Sleep black filled icon
Crescent moon with three Z letters inside a circle representing sleep
About the Sleep black filled icon
A circular frame holds a thick crescent moon on the left while three Z letters step diagonally down beside it, decreasing in size as they fall. The pairing is the universal shorthand for sleeping, napping and night mode, so it suits alarm and bedtime apps, sleep tracking dashboards, hotel booking amenities, do-not-disturb toggles and hospital or clinic wayfinding.
The crescent's inner curve leaves room for the Zs, so both elements read clearly without overlapping, and the diagonal of the letters adds movement to an otherwise static badge. It matches the sun, alarm clock and bed icons in the same circular family. Keep it 32 px or larger so the smallest Z holds shape.
This is the solid black filled version of the sleep icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
