Closed padlock icon with arched shackle and a round keyhole on the body
About the Lock black filled icon
A padlock drawn in a closed state: a tall rounded shackle rises above a softly squared body, and a circular keyhole with a short vertical slot sits centered on the face. It reads instantly as security, privacy and restricted access. Common placements include login and password fields, HTTPS indicators in browser UI, secure checkout buttons, locked file or folder states and account privacy settings panels.
The body is slightly taller than wide with generous corner radii, and the shackle arc matches the body width so the silhouette stays balanced. It pairs naturally with unlock, key, shield and eye-off icons from the same set. At 16px, keep the keyhole as a simple dot so the interior does not fill in.
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.
