About

Modern web environments are saturated with bloated URLs containing intrusive tracking parameters and nested redirects. This URL Extractor utilizes high-precision regular expressions to isolate http and https protocols from disorganized strings, raw HTML, or mixed-content logs. Unlike basic scrapers, it handles edge cases where URLs are adjacent to punctuation, quotes, or bracketed delimiters. The tool is designed for developers auditing source code and marketers performing competitive analysis who require clean, unique, and actionable datasets.

Accuracy is paramount when dealing with Percent-Encoding and special characters. This tool validates each string through the URL API to ensure structural integrity while offering deep-cleaning logic to remove UTM, fbclid, and other telemetry tags. By processing data entirely in the browser, sensitive URLs never reach a server, maintaining strict data privacy for internal links and development environments.

Formulas

The extraction process relies on a non-greedy, boundary-aware Regular Expression designed to exclude trailing punctuation often found in natural language text.

{

Pattern = /https?://[^\s"'<>^`{}|\\\]\[]+/giValidation → new URL(match)

To compute the unique set of sanitized links L from input T, the algorithm applies a mapping function f that removes search parameters defined in the tracking blacklist.

n∑i=0

L = Set(map(T⋅match(Pattern), link → link⋅stripParams()))

Frequently Asked Questions

The extractor uses a custom boundary regex that excludes characters like periods, commas, and closing brackets if they appear at the very end of a URL string. This ensures that links pulled from sentences (e.g., 'Check out https://site.com.') don't include the trailing period in the final URL.

No. This tool is specifically designed for Absolute URLs (starting with http or https). Relative paths are highly context-dependent and require a Base URL to be useful, which is outside the scope of a general-purpose text extractor.

The Deep Cleaning algorithm targets over 15 common telemetry tags including utm_source, utm_medium, utm_campaign, utm_term, utm_content, fbclid (Facebook), gclid (Google), msclkid (Bing), mc_eid (Mailchimp), and various session identifiers like _hsenc or _ref.

Yes. You can paste the raw source or upload the .html file directly. The tool efficiently handles large blocks of code, ignoring tags, attributes, and script logic to focus solely on the protocol strings.
