About the Key black filled icon
A single door key stands upright: a large circular bow with a small hole at its center forms the base, a slim straight shank runs up the middle, and the tip is cut into three squared notches on one side. It signals access, permission, unlocking and ownership, which makes it a natural fit for login and password fields, API key settings, hotel and rental listings, locksmith services and membership or premium unlock states.
The round bow carries most of the visual weight at the bottom, balancing the thin shank so the shape stays stable at small sizes, and the stepped teeth give it a recognizable silhouette in a toolbar. Pair it with padlock, shield and fingerprint icons in a security set, and render it at 24px or larger so the notches survive.
This is the solid black filled version of the key 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.
