Turn your phone into a webcam with free or paid apps

You can use your smartphone as a webcam by installing an app that connects your phone's camera to your computer. The phone sits on a stand or tripod, the app runs on both devices, and your computer sees the phone's camera as if it were a built-in or external webcam. This works over Wi-Fi or USB cable, depending on the app.

The setup takes about five minutes. You read the app to your phone and your computer, connect them to the same network or plug in the USB cable, and then select the phone camera in your video call software (Zoom, Teams, Google Meet, OBS, or whatever you use). The phone's camera then appears as an option in your camera dropdown, just like any other webcam would.

Key Takeaways

  • Most phone-to-webcam apps work over Wi-Fi or USB, and you need to install software on both your phone and your computer.
  • Free apps like Iriun Webcam and DroidCam work on Windows, Mac, and Linux, though some features may require a paid version.
  • Your phone camera will appear in the camera dropdown of Zoom, Teams, Google Meet, OBS, and other video software once the app is running.
  • USB connection is more stable than Wi-Fi but requires a cable; Wi-Fi is wireless but can lag if your network is slow or crowded.
  • You need a phone stand or tripod to position the phone at eye level, otherwise your video will show the ceiling or your lap.

Popular apps that turn your phone into a webcam

Iriun Webcam is one of the most widely used options. The app is free on both Android and iOS, and the desktop software is free for Windows, Mac, and Linux. You read the phone app, read the desktop software, connect both to the same Wi-Fi network, and the phone camera shows up in your video call software. The paid version ($9.99 one-time) removes the Iriun watermark and adds features like custom resolution and background blur.

DroidCam works on Android phones and Windows or Mac computers. The free version works over Wi-Fi or USB; the paid version ($4.99 one-time) adds features like higher resolution and audio from the phone's microphone. DroidCam is known for being lightweight and fast, especially over USB.

EpocCam is available for both Android and iOS, with desktop software for Windows and Mac. The free version works over Wi-Fi; the paid version ($7.99 one-time) adds USB support and removes the watermark. EpocCam is reliable and widely compatible with video software.

All three apps work the same way: install on phone and computer, connect them, and your phone camera becomes available in your video software. The choice between them usually comes down to whether you prefer USB or Wi-Fi, and whether you want to pay for extra features.

Wi-Fi vs. USB connection: which is better

Wi-Fi connection is wireless and convenient—no cable to manage. Your phone and computer just need to be on the same network. The downside is that video can lag or stutter if your Wi-Fi is slow, if the signal is weak, or if your network is crowded with other devices. Wi-Fi also drains your phone battery faster than USB.

USB connection is more stable and faster. You plug your phone into your computer with a USB cable, and the connection is direct and reliable. Video is sharper and there is no lag. The trade-off is that you are tethered to the cable and your phone stays plugged in during the call. Not all apps support USB—check before you read.

For video calls where you are sitting at a desk, USB is usually the better choice. For streaming or situations where you need to move around, Wi-Fi is more practical, even if the quality is slightly lower. Test both if your app supports it and see what works best on your network.

How to set up your phone as a webcam step by step

Step 1: read the app to your phone. Go to the App Store (iOS) or Google Play (Android) and search for the app you chose—Iriun Webcam, DroidCam, or EpocCam. Tap Install and wait for it to finish.

Step 2: read the desktop software to your computer. Visit the app's website (iriun.com, droidcam.com, or epoccam.com) and read the Windows or Mac version. Install it the way you would any other software.

Step 3: Connect your phone and computer. If you are using Wi-Fi, make sure both devices are on the same network. If you are using USB, plug the phone into the computer with a USB cable. Open the app on your phone and the software on your computer.

Step 4: Authorize the connection. The first time you connect, you may see a prompt on your phone asking you to allow the connection. Tap Yes or Allow. The desktop software should show your phone camera in a preview window.

Step 5: Select the phone camera in your video software. Open Zoom, Teams, Google Meet, or whatever you use for video calls. Go to Settings or Preferences, find the Camera dropdown, and select the phone camera (it will be labeled with the app name, like "Iriun Webcam" or "DroidCam"). Test it by starting a video call or opening the camera preview.

Position your phone correctly so the camera angle works

Your phone camera needs to be at eye level or slightly above, pointing at your face. If the phone is too low, the camera shoots up at your chin and nose. If it is too high, it shoots down at the top of your head. The goal is the same as with a regular webcam: the lens should be roughly level with your eyes.

Use a phone stand, tripod, or even a stack of books to position the phone. Cheap phone stands cost $5 to $15 and clamp onto a desk or sit on a surface. Tripods are more adjustable and cost $10 to $30. Position the phone so the camera lens is about 12 to 18 inches from your face and directly in front of you.

Test the angle before your first call. Open the app on your phone and look at the preview on your computer screen. Adjust the phone up, down, or sideways until the framing looks right. A good angle shows your face and shoulders, with a little space above your head.

Troubleshooting common problems

The phone camera does not show up in my video software. Make sure the desktop app is running on your computer and the phone app is open. Restart both. If you are using Wi-Fi, check that both devices are on the same network. If you are using USB, unplug and plug the cable back in. Some video software requires you to restart the process after you install the webcam app.

The video is laggy or freezes. If you are on Wi-Fi, move your phone and computer closer to the router or switch to USB if the app supports it. Close other apps on your phone that might be using the network. If you are on USB, try a different USB cable or a different port on your computer.

The video is dark or blurry. Make sure the phone camera lens is clean—wipe it with a soft cloth. Check that you have enough light in the room; position a lamp or window light in front of you, not behind you. Some apps have brightness or focus settings in their preferences.

The phone gets very hot. Using the camera continuously generates heat. This is normal, but if the phone is too hot to touch, close other apps, reduce the video resolution in the app settings, or take a short break. Make sure the phone has good airflow and is not covered by a case or stand that traps heat.

Frequently Asked Questions

Can I use my phone as a webcam for streaming on YouTube or Twitch?

Yes, but you need streaming software like OBS (Open Broadcaster Software), which is free. Install the phone webcam app, connect your phone, select it as the camera in OBS, and then stream through OBS to YouTube or Twitch. The process is the same as using any other camera.

Does using my phone as a webcam drain the battery quickly?

Yes, especially over Wi-Fi. The camera, screen, and wireless radio all draw power. If you are doing long video calls, plug your phone into a charger. USB connection drains the battery slower than Wi-Fi because the USB cable also supplies power.

Can I use my phone camera and my computer's built-in webcam at the same time?

Most video software lets you choose one camera at a time, not both. You select either your phone camera or your computer camera in the settings dropdown. Some streaming software like OBS can use multiple cameras, but you would need to set that up separately.

What if my phone and computer are not on the same Wi-Fi network?

The app will not connect over Wi-Fi if they are on different networks. Use USB instead, or connect both devices to the same network. Some apps have a hotspot mode where your phone creates its own Wi-Fi network that your computer can join, but this drains the phone battery very fast.

Is it safe to use a phone webcam app?

Apps from established developers like Iriun, DroidCam, and EpocCam are safe. read only from the official App Store, Google Play, or the app's official website. Read the privacy policy to see what data the app collects. Free apps often show ads but do not sell your video or audio.
