Turns a browser tab into an adjustable, on-demand light source that projects a soft band of illumination onto your face, improving webcam appearance in meetings. Ringlight: ring light for video calls is made by alexandrebfaust as a Chrome extension and other Chromium browsers, and it activates automatically when a tab uses the camera. Its controls expose color temperature, shape, intensity, and special effects, so remote workers and students can fix poor room lighting without hardware.

How the extension integrates with web calls

Ringlight detects when a page accesses your webcam and can turn the virtual light on or off automatically, which removes a manual step during calls. The extension works with any site that uses the browser camera, including Google Meet, Microsoft Teams, and the web version of Zoom, so it directly targets browser-based conferencing workflows rather than system-wide camera feeds.

How far you can adjust the effect

The extension gives granular controls for light shape and intensity, including rectangle, oval, circle, and side bars, color temperature from 2000 K to 9000 K, thickness up to 1000px, opacity, and edge softness. Those settings let you tune the overlay to match room lighting or creative needs, and special modes like pulse and rotate change the overlay without editing camera settings.

Privacy and local settings storage

This extension uses a privacy-first design: there are no accounts, no tracking, and no network requests, and all settings stay on your device. The developer maintains an open-source Windows build on GitHub, and the Chrome extension does not send data externally, which suits users who want a local-only adjustment layer for their webcam image.

Layout considerations and UI impact

To prevent the overlay from hiding controls, Ringlight offers a Shrink the page mode that fits website content into the clear area of the ring light. That adjustment preserves call controls and buttons during meetings, while the Alt + Shift + L shortcut and toolbar toggle let you override automatic activation when you need the light off.

Good fit for browser-only lighting fixes, with a single-environment limit

Ringlight is a focused tool for people who take meetings in the browser and want quick, adjustable lighting without buying hardware. It keeps settings local and turns on with camera use, which suits privacy-minded users. The trade-off is the effect applies inside the browser tab only, so it doesn't change the image for native desktop apps or system camera feeds.
