Open the PDF you want to adjust in Adobe Acrobat Pro.
Select Tools from the toolbar.
Choose Accessibility from the list of tools.
In the left pane, select Reading Order.
In the dialog box that opens, review the highlighted content areas and their assigned reading order numbers.
To change the reading order, select a content area and adjust its order number as needed.
If necessary, use the options to split, merge, or reassign content areas to ensure logical reading sequence.
After making changes, review the order visually to confirm it matches the intended logical flow.
Save the PDF to preserve your changes.
You can use the Fix reading order tool to visually adjust and verify the sequence in which assistive technologies will read your PDF content.
This runs in the Acrobat app - there is no separate API for this task.
PDF/UA is a specific standard just for PDF documents. WCAG (Web Content Accessibility Guidelines) is a set of rules for making all kinds of web content accessible, not just PDFs. Often, regulated work needs to follow both standards to be fully compliant, as they cover different aspects of accessibility.
It is much better to fix accessibility problems in the original document (like a Word file) before you make it a PDF. When you fix the source, the PDF you create from it will often be accessible from the start. This saves a lot of time and effort compared to fixing a PDF after it has already been made, which can be a very long process.
Yes, the PDF Accessibility Auto-Tag API is designed to work with both native PDFs (created digitally) and scanned PDFs. It uses smart technology to identify headings, tables, lists, and paragraphs, and it also recognizes the language, making scanned documents more accessible.
Alt text, or alternative text, is a short description of an image or graphic in your PDF. It matters because screen readers use this text to tell visually impaired users what the image is about. Without alt text, these users would not understand the visual content, making the PDF less accessible.
