Film grain and color noise
Monochrome noise adds the same random value to all channels (classic film grain); color noise adds independent random values per channel for a chromatic effect.

Frequently asked questions
What is the difference between monochrome and color noise?
Monochrome noise adds the same random delta to all three color channels, giving a neutral gray grain like classic film. Color noise adds different random values to each channel, producing a chromatic, multicolor speckle.
Is the noise tool free?
Yes — completely free and unlimited. No signup, no account, no watermark, no daily limit.
Are my files uploaded to a server?
No. The noise is added entirely in your browser on your device. Your image never leaves your computer, so it stays fully private.
Can I use it to fix banding in gradients?
Yes — a small amount of noise (5–10%) can break up visible color banding in flat-color gradients, a technique called dithering.
