Moon Icon Generator

What the moon icon means

Dark mode, night or sleep. The crescent is unambiguous and works even without any surrounding context.

Weather icons have a second life as interface controls: the sun and moon now mean light and dark theme far more often than they mean day and night. Both are excellent app icon shapes — a disc with rays and a crescent are simple, solid and instantly readable. The rest of the class is more fragile, since rain, snow and wind are all drawn with thin repeated strokes that merge into grey texture below about 24 pixels.

Where you will actually see it

• dark mode toggles
• do-not-disturb and sleep modes
• app icons for sleep and night-shift apps

Drawing the moon at 16 pixels

The crescent thins to a hairline at its tips. Thicken the crescent overall — a fatter moon is more legible.

Stroke weight is the control that matters most here. Lucide icons are drawn on a 24 × 24 grid with a 2px stroke, which means that when the icon is scaled down to 16px the stroke is effectively 1.33px — below one device pixel on a standard-density display. Raising the stroke to 2.5 or 3 before exporting keeps the shape solid; lowering it to 1.5 suits large app icons where a heavy stroke looks clumsy. The editor exposes this as a slider, so you can find the value that survives your smallest target size rather than guessing.

Using it in code

If you want the icon in a Vue project rather than as a downloaded asset, it is a named export of the lucide package:

import { Moon } from 'lucide-vue-next'

<Moon :size="24" :stroke-width="2" />

The download button above gives you something different: the icon composed onto a background with a corner radius, exported as a flat SVG path set. The exporter converts the icon out of its <foreignObject> wrapper first, because a foreign object taints an HTML canvas and would otherwise break PNG and ICO rasterisation.
