WCAG Checker

Test web content against Web Content Accessibility Guidelines (WCAG 2.1) standards

Overview

The WCAG Checker helps you evaluate web content against the Web Content Accessibility Guidelines (WCAG) 2.1 standards. Test text, images, forms, links, and headings to ensure your content is accessible to all users, including those with disabilities.

Tips

  1. Start with Level AA: Most organizations target AA compliance as it balances accessibility with implementation effort. Only move to AAA if required.

  2. Test Different Element Types: Check text for contrast, images for alt text, forms for labels, and headings for proper hierarchy. Each element type has specific requirements.

  3. Fix Critical Issues First: Address high-priority problems like missing alt text and poor contrast before tackling minor issues. The tool highlights severity levels.

  4. Test Iteratively: Re-check your content after making fixes to ensure changes resolve the issues without creating new problems.

  5. Combine with Manual Testing: Automated tools catch about 30% of accessibility issues. Use this tool alongside keyboard navigation and screen reader testing for comprehensive coverage.
