Lock black filled icon
Outline padlock with rounded shackle and a keyhole in the center of the body
About the Lock black filled icon
A closed padlock stands upright: a squat rectangular body with a small keyhole at its center and a smooth arched shackle rising from the top. It reads instantly as protection, privacy and restricted access. Use it on password fields, HTTPS badges, locked settings, private album toggles, and security sections of dashboards or landing pages.
The body is wider than it is tall, giving the shackle room to arc cleanly, and the keyhole keeps its shape down to 16 px. Pair it with the unlocked variant, a key and a shield from the same set; place it inline beside form labels.
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.
