Outline closed padlock with round keyhole, enclosed in a circular badge frame
About the Lock black filled icon
A closed padlock sits centered inside a thin circular frame. The body is a rounded rectangle carrying a small round keyhole with a short vertical slot below it, and a tall U-shaped shackle rises from the top. The circle turns it into a badge, which suits secure checkout seals, HTTPS and SSL notices, login and password fields, privacy settings rows and data-protection slides.
The shackle is drawn in double lines so it reads as a solid loop, and the keyhole is placed slightly above center for visual balance inside the circle. It pairs naturally with unlocked padlock, key, shield and fingerprint icons. Because of the outer ring, give it a little more room than a bare padlock at small sizes.
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.
