Why Use a WCAG Contrast Checker for EAA Compliance?

As the European Accessibility Act (EAA) and global standards like WCAG 2.1 become mandatory in 2025 and 2026, digital accessibility is a legal requirement. Our WCAG contrast checker helps you instantly verify that your text is readable for users with visual impairments. Because we process every calculation locally in your browser, your design data remains 100% private — essential for corporate audits and proprietary projects.

Key Standards for Accessible Web Design

  • WCAG 2.1 / 2.2 AAA: The highest level of accessibility, requiring a 7:1 ratio for maximum inclusivity.
  • EAA 2025/2026: Legal compliance frameworks that prioritize color contrast as a core accessibility pillar.
