What is WCAG Accessibility?

The Web Content Accessibility Guidelines (WCAG) are the global standard for making websites accessible to people with disabilities. Developed by the World Wide Web Consortium (W3C), WCAG is the technical foundation for most accessibility laws worldwide — including the ADA, Section 508, EAA, and AODA.

WCAG 2.1 (the current version) has three compliance levels:

  • Level A: The most basic web accessibility features (minimum requirement)
  • Level AA: The standard most laws require (ADA, Section 508)
  • Level AAA: The highest level of accessibility (not required by law)

Why You Need a WCAG Checker Tool

Manually checking every WCAG criterion is nearly impossible for a single website. There are over 50 success criteria across three levels. A wcag checker tool automates this process, saving you hours of work.

Using a website accessibility checker free tool helps you:

  • Find violations instantly without technical skills
  • Prioritize fixes based on severity (A → AA → AAA)
  • Track your compliance progress over time
  • Avoid expensive ADA lawsuits
