Website CSS and Style Extractor

About

Website CSS and Style Extractor is a design-system inspection tool for designers and developers. Open any webpage, click the extension, and see the styling that makes the page look the way it does — every color, font, size, weight, spacing value, border-radius, shadow and CSS custom property — ranked by how often the site uses it.

Then save the result in whatever format your workflow prefers.

What you get

- Colors — every unique color on the page, deduplicated and ranked by frequency. Click any swatch to copy its value.
- Typography — font families, sizes, weights and line heights, each with usage counts.
- Spacing — margin/padding scale, border-radius values, box shadows.
- Tokens — all CSS custom properties defined on the document root.
- Element picker — click any element on the page to capture its grouped computed styles.
- Raw stylesheet dump — full contents of every readable stylesheet.

Export options

- JSON — the complete dataset, machine-readable
- CSS design tokens — custom properties for your own stylesheet
- SCSS variables — for Sass projects
- Utility-framework config snippet — a drop-in theme extension
- Markdown report — documentation-ready
- Standalone HTML style guide — a shareable, printable page
- Raw CSS dump — every readable stylesheet concatenated
- Bundle — all of the above in one file

Privacy

The extension does not collect, transmit or share any data. Everything happens locally in your browser. It makes no network requests and only reads styling information from the tab you are currently viewing, and only when you click the toolbar icon.

Who it is for

- Designers auditing an existing brand or a competitor site
- Front-end developers migrating legacy stylesheets to a token system
- Agencies documenting a client's current design
- Anyone curious about how a site was built
