TheWCAG Accessibility Evaluation Tool

WAVE Evaluation Tool

Evaluate web accessibility within your browser. WAVE is a web accessibility evaluation tool developed by WebAIM.org. It provides visual feedback about the accessibility of your web content by injecting icons and indicators into your page. No automated tool can tell you if your page is accessible, but WAVE facilitates human evaluation and educates about accessibility issues. All analysis is done entirely within the Chrome browser allowing secure valuation of intranet, local, password protected, and other sensitive web pages. To run a WAVE report, simply click on the WAVE icon to the right of your browser address bar, or select "WAVE this page" from the context menu. WAVE errors align with WCAG 2.2 failures. The WAVE interface facilitates human evaluation of many other aspects of accessibility and Web Content Accessibility Guidelines, ADA, and Section 508 compliance.

Version 3.3.0.0 (October 2025) adds numerous new features, enhancements, and bug fixes. Resetting the extension no longer refreshes the page, thus supporting better testing of dynamic content. The Summary and Details panel are now combined. The AIM Score is presented. Viewing the Order, Structure, or Contrast tabs now filters to only relevant page icons. The WAVE sidebar can now be collapsed out of view. Version 3.2.7.2 (September 2024) fixes a bug that disallowed checking of local files and suppresses errors in some cases where role="presentation" is present. Version 3.2.7.0 (August 2024) adds compatibility with Manifest v3. Inputs with aria-disabled=true are no longer considered for contrast checking. Version 3.2.6.0 (August 2024) adds support for contrast checking when foreground alpha/opacity is defined. The Contrast sidebar tools are updated to support foreground alpha.
