All pattern CSS is generated entirely in your browser. No input values or CSS output are sent to Sounez servers, and nothing is stored after you close the page.
CSS patterns work best for subtle geometric textures. For rich photographic textures, grain effects, or organic noise, use a real image file instead. CSS patterns also may not reproduce well in PDF exports or certain screenshot tools.
CSS patterns are significantly lighter than PNG or JPEG texture images — they add zero bytes to your page weight because the pattern is rendered by the browser from CSS rules. A PNG tile file of the same texture would typically be 2–20 KB.
Generate a second version of the pattern with inverted or adjusted colors for your dark theme. Use a CSS media query (prefers-color-scheme: dark) or a dark-mode class to switch between the two pattern CSS values.
No — these patterns are CSS-only, using inline SVG data URIs or gradient syntax. There is no PNG tile or external image file to host, which eliminates the extra network request and keeps your page fast.
