Closed padlock with arched shackle and a keyhole on the body
About the Lock color outline icon
A closed padlock drawn with a tall arched shackle sitting on a rounded square body, with a classic keyhole shape centered on the face. It reads instantly as security, privacy and restricted access, which makes it useful for login and password fields, secure checkout badges, encrypted file markers, VPN and antivirus dashboards, and privacy policy pages where a small trust cue matters.
The composition is vertical: the shackle occupies the top third and the body the lower two thirds, with even stroke weight and generous corner radii. It pairs naturally with key, shield, fingerprint and unlocked padlock icons from the library. Keep it at 24px or larger so the keyhole stays legible in form fields.
This is the colour outline version of the lock icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
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.
