Generate random noise and static images for testing, textures, and creative effects. Create classic TV static, smooth Perlin noise, film grain overlays, and more.
What is Noise/Static?
Digital noise consists of random variations in brightness and color. Static (TV snow) uses uniform random distribution, while Perlin noise provides smooth, natural-looking variations. These patterns are useful for testing, textures, and visual effects.
Why Use Noise Images?
Test image processing and compression algorithms with random data
Create texture overlays for film grain and vintage photo effects
Generate seamless tiling textures for games and 3D graphics
Test display quality and pixel response at various noise levels
Add organic imperfections to digital designs
Common Use Cases
Compression Testing
Noise images are difficult to compress, making them ideal for testing codec efficiency and image quality.
Film & Video Effects
Add film grain overlays to give digital footage a cinematic, analog appearance.
Game Development
Generate Perlin noise for terrain heightmaps, cloud textures, and procedural content.
Display Testing
Evaluate monitor pixel response, dead pixels, and color accuracy with random patterns.

Frequently Asked Questions
What is the difference between static and Perlin noise?
Static noise (TV snow) uses uniform random distribution where each pixel is independent. Perlin noise creates smooth, coherent variations that flow naturally between values, making it suitable for organic textures like clouds, terrain, and marble.
What density setting should I use?
For film grain effects, use 20-40% density. For testing or texture generation, 50% provides balanced noise. Use 80-100% for maximum random variation in compression testing or extreme visual effects.
How do I create a seamless tileable noise texture?
Use Perlin noise at power-of-2 dimensions (256×256, 512×512, 1024×1024). Perlin noise naturally tiles when generated at these sizes, making it ideal for game textures and repeating patterns.
What is the random seed used for?
The seed value initializes the random number generator. Using the same seed always produces the same noise pattern, allowing you to reproduce specific results or compare noise effects consistently.
Why are noise images hard to compress?
Compression algorithms work by finding patterns and redundancy in data. Random noise has no patterns, so each pixel must be stored individually. This makes noise images useful for testing maximum file sizes and codec limits.
