Unlock black outline icon
Open padlock inside a circle with the shackle lifted aside and short burst lines beside it
About the Unlock black outline icon
An open padlock inside a thin circle, its shackle swung up and away from the body while three short lines burst from the side to show the moment it springs open. A keyhole sits centered on the square case. Use it for login and sign-out states, permission toggles, unlocked premium features, password reset flows and privacy settings.
The body is a rounded square with a single keyhole; the tilted shackle and motion strokes are what separate it from the locked variant. Ship both together so the state change reads instantly. Keep the burst lines at full stroke weight when scaling below 24 px.
This is the black outline version of the unlock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
Download it free as a scalable SVG vector or transparent-background PNG in seven sizes (16 to 512px), copy the SVG code straight into your project, or open it in the free online editor to change colors, apply gold, silver, neon and gradient styles, animate it, or convert it to EPS, PDF and DXF.
