Canvas has two accessibility tools. The Accessibility Checker helps you find and fix accessibility issues. Blackboard Ally on Canvas not only helps you find and fix inaccessible content, but it also converts your uploaded files into alternative formats to increase the accessibility of the content.
The Canvas Accessibility Checker is the primary tool for checking the accessibility of your course and course content. You can get to the Accessibility Checker by selecting its icon in the bottom right of the Canvas Rich Content Editor.
If there are accessibility issues on the page, this will be indicated by a number. 
Select the icon and a window will pop up on the right-hand side of the screen with information about the accessibility errors detected.
The Accessibility Checker automatically checks the accessibility of tables, images, document files, lists, headings and color contrast.

Clicking on the gauge will open a window on the right-hand side of the screen with information about how to fix the document or image.
Alternative FormatsIn addition to accessibility scores and help, Ally automatically generates alternative accessible file formats for all files you upload to Canvas. Students can download these alternative formats, allowing them greater freedom about how they consume the content in your course. The file types created include PDF, ePub, audio, HTML, braille, and machine-translated versions.
