About the Lock black filled icon
This icon shows a classic padlock: a rounded U-shaped shackle sits above a square body with a keyhole cut into its center. It communicates security, privacy, protection and restricted access. Use it for login screens, password fields, privacy settings, security badges, checkout pages and account menus.
The shackle is drawn as a smooth arch and the keyhole combines a circle with a small trapezoid, giving the padlock a recognizable, legible shape at small sizes. It pairs well with key, shield and fingerprint icons in security UI. Works well as a status icon beside locked settings.
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.
