About W3C Link Checker
A free tool by the W3C to check for broken links, anchors, and referenced objects in web pages, CSS style sheets, or recursively across an entire website. It helps ensure the quality and validity of web documents.
The W3C Link Checker is a free, authoritative tool provided by the World Wide Web Consortium (W3C) for web developers and site administrators. Its primary function is to identify broken links, anchors, and other referenced objects within web documents. Users can initiate a scan by entering a URL, uploading a file, or pasting markup directly. The tool can perform a recursive check, allowing it to crawl an entire website to a user-defined depth. It is a purely functional, web-based utility with no pricing, tiers, or commercial support options. It is designed to help maintain website quality and is recommended to be used alongside other W3C validation tools like the Markup Validator. The software is open-source and can be installed locally for users who need to perform extensive checks without the limitations of the public online version.
