About Image Noise Generator
The Procedural Film Grain & Digital Noise Generator adds authentic film grain textures (Gaussian, Uniform, Perlin, Salt & Pepper) to digital images, eliminating color banding in gradients and adding cinematic analog warmth.
How to Use Image Noise Generator
Step 1
Upload your image or generate a standalone transparent noise texture overlay.
Step 2
Select noise distribution type and adjust Noise Amount slider (1% to 100%).
Step 3
Toggle Monochromatic mode for classic film grain look.
Step 4
Click "Download Image" or "Copy Noise Texture".
Practical Use Cases for Image Noise Generator
Eliminating Gradient Banding on Digital Artwork
Add 1-3% subtle Gaussian film noise to smooth CSS gradients and illustrations to completely eliminate color step banding on 8-bit displays.
Simulating 35mm Analog Film Grain for Photography
Add organic grain texture simulating classic Kodak Tri-X or Fujifilm 400 film stocks to modern ultra-clean digital photos.

Key Terminology & Definitions
Gaussian Noise
Statistical noise having a probability density function equal to that of the normal distribution, closely mimicking organic photographic film grain.
Dithering / De-Banding
Using subtle micro-noise to break up quantization steps and smooth out harsh banding artifacts in digital color gradients.
