Transform black SVG icons and images into exact target Hex colors using CSS filter matrix rules.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Pick or enter any Hex color code (e.g. #3b82f6).
Verify the side-by-side match between raw CSS background and filtered SVG icon.
Copy the computed CSS filter string directly into your stylesheet.
CSS filters allow you to colorize external <img> tags or CSS background-image SVGs where inline SVG 'fill' cannot be accessed via CSS.
The CSS filter algorithm expects a pure black (#000000) base SVG icon to calculate accurate inversion and hue rotation.
