Noise Texture Generator

This noise texture generator creates procedural noise textures right in your browser, with six algorithms to choose from: Perlin, Simplex, Worley (cellular), Fractal Brownian Motion (FBM), Turbulence, and White noise. Adjust the look with live sliders and download the result instantly.

The output is perfect for subtle website backgrounds, game surfaces and terrain, film-grain overlays, paper and marble effects, and generative art. Turn on seamless tiling and the pattern repeats edge to edge with no visible seams. It is built for web designers, game developers, graphic designers, and digital artists who want a quick, customizable source of grain and pattern.

Private by design: every texture is generated locally on your device. Nothing is uploaded to a server, and no images or usage data are collected.

How to Use

Pick a noise type

Choose your algorithm from the Noise Type panel — Perlin, Simplex, Worley, FBM, Turbulence, or White — or click a Preset like Film Grain, Clouds, or Marble to start from a tuned look.

Adjust the parameters

Drag the Scale, Octaves, Persistence, and Lacunarity sliders to shape the pattern. Fine-tune Contrast and Brightness, or flip light and dark with Invert. The preview updates live.

Choose colors and tiling

Set the Color Mode to Grayscale, Two Tone, or a four-color Palette. Enable Seamless Tile, then switch to the Tiled 2×2 view to confirm the edges blend without seams.

Set size and download

Pick an output Size (256, 512, 1024, or 2048) and a Format (PNG, JPG, or WebP), then click Download to save the texture to your device.

Each texture is determined by its Seed, so noting the seed lets you recreate the exact same pattern later. Use the Random Seed button to roll a new one, or Randomize to shuffle every parameter at once.

Features

Six Noise Algorithms

Generate Perlin, Simplex, Worley (cellular), FBM, Turbulence, and White noise to cover smooth gradients, cells, marble, and grain.

Eight One-Click Presets

Film Grain, Clouds, Marble, Paper, Organic, Static TV, Cells, and Wood load tuned settings you can fine-tune further.

Adjustable Parameters

Control Scale, Octaves, Persistence, and Lacunarity to dial in zoom level and fractal detail for any pattern.

Seed Control

Every texture is reproducible from its seed value, so you can recreate or share an exact pattern, or roll a random one.

Three Color Modes

Keep classic Grayscale, blend a Two Tone gradient between two colors, or map noise across a four-color Palette.

Contrast, Brightness & Invert

Push contrast and brightness for the exact look, then flip light and dark values with a single Invert toggle.

Seamless Tiling & 2×2 Preview

Generate edge-to-edge tileable textures and verify them in a Tiled 2×2 view before downloading.

Sizes & Formats

Export square textures at 256, 512, 1024, or 2048 pixels as PNG, JPG, or WebP.

Randomize Everything

Hit Randomize to shuffle the noise type and all parameters at once and discover unexpected patterns.

Runs in Your Browser

All rendering happens on your device with no uploads, so your textures stay private and generation is instant.

Frequently Asked Questions

What is a noise texture?

A noise texture is an image built by a mathematical algorithm that produces random or pseudo-random patterns. Designers and developers use these textures for backgrounds, terrain generation, film grain, and other visual effects in design, games, and digital art.

What is the difference between Perlin and Simplex noise?

Both produce smooth, gradient-based noise. Simplex is an improvement on Perlin with fewer directional artifacts — it avoids the grid-aligned patterns Perlin can show — and slightly better performance. For most textures the two look very similar, so it is worth trying both.

How do I make a seamless noise texture?

Turn on Seamless Tile in the Output section, then switch to the Tiled 2×2 view to check that the left edge matches the right and the top matches the bottom. When the seams disappear, download the texture and it will repeat cleanly as a background.

What do Octaves, Persistence, and Lacunarity control?

Octaves set how many layers of noise are combined — more octaves add finer detail. Persistence controls how much each successive octave contributes, where lower values give a smoother result. Lacunarity sets the frequency increase between octaves, so higher values add more detail variation. These apply to the fractal types and are hidden for White noise.

Why does the same Seed always produce the same texture?

The seed initializes the random number generator behind the noise algorithm. Using the same seed with the same parameters always produces identical output, which makes it easy to reproduce a texture later or share the exact pattern with someone else.

What size and format should I export?

512×512 is a solid default for web backgrounds; use 256 for smaller, faster-loading textures and 1024 or 2048 for high-resolution screens or print. For format, PNG is lossless and best for sharp detail, JPG is smaller with some compression, and WebP balances quality and file size for modern browsers.

Are my generated textures private?

Yes. Every texture is generated locally in your browser and the download is created on your device — nothing is sent to a server, and no images or usage data are collected.
