What Is a CSS Extractor?
HTML files often embed CSS in <style> tags or inline style attributes. A CSS extractor parses the HTML and pulls out all styles into a single CSS file. Useful for migrating embedded styles to external stylesheets, auditing what CSS a page uses, or converting scraped HTML to editable CSS. The HTML spec and CSS spec define the structure.
This tool runs in your browser. Paste HTML or upload a .html file. It extracts <style> block content and inline styles. Nothing is sent to a server. For formatting the output, use CSS Formatter. For combining multiple CSS files, use CSS Combiner.
How to Use This Tool
Paste or Upload HTML
Paste your HTML into the left editor or click Upload to load a .html or .htm file. Use Sample to load example HTML with embedded styles.
Review Extracted CSS
The right panel shows extracted CSS from <style> tags and inline styles. For validation, use CSS Validator. For minifying, use CSS Minifier.
Copy or Download
Use Copy or Download to save the CSS. For converting HTML to Markdown, use HTML to Markdown. For CSS to inline (email), use CSS to Inline.
Where CSS Extraction Helps
When migrating a legacy site or converting a single-file HTML document to a structured project, extracting CSS is the first step. Email templates, CMS exports, or scraped pages often have embedded styles. This tool gives you a starting point for refactoring. MDN HTML and MDN CSS document the standards.
For combining extracted CSS with other stylesheets, use CSS Combiner. For adding vendor prefixes, use CSS Prefixer. For converting preprocessors, use SCSS to CSS or Stylus to CSS.
Frequently Asked Questions
Is my data private?
Yes. Extraction runs entirely in your browser. No data is sent to any server.
Does it extract @import or linked CSS?
No. It extracts only <style> block content and inline style attributes. External stylesheets (@import or <link>) are not fetched or included.
What about inline styles?
Inline styles are extracted and wrapped in a comment for reference. They apply to specific elements, so the output may need manual adjustment for reuse.
Does it handle scoped styles?
Scoped styles (e.g., Vue scoped, Angular view encapsulation) are extracted as-is. The scope attributes may need to be considered when using the CSS elsewhere.
Can I extract from a URL?
This tool works with pasted or uploaded HTML. To extract from a URL, fetch the HTML elsewhere and paste it here.
