Siteimprove Accessibility Checker - Chrome Extension

Guðrún Gústafsdóttir avatar

The Siteimprove Accessibility Checker is a free tool available as a Google Chrome Extension to check any webpage for accessibility issues at any given time. The Siteimprove Accessibility Checker uses the same checking engine as the Siteimprove Accessibility platform product. It provides:

  • An immediate overview of your page's accessibility issues
  • Exactly where the issue appears on the page and in the code (Inspect view)
  • Clear explanation of how they affect your users
  • Specific recommendation on how to fix issues, including links to the relevant WCAG techniques

All analysis is done entirely within the Chrome browser, allowing secure evaluation of password-protected or non-public pages, multi-step forms, and dynamic content.

Note: The Siteimprove Accessibility Chrome extension can be used on HTML web page content. It is not possible to check PDF content with this extension.

I'm already a Siteimprove Accessibility customer, how can I benefit from using the Siteimprove Accessibility Checker?

  • Check pages directly in your browser without giving anyone access to the content of the tested page (e.g. during development)
  • Check pages that require a login (e.g. intranets or other firewall-protected pages) on the fly, anytime
  • Check page stages and content that is only activated on user input (e.g. multi-step forms)

How do I install the Siteimprove Accessibility Checker?

  1. Open the Chrome browser (or download the Chrome browser if you do not have it).

  2. Install the Siteimprove Accessibility Checker Chrome extension from the Chrome Webshop or search for Siteimprove Accessibility Checker.
