About this tool
Generates procedural noise textures (Perlin or Simplex) with adjustable parameters: octaves, scale, and seed. Downloadable as PNG. Useful for background textures in design, terrain in games, height maps, organic patterns for print, and as a base for visual effects that need natural variation.
How to use
- Pick the noise type (Perlin or Simplex).
- Adjust octaves to set detail level and scale for pattern size.
- Set a seed for reproducibility or leave it random.
- Download the image as PNG.
Frequently asked questions
- What's the difference between Perlin and Simplex?
- Both produce smooth, continuous noise without the grainy look of purely random noise. Simplex was developed after Perlin to be faster in higher dimensions and to produce fewer axis-aligned visual artefacts. In 2D the difference is subtle. Try both and pick whichever looks better for your use.
- What are octaves?
- Layers of noise stacked with different frequencies and amplitudes. More octaves add fine detail on top of the base pattern, creating a richer texture with more variation. Too many octaves make the texture grainy. Start with 3 or 4 and adjust to taste.
- What is the seed for?
- The seed determines the exact pattern generated. Using the same seed with the same parameters always gives the same texture. Useful for reproducing a result you liked, sharing it with collaborators, or making variations of the same base pattern.
