In addition to all of the other principles listed here, PDF documents and other non-HTML content must be accessible. If you cannot make it accessible, consider using HTML or providing another accessible alternative.
Even if the original purpose of a PDF or Word document was for print only, as soon as it is put on a website or emailed, it becomes a digital document and the accessibility standards apply.
Before deciding to post a PDF to the web, the first questions to ask is “Can this be an HTML web page instead?” Avoid posting PDF and Word documents when possible.
Guidelines for Documents
The same guidelines that apply to a web page are true for PDFs and Word docs. Before publishing documents, consider the following:
- Avoid using PDF and Word documents on the web if possible. Use an HTML page instead.
- Start with an accessible document. If you are starting with a Word document and converting it to a PDF document, ensure that the Word document is accessible first.
- Ensure that images have informative alt text.
- Correctly uses headings, lists, and tables.
- Provide meaningful link text.
- Check color contrast.
- Ensure keyboard-only users can tab through the document in a logical order.
