About the Warning Triangle Exclamation black outline icon

An equilateral triangle with softly rounded corners frames a tapered exclamation mark that narrows toward its base, with a separate dot below. It is the universal caution signal for hazards, unsafe actions and system errors. Use it for form validation messages, destructive-action confirmation dialogs, browser and app error banners, machinery safety labels and road or workplace hazard signage.

The stroke weight stays even around the triangle, and the exclamation sits high and centered so negative space keeps it legible. The tapered stem is the detail that separates this version from a plain bar. It pairs with info, error and success circle icons in the same alert family. Reliable down to 16 px in toolbars.

This is the black outline version of the warning triangle exclamation 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.
