CSS Noise Grain Overlay
Generate SVG noise overlay CSS for subtle grain texture.
Add subtle grain texture
A faint noise or grain overlay adds warmth and depth to flat backgrounds and gradients, softening the digital-perfect look. This generator produces an SVG-noise overlay as a CSS background so you can layer texture without an image file.
Because the noise is generated as an inline SVG, there is no extra asset to load and the intensity is easy to tune. Adjust the opacity and scale, then copy the CSS to layer a tasteful grain over any surface.
Copy-ready CSS
The CSS is generated live in your browser as you adjust the controls, so there is nothing to install and nothing is uploaded. Copy the ready-to-use declaration straight into your stylesheet, tweak the values to taste, and it will render exactly as it does in the preview here.
