Website Design System Extractor

What this tool does

Paste any URL and extract the full design system behind it. Get the color palette (grouped by primary, neutral, accent), every font with weights and source links, the spacing scale, border radii, and box shadows — all in one scan. Export as CSS custom properties, a Tailwind config, or raw JSON. Perfect for reverse-engineering a site's design tokens, building a mood board, or bootstrapping a new project from a design you admire.

Frequently asked questions

How do I extract a design system from a website?

Paste the website URL into our design system extractor and click "Extract." The tool fetches the page and all linked stylesheets, then pulls out every color, font, spacing value, border radius, and box shadow it finds. Results are organized into categories and exportable as CSS variables, Tailwind config, or JSON.

Can I use this instead of a "website to Figma" converter?

This tool extracts design tokens (colors, fonts, spacing) — the reusable building blocks of a design system. Unlike full-page converters that produce messy auto-layouts, these tokens are what designers actually reuse. Import the CSS variables or JSON into Figma as color/text styles for a much cleaner result.

What export formats are available?

Three formats: CSS custom properties (paste into your :root), Tailwind config (extend your theme), and raw JSON (for any tool or workflow). Each includes all colors, fonts, spacing, radii, and shadows.

Does it extract spacing and layout values?

Yes. The tool scans for padding, margin, gap, border-radius, and box-shadow values across all stylesheets. Spacing values are shown as a scale sorted by size, and only values used more than once are included to filter out one-off pixel values.

Why are colors grouped into categories?

Colors are automatically categorized as Primary (high saturation, likely brand colors), Neutral (low saturation grays and near-whites), or Accent (medium saturation supporting colors). This helps you understand the color hierarchy of the design system at a glance.

Can I extract design tokens without installing a browser extension?

Yes. This tool runs entirely online — paste a URL and get results. No extension, no sign-up, no downloads. For ongoing use with saving and organizing, install the PocketUI extension.
