Image Noise Tool
Add adjustable grain or digital noise to photos and graphics directly in your browser.
Add Grain or Noise to an Image
The tool introduces random brightness variation across RGB pixels to create anything from subtle texture to a strong grain effect.
Example
A smooth social graphic adjusted to 15% noise can gain a light film-like texture without changing its dimensions.
Factors That Affect the Result
Higher noise amounts create more visible variation. Fine-detail images can become visually busy at strong settings, while flat gradients often show the effect clearly. Each render uses random values, so repeated results can differ slightly.
Frequently Asked Questions
Is noise the same as blur?
No. Noise adds variation; blur smooths detail.
Does noise resize the image?
No. Dimensions remain unchanged.
Is processing local?
Yes. The effect runs in your browser.

Adding Image Noise
Noise adds random grain to an image and can create texture or a film-like effect. Small amounts may reduce an overly digital look, while heavy noise can hide detail and increase file complexity. Review smooth areas such as skies and skin carefully, since artifacts are most noticeable there.
Adding Image Noise
Noise or grain can create texture and reduce an overly smooth digital look. Use a light amount for subtle texture and stronger settings for a deliberate stylized effect. Because added noise can reduce apparent detail and increase compression artifacts, preview the image at its intended display size before saving.
Technical Method and Practical Limits
Adding synthetic image noise changes pixel values to create grain or texture. Noise amount and distribution affect the look, and strong noise can obscure fine detail or reduce compression efficiency in formats such as JPEG.
