Closed padlock with a rounded shackle and a keyhole in the body
About the Padlock black outline icon
A rectangular padlock body carries a centered keyhole made of a circle over a short tapered slot, topped by a tall semicircular shackle that is fully closed. It signals security, locked access, encryption and privacy. Use it for login and password fields, HTTPS and checkout trust badges, account privacy settings, locked content states and safety documentation.
The wide, almost square body and the generously arched shackle give the icon a sturdy, balanced silhouette, and the keyhole is large enough to survive scaling. It pairs with key, shield and unlocked padlock icons for on and off states. It stays legible down to 16 px in interface toolbars.
This is the black outline version of the padlock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
