About Add Noise

Add Noise applies a random film-grain effect to your image by adding random variation to each pixel's brightness, entirely in your browser. It's a single adjustable-intensity effect — not a choice of different noise types — and your image never leaves your device.

How to use Add Noise

  1. 1Click the upload area and select an image from your device.
  2. 2Adjust the intensity slider to control how much grain is added.
  3. 3Click 'Add Noise' to apply the effect.
  4. 4Click the download button to save your noisy PNG image.

Frequently Asked Questions

Is Add Noise completely free to use?

Yes, Add Noise is completely free with no watermarks or subscriptions required.

What image formats does Add Noise support?

It accepts common formats your browser can open, such as JPG, PNG, and WebP. The output is always a PNG file.

Can I choose between different noise types like Gaussian or salt-and-pepper?

No, there's a single grain effect with an adjustable intensity slider — no separate noise-type selector.

Is my image data secure and private?

Yes — everything happens locally in your browser. Your image is never uploaded to a server.

Tips & Tricks

  • ✓Start with a lower intensity and increase it gradually to find the right balance for your image.
  • ✓Add Noise works well on photos with good lighting and clear subjects, since grain can obscure fine detail on darker images.
  • ✓Re-upload your original image if you want to try a different intensity from scratch.
  • ✓Use a lighter touch on portraits and a heavier one on landscapes or artistic shots for a more dramatic effect.
