Every WCAG 2.1 Level A and AA success criterion, grouped by Perceivable, Operable, Understandable and Robust — check items off as you audit your site and your progress saves automatically.
Every real WCAG 2.1 Level A and Level AA success criterion, not a shortened summary.
Checkboxes persist in your browser, so you can pick a long audit back up later.
Sections match the official Perceivable, Operable, Understandable and Robust structure.
Use this checklist as a working audit companion while you review a real page or product.
WCAG organizes every success criterion under four principles, abbreviated POUR. Together they cover the full experience of using a website, from whether content can be perceived at all to whether it keeps working with assistive technology and future browsers.
Information and interface components must be presentable to users in ways they can perceive, such as text alternatives for images and sufficient color contrast.
Interface components and navigation must be operable, including full keyboard access, enough time to read content and no navigation that traps or disorients.
Information and the operation of the interface must be understandable, covering readable text, predictable behavior and helpful input error handling.
Content must be robust enough to be interpreted reliably by a wide range of user agents, including current and future assistive technologies.
Questions about WCAG levels, saved progress and what this checklist does and doesn't guarantee.
The Web Content Accessibility Guidelines (WCAG) 2.1 are the standard published by the W3C for making web content usable by people with disabilities. Success criteria are organized under four principles: Perceivable, Operable, Understandable and Robust, known together as POUR.
Level A covers the most basic accessibility requirements a site must meet. Level AA adds a further set of criteria and is the level most laws and organizational policies reference as the practical compliance target. This checklist includes all 30 Level A and 20 Level AA criteria.
Yes. Every checkbox you tick is saved to your browser's local storage automatically, so your progress is still there next time you open this page on the same device and browser.
Level AAA is the strictest tier and W3C itself does not recommend requiring it as a general policy for entire sites, since some AAA criteria cannot be satisfied for all content types. This checklist focuses on the A and AA criteria that most real-world standards require.
No. This checklist is an educational self-assessment aid, not a certified audit. Meeting WCAG criteria in good faith is strong evidence of accessible design, but formal legal compliance (such as under the ADA or EN 301 549) should be verified with an accessibility professional or auditing tool.
