Website CSS Extractor

Collect the CSS behind a page. The extractor lists the linked stylesheets with their media type, counts style blocks and style attributes, then fetches up to eight stylesheets and shows the size and number of rules of each. All CSS – fetched files and inline style blocks – is combined into one text you can copy or download as styles.css. @import rules in inline CSS are flagged because they load files one after another.

CSS and page speed

Browsers wait for stylesheets before painting the page. Large or many stylesheets delay the first view, which is why critical CSS and fewer files help.

Rule counts reveal frameworks that ship far more styles than a page uses.

How it works: our server downloads the page once through a guarded fetcher that only connects to public addresses, follows a limited number of redirects and stops after a size and time limit. The HTML is then analysed in your browser as inert text – scripts on the page never run and nothing is stored.

What it cannot see: content and resources that a page adds with JavaScript after it loads, pages behind a login, and servers that block automated requests. For those, open the page in your browser, use its developer tools, or paste the page source where the tool offers a paste option.

Use the results as a starting point: fix the items marked red first, review the yellow warnings in context, and run the check again after a change. Requests are rate-limited to keep the service fair; if you check many pages in a row, wait a few minutes.

Related checks on this site cover the rest of a technical review – speed and Core Web Vitals, security headers, structured data, accessibility and SEO signals – so you can work through a whole site audit one topic at a time.

Who it is for: site owners checking their own pages, developers debugging a release, SEO and marketing teams auditing clients or competitors, and students learning how the web works. No account or installation is needed, and the results are plain text and tables you can copy into a report or ticket.
