About this fractal generator
This fractal generator renders four classic fractals on an HTML canvas: the Mandelbrot set, the Julia set, the Sierpinski triangle, and the Koch snowflake. For the escape-time fractals you can raise the iteration count and zoom to reveal finer structure and shift the color hue, while the geometric fractals expose a recursion-depth control and a color picker. When you like the result, download it as a PNG. All rendering happens locally with plain canvas math, with sensible caps on iterations and depth so the page stays responsive, and no image is ever uploaded.
