphone Test Online

How This Webcam & Mic Test Works

This free online webcam test uses your browser's built-in WebRTC technology, the same tech that powers video calls on Zoom, Google Meet, Microsoft Teams, and Discord. Click "Start Webcam Test" or "Start Microphone Test," allow access when your browser asks, and the tool shows your live camera feed or audio visualization instantly.

Unlike Zoom's test meeting or Teams' built-in test call, this webcam and mic test works independently of any app. You can check if your camera and microphone are working at the system level before you open your meeting software. If your webcam and mic work here, they'll work everywhere.

This test also doubles as a webcam audio test. You can record video with sound, play it back, and hear exactly how your camera's built-in microphone or your external mic sounds. That makes it useful as a quick sound test before any video call.

Your Privacy Is Protected

This webcam and microphone test runs 100% locally in your browser. No video, audio, or device data is ever uploaded to any server. Your camera feed is rendered using a local video element, and the microphone visualization uses the Web Audio API on your device. Recordings you make are stored temporarily in your browser's memory and deleted the moment you close the tab. You can download them to your computer before leaving.

Webcam Test Features: Preview, Record, and Compare

Live camera preview — see exactly what your webcam captures in real time. The preview shows the same video feed that others see when you join a Zoom call, Google Meet session, or Teams meeting. If your camera is working, you'll see yourself immediately. If nothing appears, scroll down to the troubleshooting section.

Switch between cameras — if you have multiple webcams connected (a built-in laptop camera, an external USB webcam like a Logitech C920 or C922, or a virtual camera from OBS Studio), use the device selector to switch between them. This is useful when your laptop webcam shows a black screen but an external camera works fine.

Webcam mirror and natural view — by default, the preview shows a mirrored image. Toggle to natural view to see yourself exactly as others see you. Most video calling platforms (Zoom, Google Meet, Teams) show you a mirrored view, but transmit the natural view to other participants.

Video filters and adjustments — fine-tune brightness, contrast, saturation, sepia, grayscale, hue rotation, and blur. This helps diagnose camera quality issues: if your webcam image looks too dark, increase brightness; if colors look washed out, boost saturation and contrast.

Record video clips and playback — record yourself directly in the browser and download the clip as a WebM file. Use this webcam recorder to review how you look and sound before a job interview, presentation, or video conference. The recording captures both video and audio from your active camera and microphone.

Microphone Test Features: Visualize, Record, and Play Back

Real-time frequency visualization — see a live audio spectrum of your mic input as you speak, clap, or make sounds. The frequency bars respond instantly. If they don't move, your microphone isn't receiving audio input. This is the fastest way to check if your mic is working before a call. The visualization also helps spot excessive background noise (bars moving when you're silent) or low input volume (bars barely moving when you speak).

Record and play back your voice (mic test playback) — record yourself speaking and listen to the playback to hear exactly how you sound. This catches problems that aren't visible in the visualizer: echo, robotic or distorted voice, background hum from fans or air conditioning, keyboard click noise, or low and muffled audio. If you sound different than expected, try switching microphones or adjusting the audio processing toggles.

Switch between microphones — if you have multiple audio input devices (a built-in laptop mic, a headset microphone, a USB condenser mic like a Blue Yeti or HyperX, AirPods, wireless earbuds, or a Bluetooth headset), use the device selector to switch between them. This helps you compare audio quality across devices and find which mic your system is actually using.

Audio processing controls — toggle noise suppression, echo cancellation, and auto gain control on or off individually. These are the same audio processing features built into your browser that Zoom and Google Meet use. Turn off noise suppression to hear your raw microphone input, or enable echo cancellation to test how it handles speaker feedback.

Download recordings — save your mic test recordings as WebM audio files. Compare microphone quality side by side, send recordings to tech support when troubleshooting audio issues, or keep as a reference before upgrading your mic.

Why Is My Webcam Not Working?

If your camera test shows nothing, a black screen, or an error message, work through these fixes in order. The most common issues are listed first.

1. Camera Permission Is Denied in Your Browser

This is the most common reason a webcam doesn't work on a website. When a page requests camera access, your browser shows a permission popup. If you clicked "Block" or "Deny," the browser remembers that decision and silently blocks all future requests.

How to fix it in each browser:

• Chrome: Click the lock or tune icon in the address bar → "Site settings" → find "Camera" → change to "Allow" → reload the page
• Firefox: Click the lock icon → "Permissions" → click the X next to "Use the Camera" → reload
• Safari: Go to Safari menu → Settings → Websites → Camera → find this website → set to "Allow"
• Edge: Click the lock icon → "Site permissions" → "Camera" → set to "Allow" → reload

If you see NotAllowedError: Permission denied by system, your operating system is blocking camera access. On Windows 11, go to Settings → Privacy & Security → Camera → make sure "Camera access" is toggled on and your browser is in the allowed apps list. On macOS, go to System Settings → Privacy & Security → Camera → check the box next to your browser.

2. Camera Is Being Used by Another Application

Most webcams can only be used by one application at a time. If Zoom, Google Meet, Microsoft Teams, Skype, Discord, OBS Studio, or any other video app is running, it may be holding exclusive access to your camera.

How to fix it:

• Close all other apps that might use your camera, including minimized or background apps
• On Windows: open Task Manager (Ctrl+Shift+Esc) and look for video conferencing apps still running. End their processes
• On Mac: open Activity Monitor and search for "zoom," "teams," "facetime," or "obs." Force quit any you find
• If nothing seems to be using the camera, restart your computer to release any stuck camera locks

3. Webcam Shows a Black Screen

Your camera is detected and there's no error, but the preview is completely black. This is one of the most frustrating webcam issues because everything seems like it should work.

Common causes and fixes:

• Privacy shutter or cover: Many laptops (Lenovo ThinkPad, HP EliteBook, Dell Latitude) have a physical privacy shutter or sliding cover over the webcam. Check for a small slider near the camera lens
• macOS camera process stuck: On Mac, the camera system daemon can hang. Open Terminal and run sudo killall VDCAssistant then sudo killall AppleCameraAssistant. This resets the camera process without a reboot
• Windows camera service stuck: Open Device Manager → Imaging devices → right-click your camera → "Disable device," wait 5 seconds, then "Enable device"
• External webcam: Unplug the USB cable, wait 10 seconds, plug it back into a different USB port (preferably USB 3.0)
• Outdated browser: Update Chrome, Firefox, Safari, or Edge to the latest version. Camera black screen bugs are frequently fixed in browser updates

4. Camera Not Detected (NotFoundError)

The browser can't find any camera device. You'll see NotFoundError: Requested device not found or no camera option in the device selector.

How to fix it:

• USB webcam: Unplug and re-plug the cable. Try a different USB port. Test the camera on another computer to rule out hardware failure
• Built-in laptop webcam: Check Device Manager (Windows) or System Information (Mac) to see if the camera hardware is recognized. If it's missing, the camera may be disabled in BIOS/UEFI
• Windows 11: Go to Settings → Bluetooth & devices → Cameras. If your camera appears with a warning icon, click it and select "Reset." If it doesn't appear, run the built-in troubleshooter: Settings → System → Troubleshoot → Other troubleshooters → Camera

5. Webcam Drivers Are Outdated or Missing (Windows)

After Windows 10 or Windows 11 feature updates, webcam drivers sometimes break or get replaced with incompatible generic versions. This is the most common cause of "camera not working after update."

How to fix it:

• Open Device Manager (right-click Start → Device Manager) → expand "Cameras" or "Imaging devices"
• Right-click your camera → "Update driver" → "Search automatically for drivers"
• If that doesn't help, right-click the camera → "Uninstall device" → check "Delete the driver software" → restart your computer. Windows will reinstall the default driver
• For brand-name webcams (Logitech, Razer, Elgato), download the latest driver from the manufacturer's website

6. Camera Not Working on macOS

macOS handles webcam drivers automatically, but Mac-specific issues do occur:

• After macOS update: Reset the SMC (Intel Macs) or restart in safe mode (Apple Silicon Macs)
• FaceTime HD camera not detected: Run sudo killall VDCAssistant in Terminal. If that fails, reset NVRAM: shut down, then power on while holding Option+Command+P+R for 20 seconds
• Privacy permissions: Go to System Settings → Privacy & Security → Camera → make sure your browser (Chrome, Safari, Firefox, Arc) is listed and checked
• Camera indicator light on but black screen: Another app has the camera. Check Activity Monitor for "avconferenced" or "VDCAssistant" processes

7. Webcam Not Working on Chromebook

Chromebook camera issues are common after Chrome OS updates:

• "Camera unavailable" or black screen in Google Meet: Open Chrome OS Settings → Privacy and Security → Camera → make sure the toggle is enabled. Then try chrome://settings/content/camera and check the correct device is selected
• HP Chromebook privacy switch: Many HP Chromebooks have a physical webcam privacy switch on the left edge. When the switch is off, you'll see a red LED next to the camera. Flip the switch to enable the camera
• Quick fix: Turn the Chromebook completely off (not just closing the lid), wait 30 seconds, and turn it back on

8. Webcam Not Working on iPhone or Android

If the camera test doesn't work on your phone or tablet:

• iPhone / iPad: Use Safari (required on iOS). Go to Settings → Safari → Camera → set to "Allow." If the camera still doesn't work, go to Settings → Privacy & Security → Camera and make sure Safari is enabled
• Android: Use Chrome for the best compatibility. Go to Settings → Apps → Chrome → Permissions → Camera → set to "Allow." If using Samsung Internet, the steps are Settings → Apps → Samsung Internet → Permissions → Camera
• Camera not working on Samsung: On Samsung Galaxy devices, check if another app is using the camera (the green dot indicator in the status bar shows camera activity). Close all apps and try again. If the rear camera works but the front camera doesn't (or vice versa), try switching cameras in the device selector
• Camera not working on iPhone: Make sure you're using Safari, not Chrome or Firefox (they have limited camera access on iOS). If Safari shows a blank screen, restart your iPhone and try again. Check Settings → Privacy & Security → Camera to verify Safari has permission

9. OBS Virtual Camera or Snap Camera Not Showing Up

Virtual cameras from OBS Studio, ManyCam, or mmhmm can sometimes fail to appear:

• OBS Virtual Camera: Make sure OBS is running and Virtual Camera is started. On Windows, try running OBS as Administrator
• Virtual camera not appearing in browser: Some browsers (especially Chrome on macOS) don't list virtual cameras. Try Firefox or Edge instead
• Multiple virtual camera conflicts: Having multiple virtual camera drivers installed can cause conflicts. Disable virtual camera software you're not using

10. Camera Not Working on Lenovo or Dell Laptops

Lenovo and Dell laptops have brand-specific webcam issues:

• Lenovo ThinkPad / IdeaPad: Check for the Lenovo Vantage app. Go to Device → Audio/Video → Camera Privacy Mode and make sure it's OFF. Some ThinkPads have a physical privacy shutter near the camera. Lenovo webcams also frequently break after Windows updates. Use Lenovo Vantage to update drivers
• Dell Latitude / Inspiron / XPS: Check the Dell Peripheral Manager app. Go to Device Manager → Cameras and make sure "Dell Webcam" or "Integrated Webcam" isn't showing a yellow warning. Dell's camera drivers are available from dell.com/support. Enter your service tag for the exact driver for your model

11. Camera Image Is Blurry, Dark, or Laggy

If your camera works but the image quality is poor:

• Dark image: You need more light. Face a window or place a desk lamp behind your monitor. Avoid sitting with a bright window behind you (backlighting)
• Blurry image: Clean your camera lens with a microfiber cloth. For external webcams, check if the lens has a manual focus ring
• Laggy or stuttering video: Close other browser tabs and applications to free up CPU. If using a USB webcam, make sure it's connected to a USB 3.0 port
• Low FPS: Some cheap webcams advertise 30 FPS but only deliver 15 FPS in low light. Improve lighting to get the full frame rate

Why Is My Microphone Not Working?

If the microphone test shows no audio input, no visualization movement, or an error, work through these fixes. The most common causes are listed first.

1. Mic Is Muted by System Settings

This is the most common microphone issue on Google Meet, Zoom, and Teams. Your operating system is blocking microphone access at the system level.

How to fix it:

• Windows 11/10: Go to Settings → Privacy & Security → Microphone → make sure "Microphone access" is toggled on. Scroll down and check "Let apps access your microphone" and "Let desktop apps access your microphone" are both enabled
• macOS: Go to System Settings → Privacy & Security → Microphone → check the box next to your browser
• Chromebook: Go to Settings → Privacy and Security → Microphone → make sure the toggle is enabled

2. Microphone Permission Denied in Browser

If you clicked "Block" or "Deny" when the browser asked for mic access, the browser silently blocks all future microphone requests.

How to fix it:

• Chrome: Click the lock/tune icon in the address bar → "Site settings" → "Microphone" → change to "Allow" → reload
• Firefox: Click the lock icon → "Permissions" → click X next to "Use the Microphone" → reload
• Safari: Safari menu → Settings → Websites → Microphone → set to "Allow" for this site
• Edge: Click the lock icon → "Site permissions" → "Microphone" → "Allow" → reload

3. Wrong Microphone Is Selected

Your computer might have multiple audio input devices (a built-in laptop mic, a headset mic, a USB microphone, and a virtual audio device) and the wrong one may be active.

How to fix it:

• On this page: Use the microphone dropdown in the test tool to switch between devices
• Windows: Right-click the speaker icon → "Sound settings" → under "Input," select your preferred microphone
• Mac: System Settings → Sound → Input → click the microphone you want to use
• In Zoom: Settings → Audio → select the correct mic under "Microphone"
• In Google Meet: Click the three dots → Settings → Audio → choose the correct microphone
• In Teams: Click your profile picture → Settings → Devices → select your microphone
• In Discord: User Settings → Voice & Video → Input Device → select the correct mic

4. Microphone Volume Is Muted or Too Low

Your mic might be working, but the input volume could be at zero.

How to fix it:

• Windows: Right-click the speaker icon → Sound settings → scroll to Input → drag the volume slider up. Click your mic device for advanced options and make sure input volume is at 80-100%
• Mac: System Settings → Sound → Input → drag the "Input volume" slider to the right
• Physical mute buttons: Many headsets (Jabra, Plantronics, HyperX, SteelSeries) and USB microphones (Blue Yeti, Razer Seiren) have a physical mute button with an LED indicator (red = muted)
• Laptop function keys: Some laptops have a mic mute key (usually F4 or a function key with a microphone icon)

5. Microphone Sounds Robotic, Distorted, or Choppy

If people tell you that you sound robotic or your voice cuts in and out during video calls, the problem usually isn't your microphone hardware.

Real causes and fixes:

• High CPU usage: Robotic or choppy audio is almost always caused by your computer being overloaded. Close unnecessary browser tabs and apps. If CPU usage is above 80%, that's likely the cause
• Bad internet connection: On actual video calls (not this test page), robotic voice is often caused by packet loss. Switch from Wi-Fi to Ethernet if possible
• Sample rate mismatch: On Windows, right-click the speaker icon → Sound settings → your microphone → Properties → Advanced → try setting the sample rate to 48000 Hz, 16 bit
• Too much gain: If your mic input volume is at maximum, it can cause distortion. Lower it to around 70-80%

6. Echo and Feedback During Calls

Echo happens when your microphone picks up audio from your speakers and sends it back to the other person.

How to fix it:

• Use headphones: This is the single most effective fix. Headphones prevent your microphone from picking up speaker output
• Lower speaker volume: If you can't use headphones, reduce your speaker volume
• Enable echo cancellation: Toggle the echo cancellation switch in the mic test tool on this page. In Zoom, go to Settings → Audio → check "Suppress background noise"
• Multiple devices in one room: If two or more people join the same call from devices in the same room, mute all devices except one, or have everyone use headphones

7. AirPods and Bluetooth Earbuds Microphone Issues

AirPods, AirPods Pro, Galaxy Buds, and other Bluetooth earbuds are the most common source of mic problems on video calls.

Known issues and fixes:

• Wrong Bluetooth profile: Bluetooth uses two profiles: A2DP (stereo audio, no mic) and HFP/HSP (call quality, with mic). When your mic activates, audio quality drops because Bluetooth switches to HFP. This is a Bluetooth limitation, not a bug
• AirPods mic not working on Zoom/Meet: On Mac, go to System Settings → Sound → Input → select "AirPods." In Zoom, go to Settings → Audio → select AirPods under "Microphone." AirPods sometimes default to the laptop mic
• AirPods only one side working: Put both AirPods in the charging case, wait 15 seconds, take them out, and reconnect
• Low mic quality on Bluetooth: If call audio quality is unacceptable, switch to a wired headset or USB microphone. Bluetooth mic quality is inherently limited

8. USB Microphone Not Detected

USB microphones like the Blue Yeti, Audio-Technica AT2020USB, Rode NT-USB, Elgato Wave, and HyperX QuadCast sometimes aren't recognized.

How to fix it:

• Unplug the USB cable, wait 10 seconds, plug it into a different USB port. Prefer USB 3.0 ports and avoid USB hubs
• Windows: Open Device Manager → "Audio inputs and outputs" → check if your mic appears. If it shows a yellow warning, right-click → "Uninstall device" → unplug → plug back in
• Mac: Open System Settings → Sound → Input. If the USB mic doesn't appear, reset Core Audio: open Terminal and run sudo killall coreaudiod
• Check the mic's controls: Some USB mics have a gain knob, mute button, or headphone/mic toggle. Make sure the mic isn't muted and gain is turned up

9. Microphone Not Working on iPhone or Android

If the mic test doesn't pick up audio on your phone:

• iPhone: Use Safari (required on iOS). Go to Settings → Safari → Microphone → set to "Allow." If the mic still doesn't work, check Settings → Privacy & Security → Microphone. Try restarting your iPhone
• Android: Use Chrome. Go to Settings → Apps → Chrome → Permissions → Microphone → set to "Allow"
• Samsung phones: Samsung has additional audio settings. Go to Settings → Sounds and vibration → Sound quality and effects → make sure nothing is interfering. Also check Settings → Apps → your browser → Permissions → Microphone
• Microphone blocked by phone case: Some phone cases partially cover the microphone hole. Remove the case and test again

10. Microphone Works in One App but Not Another

Your mic works in this test or in one app, but not in Zoom, Teams, Discord, or Google Meet specifically.

How to fix it:

• Check in-app settings: Each app has its own microphone selector that can override the system default
• Exclusive access: Some apps (especially on Windows) take exclusive control of the mic. Close the app holding the mic, then try again
• macOS permissions: Each app needs individual mic permission. Go to System Settings → Privacy & Security → Microphone and check the non-working app
• Discord-specific: In Discord, go to User Settings → Voice & Video → make sure the correct Input Device is selected. Try toggling "Automatically determine input sensitivity" off and adjusting the slider manually
• Browser extensions: Privacy-focused extensions (uBlock Origin, Privacy Badger, NoScript) can block getUserMedia requests. Try an incognito window with extensions disabled

11. Background Noise and Poor Audio Quality

Your microphone works, but people complain about keyboard clicks, fan noise, or general hum.

How to fix it:

• Enable noise suppression: Toggle noise suppression on in the test tool above. In Zoom, set "Suppress background noise" to "High"
• Microphone position: Keep your mic 6-12 inches from your mouth. Too far picks up room noise; too close causes plosives (popping on P and B)
• Use a directional microphone: Cardioid microphones (most headset mics and USB condenser mics) pick up sound mainly from the front. Omnidirectional mics (most laptop built-in mics) pick up everything
• Software noise cancellation: Apps like Krisp, NVIDIA Broadcast, or the built-in noise cancellation in Zoom and Google Meet can reduce background noise in real time

Test Your Camera & Mic Before a Meeting

Different video conferencing platforms have their own camera and mic tests. But those built-in tests only check if the device works within that specific app. If you want to verify that your camera and mic work at the system level before you open the app, use the webcam and microphone test at the top of this page first.

Test Camera Before a Zoom Meeting

Zoom has a dedicated test meeting at zoom.us/test. You can also test without joining a meeting: open the Zoom desktop app, click your profile picture → Settings → Video to preview your camera, and Settings → Audio to test your speaker and microphone. If your camera doesn't work in Zoom but works in our test above, check Zoom's in-app camera selector.

Test Camera Before a Google Meet Call

Google Meet doesn't have a standalone test tool, but you can preview your camera and mic before joining any meeting: click the meeting link, and on the preview screen you'll see your video feed and can select your camera and microphone. If you see a camera icon with a red slash, Meet doesn't have permission. Click the camera icon in your browser's address bar and allow access.

Test Camera Before a Microsoft Teams Meeting

In Microsoft Teams, click your profile picture → Settings → Devices. You'll see a camera preview and can select your audio and video devices. Teams also shows a preview screen before you join any meeting. If Teams says "No camera found," make sure your browser or the Teams desktop app has camera permission in your OS settings.

Test Camera Before a Discord Call

In Discord, go to User Settings (gear icon) → Voice & Video. You'll see your input and output device selectors, a mic test button, and a camera preview. If your webcam doesn't appear in Discord, make sure Discord has camera permission in your OS settings and that no other app is using the camera.

Test Camera Before a WebEx Meeting

In Cisco WebEx, go to Settings → Audio & Video before joining a meeting. You can test your speaker, microphone, and camera. WebEx also shows a pre-join preview where you can verify your video feed.

Test Camera Before a Flat.social Session

On Flat.social, you'll see a device selection screen before entering any room. Select your preferred camera and microphone, check the preview, and join when ready. If your devices don't appear, use the troubleshooting steps on this page to fix the issue first.
