About the Attention Warning Triangle black outline icon

A triangle with softly rounded corners frames a tall exclamation mark: a tapering stroke above a separate round dot. It is the universal shape for caution, error and hazard, understood without any text. Use it for form validation messages, system error banners, safety instructions in manuals, machinery and chemical labeling, and road or worksite signage.

The triangle sits on a wide, stable base and the exclamation is centered with generous space on both sides, so the mark stays clear even when the shape is filled with a warning color. It pairs with info, error and success check icons. It works down to 16 px.

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