Why Extract and Deduplicate URLs?
Raw text - whether it's HTML source, an email newsletter, a markdown document, or a scraped article - rarely comes with its links neatly separated. They're embedded in paragraphs, hidden in anchor tags, repeated across multiple mentions, and mixed with everything else. This template cuts through that noise and gives you a clean, unique list of every URL found.
The Three Steps
1. Extract URLs
Scans the entire input for absolute URLs starting with http:// or https://. Matches URLs embedded in prose, inside HTML attribute values, or listed on their own lines. Each found URL is placed on its own line in the output. Query strings, fragments (#anchor), and subpaths are all preserved.
2. Remove Duplicate Lines
The same URL often appears multiple times in text - a call-to-action repeated three times in an email, or a navigation link that appears in both header and footer of an HTML page. This step keeps only the first occurrence of each URL.
3. Remove Empty Lines
Strips any blank lines from the output so the final list is a dense, import-ready set of unique URLs - one per line.
Common Use Cases
Outbound Link Audits
Paste the HTML of a page to extract all outbound links. Review them for broken links, outdated references, or opportunities to update anchor text - without manually hunting through the source.
Building Backlink Prospect Lists
If you've exported a list of competitor pages or industry roundups, extract the links they cite to identify high-authority sources you could reach out to or seek coverage from.
Newsletter and Email Link Auditing
Before sending an email campaign, paste the HTML into this tool to verify every link is present and none are duplicated. After sending, paste the received email source to check all links resolved correctly.
Scraped Content Processing
When processing large amounts of scraped web content, extracting and deduplicating URLs is often the first step before any further analysis - identifying unique domains, checking for affiliate links, or building a sitemap of a site.
Research and Citation Tracking
Pull URLs from a research document, report, or article to build a list of all cited sources. Useful for fact-checking, academic referencing, or archiving content.
Frequently Asked Questions
Does it extract URLs from HTML anchor tags?
Yes. The extractor finds URLs in raw text, inside href="..." attributes, and in any other position. It matches the URL pattern itself, not the HTML structure.
What about URLs with query strings like ?utm_source=email?
The extractor preserves the full URL including query strings and fragments. If the same base URL appears with different query strings, they'll be treated as different URLs by the deduplication step - which is usually correct behavior for link auditing.
Will it work on very long pages?
Yes. Processing is entirely in-browser and handles large HTML documents without issues. Paste the full page source and get all URLs in seconds.
Can I filter the results to only keep URLs from a specific domain?
Open in Tool Combiner and add an Extract Lines Containing step after the URL extraction - set it to your domain and only matching URLs will pass through.
