Lock black filled icon
Solid padlock with a rounded shackle and a circular keyhole
About the Lock black filled icon
A closed padlock drawn as a solid rounded-square body with a thin arched shackle and a single ring keyhole punched out of the center. It signals security, privacy, restricted access and encrypted data. Use it on login and password fields, secure checkout and payment badges, privacy and permission settings, locked content or paywalls, and admin access controls.
The body is wide and low with generously rounded corners, and the keyhole is a plain circle rather than the usual keyhole-and-slot shape, which keeps it crisp when scaled down. Pair it with the unlocked, key and shield icons in the library. It stays readable to 16 px thanks to the solid fill.
This is the solid black filled version of the lock icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
