CSS to Tailwind Converter

ExtractCSS offers the most advanced CSS to Tailwind converter available online. Paste your HTML and CSS, and get clean Tailwind utility classes in seconds. The converter handles CSS variables, media queries, pseudo-classes, specificity resolution, and modern color formats.

What Makes This Converter Different

• ✓ Smart Value Snapping - CSS values snap to the nearest Tailwind design token. A computed #3b82f6 becomes blue-500.
• ✓ CSS Normalization - Shorthand properties are expanded, cascade conflicts resolved, and browser defaults stripped.
• ✓ Modern CSS Support - Handles CSS variables, oklch colors, container queries, and nesting.
• ✓ Specificity Engine - Competing declarations are resolved by specificity and media context, just like the browser.
• ✓ Preflight Optimization - Browser default styles are automatically removed, so you only get meaningful Tailwind classes.

How It Works

1. Paste your HTML and CSS into the editor panels.
2. The converter parses your CSS through a full PostCSS pipeline.
3. CSS values are matched to Tailwind design tokens with configurable tolerance.
4. Copy the output - clean HTML with Tailwind utility classes.
