Frequently Asked Questions

A CSS noise texture is a grainy or turbulent pattern generated using CSS and inline SVG, without external image files. It uses <feTurbulence> to create procedural noise, then converts it into a base64 data URI that you can paste directly into your stylesheet.

You choose frequency, opacity, noise type and a background color – the tool builds a tiny SVG filter, encodes it as a data URL, and shows a live preview. The resulting CSS is ready to copy and use.

Yes! The background image is a base64-encoded SVG, which is still considered “pure CSS” because it lives entirely inside your stylesheet. No HTTP requests, no external files.

All modern browsers fully support SVG data URIs and feTurbulence – Chrome, Firefox, Safari, Edge and even mobile browsers. IE11 has partial support, but a simple fallback background-color works fine.

Copy the generated CSS block and paste it into your stylesheet or a <style> tag. Then add the class .noise-texture to any HTML element (e.g. <div class="noise-texture">). You can also rename the class as needed.

fractalNoise produces a smooth, cloud-like texture (good for subtle grain). Turbulence gives sharper, more chaotic noise – perfect for TV static, grunge, or aggressive grain.

Absolutely. The noise itself is grayscale. Use the background color picker and blend mode dropdown to tint the noise. For example, a dark-red background with screen blending creates a red-tinted noise.

No extra HTTP requests, infinite resolution (vector-based), tiny file size, fully customizable on the fly, and no compression artifacts. Perfect for subtle grain overlays, vintage effects, or adding texture to UI backgrounds.
