Extract links from HTML source

To list the links on a page, paste its HTML source, extract every absolute URL, then remove stylesheets, scripts and images. This recipe filters out URLs ending in .css, .js, .png, .jpg, .svg, .webp or .ico, removes duplicates and sorts the rest, leaving the page links you would audit for SEO or broken-link checks.

Extract links from HTML: questions and answers

Can I list only external links?

Yes. Add Filter lines set to Remove with your own domain, for example example.com, after the extract step.

Does it fetch the page for me?

No. Flow never makes network requests. Copy the source with your browser's View Source and paste it.

Are mailto: and tel: links included?

No, the URL extractor only matches http and https. Use the email extract type for mailto addresses.
