About the Locked Treasure Chest black outline icon
A wide chest with a rounded barrel lid sits closed, banded by vertical straps at each corner and centered on a square lock plate with a clear keyhole. Nothing spills out, so it reads as a sealed reward waiting to be opened: loot, savings, hidden value or a locked achievement. Use it in game reward screens, loot box and daily bonus UI, savings and crypto wallet apps, pirate party graphics and puzzle or escape room branding.
The lid arc spans the full width above a straight horizontal band, giving the chest a stable, heavy proportion, and the lock plate is the only detail breaking the clean panel divisions. It pairs naturally with coin, key and gem icons in the same outline collection. Because the keyhole is small, avoid rendering below 20 px.
This is the black outline version of the locked treasure chest 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.
