Digital accessibility tools
Browser-based scanning tools
There are multiple accessibility scanning tools that are free and available online. Provided below is a recommended list that can help identify accessibility errors on a webpage. While automated tools can be very helpful, they will only discover around 40 percent of accessibility errors, so always manually test pages where possible.
Note: If you manage a Wayne.edu site, you have access to the full SiteImprove report system. Email accessibility@wayne.edu for more info or access.
Canva Accessibility Checkers
There are two different accessibility scanners available through Canva: UDOIT and the Canvas accessibility checker. Both are recommended to help ensure online content is accessible. For additional information, view the OTL Virtual Resource Hub.
Color contrast
The Colour Contrast Analyser (CCA) helps you determine the legibility of text and the contrast of visual elements, such as graphical controls and visual indicators to meet AA Web Content Accessibility Guidelines (WCAG). This tool features:
- WCAG 2.2 compliance indicators
- Several ways to set colors: raw text entry (accepts any valid CSS colour format), RGB sliders, colour picker (Windows and macOS only)
- Support for alpha transparency on foreground colors
- Color blindness simulator
The Colorblind Web Page Filter resource allows you to view your website pages using colorblind filters. This is helpful when creating content with images to ensure an equitable viewing opportunity for all users.

Apple VoiceOver
VoiceOver is available on all Mac devices including phones. When testing a website, VoiceOver will work best with Safari.
