Interactive WCAG 2.1 compliance tracker. Check off criteria as you audit, filter by level, and export a report. Progress is saved in your browser.
WCAG (Web Content Accessibility Guidelines) is the international standard for web accessibility, published by the W3C. Version 2.1 has three conformance levels: A (minimum), AA (recommended for most sites), and AAA (highest). Most laws and policies reference WCAG 2.1 Level AA.
Level A covers the most basic accessibility requirements like text alternatives for images and keyboard access. Level AA adds contrast ratios, resize support, and consistent navigation — this is the standard most organizations target. Level AAA includes enhanced contrast, sign language, and simpler reading levels — it's aspirational for most sites.
For a given conformance level, yes — WCAG requires that all criteria at that level (and below) are met. However, criteria only apply to relevant content. If your site has no video, video-related criteria don't apply. This checklist lets you mark items as not applicable.
