LightScreen

LightScreen is a free, no-signup browser tool that turns any screen into a soft fill light or ring light. Open it on a laptop, monitor, tablet or phone, go fullscreen and adjust brightness and colour temperature to light your face for video calls, selfies, streaming, makeup or product photos in a dark room. It also offers plain white and solid colour screens for quick screen testing, such as checking for dead pixels, backlight bleed or uneven brightness. Nothing to install, no account and no watermark: it works instantly in any modern browser on desktop and mobile.

Remote workers on video calls, streamers, content creators, makeup and selfie users, and anyone needing a quick white or colour test screen.

Bad lighting makes people look dark and grainy on video calls and photos, and buying a ring light costs money and desk space. LightScreen turns the screen you already have into an adjustable fill or ring light instantly, for free, and doubles as a white/colour screen for display testing.
