To make sure your PDFs are compliant, focus on:
Document properties: Fill in the title, author, subject, and any additional information.
Structure and style: Use a consistent heading hierarchy.
Meta information: Provide descriptive alt text for images, clear descriptions for forms, and labels for tables or lists.
Alternative versions: Where possible, provide alternative ways to access information, such as HTML.
For detailed instructions, please consult this series of training videos from AED CoP, or schedule a meeting to chat with an accessibility expert.
