Tips for Making Online Documents Accessible: Word, PowerPoint, Excel & PDF
Web accessibility means committing to making your website accessible to all users, regardless of their physical or sensory ability. But inclusive design extends beyond your website. To be truly accessible, any documents provided as links to download must also be accessible.
This is often overlooked on university websites and online courses, which must comply with certain legal accessibility standards for education. It’s very important to make sure that all of the documents that people can download from your site are indeed accessible.
In our webinar “10 Tips for Creating Accessible Web Content with WCAG 2.0,” presenter Janet Sylvia of the University of Georgia’s Web Accessibility Group shared a wealth of resources and tools to make sure your online documents comply with WCAG. Below are some of her recommendations.

Universal Tips for Creating Accessible Documents
These accessibility tips apply to just about any document (PDF, HTML, Word, Excel, PowerPoint, etc). They are best practices for making documents accessible to people who use screen-readers or keyboard navigation. Make sure you’ve taken these steps before posting your documents online.
Page Titles, Headings, & Semantic Structure
<title>should match Heading 1
- Properly nest headings. There should be 1 H1 tag. Use H2 tags for headers, H3 for sub-headers, H4 for sub-sub headers, etc. Never choose a header tag just for the styling; it has to make sense semantically.
<ol>for Ordered lists and
<ul>for Unordered Lists, instead of using dashes or numbers
<strong>instead of bold and
<em>instead of italics
- Make sure anchor text makes sense when read out of context
- Anchor text should describe the link destination
- Use unique anchor text for each unique hyperlink
- Avoid hyperlinking only vague calls to action like “click here, “email me,” or “download now”
Add Alt Text for All Non-Text Content
- Every image requires Alt text. Alt text should concisely describe the image to a user who does not see it.
- Include a long Description when Alt alone is not enough; for example, a map showing directions from point A to point B, describe the path taken.
