Link extractor bulk processing turns a single block of pasted HTML source into a deduplicated, ordered list of href targets, with explicit counts for unique, duplicate and skipped entries and without contacting any discovered destination. The job is source inventory: scan the markup you have, not the live page, and produce one normalized URL per line that you can paste into a spreadsheet, a crawler queue or a review document. A bulk run means the parser reads every link-bearing start tag in the document at once, normalizes absolute HTTP, HTTPS, mailto and tel targets directly, and resolves root-, path- and scheme-relative values against an optional credential-free base URL. JavaScript-driven links, executable schemes, empty values and invalid URLs are filtered out and tallied so the final length never hides a filtering decision. This is useful when an audit needs every anchor, area-map target, and stylesheet or canonical reference surfaced quickly from source you are authorized to inspect, rather than from a fragile browser-side crawler.

Bulk Link Extractor: Parse and Deduplicate Pasted HTML

Bulk link extraction in this context is a single-pass scan over a static HTML document rather than a streaming crawler that walks a live site. The extractor reads the source you supply, applies a bounded set of normalization rules, and returns a finished list you can copy. There is no rate-limiting to worry about, no proxy configuration, and no risk of accidentally hitting an internal address during the scan because the tool never requests the URLs it finds. The trade-off is honesty about scope: if a link was injected by JavaScript after page load, it is not in the source and therefore not in the result. The same goes for content rendered by a framework application after hydration. Bulk extraction is the right tool for source-level audits, snapshot comparisons, and bulk-cleanup tasks where you already hold the HTML, not for capturing links that only exist once a page has executed its scripts.

Three HTML Tags the Extractor Scans

A page can carry link targets in three different HTML elements, and the parser handles all of them together because the document is treated as a source-level inventory rather than a navigation map. Before link scanning begins, the implementation removes comments and common raw-text containers such as script, style, textarea, title, iframe, noembed and noframes, which prevents strings that merely look like anchor markup inside JavaScript or literal text from becoming false links.

ElementWhere it appearsTypical href
aBody anchors, navigation, call-to-action buttons<a href="/pricing">Plans</a>
areaImage-map hotspots inside a map element<area shape="rect" href="/help">
linkHead-level stylesheets, icons, canonical, alternate<link rel="canonical" href="https://...">

The parser reads the href attribute on each element, decodes a bounded set of character references (decimal and hexadecimal numeric references plus the small named set amp, quot, apos, lt and gt), normalizes the target, deduplicates, and emits the list.

  1. Paste the authorized HTML source into the input area on the Link Extractor page, keeping the document under the 200,000-character input cap. If your HTML contains relative href values such as /pricing, ../guide or //cdn.example.com/file.js, add the absolute page URL where the source was rendered into the optional base-URL field so those paths can be resolved against it. The base must use HTTP or HTTPS and cannot include credentials.
  2. Run the extract and review the three counts the interface exposes: unique targets returned, duplicates collapsed, and skipped entries. Duplicates are removed after normalization, so two identical relative links that resolve to the same absolute address collapse to a single line. First-seen order is preserved, which keeps the list usable for source-order comparisons.
  3. Copy the one-per-line result into a spreadsheet, a crawler queue or a review document. Treat the list as an inventory and separately verify HTTP status, redirects, rel meaning and dynamic DOM links with an authorized crawler when those facts matter.

Why a Base URL Matters for Bulk Extraction

Relative paths are common in production HTML because authors write /pricing or ../guide without thinking about absolute hosts. A bulk extractor must therefore resolve those values rather than literally emit them, otherwise the resulting list would be useless for any cross-host audit. When a valid HTTP or HTTPS base URL is supplied, root-relative values such as /pricing under https://example.com/products/page become https://example.com/pricing; path-relative values such as ./guide resolve against the base path; parent-relative values such as ../docs climb the path tree; and scheme-relative values such as //cdn.example.com/file.js inherit the base scheme. Without a base, relative values are emitted as-is so the output does not silently invent a host. Absolute HTTP, HTTPS, mailto and tel values are normalized directly regardless of whether a base is present.

Skipped Targets and Why the Count Exists

Not every href value in HTML is a navigation target the tool should return. The skipped count exists precisely to make those omissions transparent instead of burying them inside a short list. Mail and telephone targets are retained because they are legitimate link destinations even though they are not web pages.

CategoryTreatmentReason
Empty href valuesSkippedCannot point to a resource
Same-document fragments such as #only and #sectionSkippedPoint inside the same page, not external
javascript: targetsSkippedExecutable scheme, security risk
data: targetsSkippedEmbedded payload, not a resource address
vbscript: targetsSkippedExecutable scheme
Invalid absolute URLsSkippedFailed URL validation
mailto: targetsRetainedLegitimate link destination
tel: targetsRetainedLegitimate link destination
Relative values without a baseRetained as relativeOutput never invents context

If a value is dropped, the skipped count increases by one. This means a list of 50 unique targets with a skipped count of 7 reflects an honest filtering pass, while a list of 50 with a skipped count of 0 means every found value was either retained or considered safe.

Reading the Unique, Duplicate and Skipped Counts

The three counts reported by the interface are not interchangeable. The unique count is the length of the list you can copy. The duplicate count records how many times a normalized target appeared more than once in the source, which is useful for spotting redundant navigation patterns, repeated canonical references, or pagination links that point to the same target. The skipped count records values that were filtered for safety or validity reasons. Together they let you verify the source coverage of the scan: if unique is 50, duplicate is 12 and skipped is 3, the parser found 65 href-bearing tags in the document. A high duplicate count next to a moderate unique count usually means the HTML is well-organized; a high skipped count next to a low unique count often means the document contains many malformed or programmatic hrefs.

Limits That Change a Bulk Result

The bulk scan is bounded in several ways that you should plan around. The input is capped at 200,000 characters, which keeps the interactive scan responsive but means very large documents must be split or processed with a controlled crawler. Severely malformed markup, unusual unquoted attributes, missing raw-text closing tags and browser error recovery can produce a different parse tree than a full browser DOM, so for legal, security or migration audits the source extraction should be compared with a browser DOM export and a real crawler rather than trusted alone. The parser only scans static source, which means links inserted by JavaScript after page execution are not present and will not appear in the list. The tool does not execute scripts or render a framework application, so dynamic DOM links require a separate capture step.

A clean list of targets is an inventory, not a health report. The extractor does not label internal versus external links, test HTTP status, follow redirects, evaluate rel attributes such as nofollow, sponsored or ugc, or decide SEO quality. A listed target may redirect, return an error, require authentication, be blocked by robots controls or intentionally point at a third-party domain. For crawl-budget reviews, link-equity studies and migration audits, the bulk extraction step is the inventory layer that feeds a downstream tool such as an HTTP crawler, a status checker or a rel-attribute parser. Treat the Link Extractor output as the starting point for those reviews, not as the conclusion.
