Noise Texture

Generate film-grain PNGs โ€” transparent overlays that kill colour banding.

About this generator

Fresh random noise at useful sizes โ€” small tileable squares up to a full-HD overlay โ€” with intensity and grain-size controls, monochrome or RGB, and a transparent mode built for layering. Every click of regenerate is a new texture.

Why designers keep reaching for noise

Two honest jobs. First, banding: smooth digital gradients show visible stripes where 8-bit colour runs out of in-between values, and a whisper of noise breaks the stripes up โ€” the eye forgives grain far more readily than bands, which is why subtle noise hides in most polished gradient backgrounds (it's the same trick dithering performs at the extreme). Second, warmth: film grain says โ€œphotographโ€ the way vignetting says โ€œlook hereโ€ โ€” a low-opacity grain layer over flat digital art reads instantly more organic, the moody-landing-page standard. The transparent mode carries its intensity in the alpha channel, so it drops over anything as a finished overlay; the solid mode suits blend-mode workflows in editors. Square sizes tile acceptably because noise hides its own seams โ€” one 512 square can paper a wall. Grain size 1 is fine film; 3โ€“4 is chunky retro. The gradient underneath is the CSS gradient tool's job, and How random is a random number generator? is the story of the randomness itself.

Frequently asked questions

How do I use this over a gradient?

Generate transparent monochrome noise at 10โ€“20% intensity and layer the PNG on top โ€” in CSS as a second background-image, or as a layer in any editor. Banding disappears, warmth appears.

What intensity should I use?

10โ€“20% for invisible banding-repair, 25โ€“40% for visible film grain, more only for deliberate static effects. If you notice the noise before the image, go lower.

Do the square sizes really tile?

Well enough โ€” random noise has no pattern to break at the seams, so repeating a 256 or 512 square reads as continuous texture in backgrounds.

Monochrome or RGB?

Monochrome for film grain and banding repair (colour noise reads as broken TV). RGB static is its own aesthetic โ€” glitch art and retro screens.
