Add Noise to Image

Drop your photos in, pick a noise type and strength. The result appears right away, and a slider over the image shows the before and after.

Types of noise

• Film grain. Monochrome grain that shows in the midtones and nearly disappears in deep shadows and clean white, the way film photos look.
• Monochrome. The same grain at even strength across the whole frame.
• Color. Each color channel gets its own noise, like a shot taken at high ISO.
• Salt and pepper. Scattered pixels turn black or white.

Grain size and softness

Size 1 puts noise in every single pixel, while larger sizes form chunky clusters. Softness blurs the edges of the grain. After the blur, the noise is brought back to the chosen strength, so soft grain does not look washed out. Fine grain is less visible in the small preview than in the finished file.

Consistent noise pattern

The noise pattern depends on the image's name and size, so the preview and the downloaded file match, and running the same image through again produces the same pattern. If you need noise so a platform will not recognize the image as a duplicate, try the image uniquifier: it alters an image in several ways at once.
