About the Key black filled icon
A classic door key sits inside a thin circular frame: a round bow with a hole at one end, a straight shaft, and a notched bit with three teeth angled at the tip. It reads as access, unlocking and security. Use it for login screens, password fields, account settings, real estate listings and hotel or rental booking pages.
The key runs diagonally across the circle, so the badge shape gives it an even margin on every side and suits round buttons or avatars. Pair it with padlock, shield and fingerprint icons; the enclosing ring means it needs no extra background circle.
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.
