About Image Noise Generator
Add film-style grain or generate a standalone noise texture for backgrounds and overlays. Subtle noise reduces banding in gradients and gives flat designs a tactile feel.
How to use
- Upload an image to add noise, or start from a blank canvas.
- Adjust the noise amount and type.
- Download the result as a PNG.
Frequently asked questions
