A free online Sierpinski triangle generator that creates stunning fractal patterns. Customize recursion depth (1-8), choose two gradient colors, and watch the fractal self-similarity emerge. Download your fractal as a PNG image. A mesmerizing visualization of mathematical recursion.
Adjust the recursion depth slider (higher = more detail).
Choose two colors for the gradient fill.
The fractal automatically renders with your settings.

The Sierpinski triangle is a fractal shape where an equilateral triangle is recursively subdivided into smaller equilateral triangles, creating a self-similar pattern.
You can set the recursion depth from 1 to 8. Higher depths create more detailed fractals but require more computation.
