About the Padlock black outline icon
This icon draws a padlock in the closed position: a broad body that swells toward the base, a fixed shackle arching over the top, four small rivet circles near the corners and a classic keyhole with a round top and tapered slot at the centre. It communicates security, privacy and restricted access, so it fits login and password fields, privacy policy pages, encrypted content badges, locker and storage apps and account settings menus.
The silhouette is more antique than a modern rectangular lock, with soft shoulders and a heavy lower half that make it distinctive in a security set. The rivets and keyhole give an interior focal point that keeps the large body from looking empty. Use it with key, shield and fingerprint icons, and drop the rivets below 24 px.
This is the black outline version of the padlock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
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.
