Alert Warning Triangle black filled icon

About the Alert Warning Triangle black filled icon

The icon shows a rounded triangle with a double outline containing a centered exclamation mark and dot, the universal caution symbol. It suits error and validation messages, safety and hazard notices, system status alerts and notification banners across apps and dashboards.

The double border adds visual weight so the shape reads clearly as a warning even at small sizes, while the exclamation stays simple and bold. It pairs with notification, danger and shield icons in the library. Use it at 20px+ so the inner and outer triangle lines don't merge.

This is the solid black filled version of the alert warning triangle icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.

Download it free as a scalable SVG vector or transparent-background PNG in seven sizes (16 to 512px), copy the SVG code straight into your project, or open it in the free online editor to change colors, apply gold, silver, neon and gradient styles, animate it, or convert it to EPS, PDF and DXF.
