How to Use the Virtual Ring Light
Configure your light
Choose a preset or adjust brightness and color temperature manually. Daylight (5000-6500K) looks neutral on camera. Warm (2700-3500K) can feel softer for selfies.
Position your screen
Place your screen directly in front of you at eye level, as close as possible to your webcam. The closer the screen, the stronger the front illumination.
Go fullscreen, start your call
Press F or tap Fullscreen for maximum coverage. Open your video call or camera app on another screen or device. The ring light runs independently as your light source.
Privacy
No camera required. The ring light works without any camera access at all.
Optional preview. Camera permission is only requested if you click "Preview Lighting."
Local only. Your camera preview stays in your browser. Nothing is uploaded, recorded or transmitted.

What Is a Virtual Ring Light?
A virtual ring light is a browser-based tool that uses your existing screen as a light source. Instead of purchasing a physical LED ring light, you display a bright circular pattern directly on your monitor or phone screen. The screen illuminates your face from the front, reproducing the key visual effect of a conventional ring light: even, shadow-reducing frontal lighting.
The term covers several related approaches. Some users display a plain bright screen. Others use a circular ring pattern to leave the center dark, allowing a webcam positioned behind the screen to look through. This tool provides both options: ring mode (hollow center) and fill mode (solid bright surface).
Because no hardware is needed, a free virtual ring light online is useful whenever you need a quick improvement to your video call lighting, your selfie quality, or your streaming setup without carrying or setting up additional equipment.
How Does a Virtual Ring Light Work?
Your screen produces light. Every pixel on an LCD, OLED or AMOLED display emits or transmits light. When many pixels display white or near-white at high brightness, the screen becomes a usable front light source for webcams and cameras.
The tool controls what your screen displays: a circular ring, a filled ellipse, or a customizable combination. By adjusting the color of the pixels, the tool changes the apparent color temperature of the light falling on your face. Warm amber hues correspond to lower Kelvin values; neutral or slightly blue-white hues correspond to higher values.
Softness controls the edge gradient of the ring. A hard edge produces a more defined ring shape. A soft edge creates a smoother falloff, which typically looks more flattering in camera. The center opening keeps the area directly in front of your webcam lens dark so the lens does not reflect the screen and you can see clearly through to your subject.
Screen-based lighting works best when the screen is close to the subject. The inverse square law applies: a screen twice as close delivers roughly four times the light intensity. For best results, position the screen at arm's length or closer.
How to Use Your Screen as a Ring Light
- Step 1: Open the tool in your browser. Navigate to this page on the device you want to use as the light source. For best results, use your largest available screen: a desktop monitor or large laptop.
- Step 2: Choose a preset or configure manually. For most video calls, the "Video Call" or "Daylight" preset works well. For selfies, try "Soft Warm" or "Natural." Adjust brightness and color temperature to suit your environment.
- Step 3: Position your screen correctly. Place the screen directly in front of you at eye level. Your webcam or phone camera should be at the center of the ring or just above the top edge. Closer is better for brightness.
- Step 4: Enter fullscreen mode. Press F or tap the Fullscreen button to maximize the usable screen area. More screen surface means more light output.
- Step 5: Start your call or open your camera app. Use a separate device for your camera if possible. Open Zoom, Google Meet, Teams, FaceTime or your camera app. The ring light screen illuminates you while your camera captures the result.
- Step 6: Adjust to remove reflections. If your glasses reflect the screen, tilt the screen slightly upward or downward. Increasing softness or reducing ring width can also reduce the sharpness of the reflection.
Virtual Ring Light for Video Calls
Poor lighting is one of the most common problems in video meetings. A virtual ring light is a quick, hardware-free improvement. The ring light operates as a separate light source and does not require integration with Zoom, Google Meet or Microsoft Teams. It simply provides improved front illumination that your camera picks up automatically.
Zoom
Open the virtual ring light in a browser window and set it to fullscreen on your main monitor or a secondary screen. Start your Zoom call on a separate device or in a split-screen configuration. Zoom's built-in video enhancement can be used alongside the ring light for additional background blur.
Recommended: "Video Call" or "Daylight" preset.
Google Meet
The virtual ring light works the same way with Google Meet. For laptop users, open the ring light on the laptop screen and join the Meet call from a tablet or phone propped next to it. Google Meet's visual effects remain available and work alongside the external light source.
Recommended: "Daylight" or "Neutral" preset.
Microsoft Teams
If you have a dual-monitor setup, dedicate one monitor to the virtual ring light and run Teams on the other. On a single-screen setup, use the ring light on a separate phone or tablet screen positioned near your webcam. Teams' background effects remain available.
Recommended: "Video Call" or "Cool" preset.
FaceTime
On an iPhone or iPad, open the virtual ring light in Safari and switch to FaceTime for the call. On a Mac, run the ring light on a secondary screen while FaceTime runs on the main screen with your webcam facing you.
Webex
Cisco Webex benefits from improved front lighting in the same way as any other video platform. Run the virtual ring light fullscreen on a screen near your camera before or during Webex meetings for a quick improvement to video quality.
Webcam Lighting
Webcam sensors are typically small and sensitive to harsh or uneven lighting. Front-facing screen light provides an even source that reduces the contrast between highlights and shadows on your face, helping the webcam sensor expose correctly without blowing out highlights.
For webcam lighting, place the screen as close to the camera axis as possible. The ring light effect on webcam (the circular catchlight in the eyes) appears when the webcam is positioned at or near the center of the ring, which is visually distinctive and generally considered flattering.
If your room has strong ambient light from the side or behind, the screen-based light may not dominate the scene. In this case, dim or block background light sources and increase screen brightness for a stronger result.
Streaming and Recording
Screen-based ring lighting can improve a streaming setup when dedicated lighting is not available. For streaming and recording, a larger screen produces more usable light output. A 27-inch or larger monitor used as a ring light screen delivers noticeably more coverage than a 13-inch laptop screen at the same distance.
For OBS Studio or similar capture software, run the ring light tool in fullscreen on your lighting screen while the capture card or webcam faces you from the camera side. The ring light does not interact with OBS directly; it is simply your light source.
Recommended presets for streaming: "Studio" or "Streaming." The Studio preset uses a slightly higher temperature that cameras typically respond well to, while remaining visually comfortable for long sessions.
Selfies and Makeup
For selfies, hold the screen close and activate the front camera on a second device, or use the optional camera preview in this tool to see the effect in real time. Warmer presets (Golden Hour, Warm, Soft Warm) tend to produce more flattering selfie results because they reduce the visibility of blemishes under warm-toned light.
For makeup, accurate color is important. The "Daylight" or "Studio" preset provides a balanced, neutral white light that shows colors more accurately. This makes it easier to match foundation tones, assess eyeshadow color and verify the overall result before photographing.
Device-Specific Guides
The virtual ring light works in any modern browser. The core process is the same on all devices: open the tool, configure the light, go fullscreen, position the screen near your camera. The following notes cover device-specific differences in fullscreen behavior, brightness controls and camera positioning.
Windows
Open this tool in Chrome, Edge or Firefox. Press F11 to maximize the browser, then use the tool's Fullscreen button (or press F) to enter full-screen ring light mode. On a desktop with a secondary monitor, extend the display and drag the browser to the second screen for fullscreen ring light while your primary screen remains free for calls.
Mac / macOS
Open in Safari, Chrome or Firefox. The native Fullscreen API is supported on macOS. Use Mission Control or Spaces to keep the ring light on one space and your video call on another. Apple Silicon Macs with ProMotion displays can maintain very high peak brightness, improving light output.
Android
Open in Chrome for Android. Tap the Fullscreen button to enter immersive mode. Set screen brightness to maximum in your phone's settings. The tool activates Screen Wake Lock on Android Chrome to prevent the screen from turning off during use.
Samsung
Samsung Galaxy phones support this tool in Chrome or Samsung Internet. AMOLED displays on Galaxy devices can be very bright, improving ring light output. Turn off automatic brightness and set it to maximum manually. Some Galaxy models offer "Extra Brightness" mode (long-press the brightness slider) for additional output.
iPhone
Open in Safari on iPhone. iOS Safari has restrictions on the Fullscreen API for non-video elements. Use the "Add to Home Screen" option to install the tool as a PWA for a more fullscreen-like experience. Set screen brightness to maximum before use.
iPad
The iPad's larger screen makes it a more effective ring light source than a phone. Open the tool in Safari. The large screen surface provides more coverage and brighter illumination. Position the iPad on a stand at eye level near your camera for the best effect during FaceTime or other video calls.
Laptop
Using a laptop as a ring light is one of the most common use cases. The built-in webcam sits at the top center of the screen, which is near-ideal positioning. Set the tool to fullscreen, place the laptop directly in front of you, and use a phone or tablet for the actual video call to avoid the screen blocking the webcam view.
Desktop Monitor
A large desktop monitor is the most effective screen ring light. Larger screens deliver more light and a larger apparent source, producing softer shadows. Position the monitor directly in front of you and place your webcam at the top center. On a dual-monitor setup, dedicate the closer monitor to the ring light.
Chromebook
Chromebooks use Chrome OS and the Chrome browser natively. The Fullscreen API and local storage are fully supported. The tool can be installed as a PWA from Chrome on Chromebook. For Google Meet users (common on Chromebook), the ring light and Meet can run simultaneously using separate windows.
What Is the Ring Light Effect?
The ring light effect refers to the distinctive visual qualities produced by positioning a ring-shaped light source directly in front of a subject. The virtual ring light effect reproduces these qualities using your screen.
Because the light source surrounds the camera axis, shadows fall directly behind the subject and are mostly hidden from the camera's view. This produces unusually even, flat light that minimizes harsh shadows.
The circular light source reflects in the subject's eyes as a bright ring. This ring catchlight is visually associated with professional portrait and beauty photography and is widely considered a flattering, professional-looking feature.
Ring lighting is almost exclusively frontal. This differs fundamentally from side lighting or overhead lighting, both of which create more dramatic shadows. For video calls and portraits where the goal is clear, flattering representation, frontal ring lighting is a practical choice.
A virtual ring light effect reproduces these qualities using the screen as the light source. It is not identical to a physical LED ring light (which is brighter and more consistent in color), but it produces the same key effects: shadow reduction, frontal illumination and the characteristic catchlight, at zero hardware cost.

Lighting Tips
Temperature and skin tones: Color temperature around 5000K-5500K is close to neutral daylight and tends to render most skin tones accurately. Warmer temperatures (2700K-4000K) produce an amber cast that many find flattering, but this can affect color accuracy for makeup or product photography.
Reduce reflections in glasses: Tilt the ring light screen slightly upward or downward. Increasing softness or reducing ring width makes the reflected shape less distinct. Moving the screen slightly off-center can also shift the reflection out of the camera frame.
Avoid overexposure: If your camera's auto-exposure makes the background too bright, reduce brightness in the tool and let your camera expose naturally. Most webcams handle moderate screen light well without needing the tool at full brightness.
Dim background lights: A virtual ring light works best when competing light sources (windows, overhead lights) are dimmed or blocked. Front light from the screen is most effective when it dominates the scene.
Screen size and distance: Larger screens produce a larger apparent light source, making shadows softer. A large monitor at 50 cm is more flattering than a phone screen at the same distance. Move the screen closer to increase brightness rather than simply raising screen brightness, which can reduce battery life.
Ring mode vs fill mode: Ring mode leaves the center dark, allowing your webcam lens to record you without screen glare affecting the image. Fill mode is better for general illumination or selfies where the camera is positioned to the side.
