About the Moon black outline icon
A waning crescent moon with a softly tapered tip sits centred inside a thin circular frame, leaving the crescent open rather than filled. It reads as night, dark mode, sleep and after-hours activity. Use it for theme switches in web and mobile apps, overnight weather forecast rows, bedtime and sleep-tracking screens, do-not-disturb settings and astronomy or calendar lunar phase displays.
The crescent is built from two offset arcs of unequal curvature so the horns stay pointed, and it occupies roughly two thirds of the enclosing ring, keeping breathing room on all sides. It pairs with sun, cloud, star and alarm icons in the same badged set. For a toggle, use it opposite the sun mark at matching optical size.
This is the black outline version of the moon icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
