Turn your monitor or phone into a soft fill light for Zoom, Teams, Google Meet, and selfies. Adjust Kelvin color temperature, brightness, and ring-light mode — free, browser-based, no upload.
A screen fill light uses your display as a large, soft light source. Instead of buying a ring light, you open this tool, go fullscreen, and position the bright screen beside or in front of your face. The wide surface diffuses light evenly, filling shadows under your eyes and chin — the same principle as a softbox or ring light, but using hardware you already own.
Yes. This is a universal lighting tool — it does not integrate with any video app. You open the fill light on a second monitor, laptop, or tablet while your call runs on your primary screen. Any conferencing app (Zoom, Microsoft Teams, Google Meet, Discord, Skype) benefits from better frontal lighting without changing settings inside those apps.
For most video calls, 5000–5500K (neutral daylight) looks natural on camera. Warmer 3200–4000K flatters skin tones for selfies and evening calls. Cooler 6000K+ can look clinical. Use the Video call preset (5500K) as a starting point, then adjust if your room lighting is very warm (incandescent) or cool (fluorescent).
Start at 70–85% for video calls in a normally lit room. In a dark room, 40–60% is often enough and reduces eye strain. Avoid 100% for long sessions — especially on OLED displays. Scroll over the preview or use the slider to fine-tune. If your face looks overexposed on camera, lower brightness; if you still look shadowy, raise it slightly.
A second screen gives the best results: place it 2–3 feet away at 30–45° beside your webcam, slightly above eye level. You can also use a phone or tablet as a portable fill light — tablets work well because of their larger surface. A single laptop screen works in a pinch, but position it off-angle so glare does not reflect into the webcam lens.
No. All color calculations run locally in your browser. There is no login, no file upload, and no server processing. The tool only renders a colored fullscreen surface on your device.
Ring light mode displays a bright circular band on screen, simulating the catchlight pattern of a physical ring light visible in eyes during professional portraits. Flat mode fills the entire screen for maximum diffuse output. Use flat mode for brightest fill; use ring mode when you want the characteristic ring-shaped highlight in reflective surfaces or creative shots.
