Lock black filled icon
Closed padlock with arched shackle and a round keyhole with a slot on its square body
About the Lock black filled icon
A padlock is shown closed, its arched shackle seated on a square body with rounded corners, and a keyhole formed by a small circle and a short vertical slot at the center. It stands for security, privacy and restricted access. Fits login screens, password fields, privacy settings, HTTPS and encryption badges, and locked content in dashboards.
The body is nearly square and the shackle rises about half its height, giving a compact silhouette that holds up at 16 px. It pairs with unlock, key, shield and eye icons in the same set. Use the filled variant when the lock must read as a status badge.
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.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
