An Accessibility Checker is a powerful tool that scans digital content—such as websites, documents, and applications—for compliance with accessibility standards like WCAG 2.1. It automatically detects issues that may prevent users with disabilities from fully accessing content, such as missing alt text, poor color contrast, or incorrect heading structures. Ideal for content creators, developers, and compliance teams, an accessibility checker helps identify barriers early in the process, streamlining remediation and ensuring a more inclusive user experience. Many checkers also provide clear, actionable guidance to support ongoing accessibility improvements.
