Is Acrobat XI PDF Output Compliant with Section 508 and WCAG 2.1 AA?
Question details
The user wants to know if PDF files exported or edited using Adobe Acrobat XI automatically meet Section 508 and WCAG 2.1 AA accessibility standards.

- Product
- Adobe Acrobat XI
- Device & OS
- not provided
- Scenario
- Ensuring PDF documents are fully accessible and compliant with legal and web accessibility guidelines (Section 508 and WCAG 2.1 AA).
- Observed behavior
- Acrobat XI does not automatically generate compliant PDFs. It relies heavily on manual remediation and lacks the modern auto-tagging and accessibility tools found in newer software versions.
Before attempting to fix PDF accessibility, try to locate the original source document (such as the Word or presentation file). Correcting structural issues in the source document before exporting is significantly faster than manually remediating a PDF.
Upgrade to a Modern PDF Editor
Upgrading from Acrobat XI (released in 2012) to a current PDF editor is the most effective way to ensure accessibility compliance.
Acrobat XI is severely outdated and lacks modern auto-tagging features for complex elements like lists, tables, footnotes, and hyperlinks. The time and labor required to manually fix these issues in an older version usually outweigh the cost of an upgrade.
Modern PDF software includes updated accessibility checkers that automatically map elements to WCAG 2.1 AA standards.
Check your system to confirm you are running Acrobat XI or an older PDF tool.
Download and install a contemporary PDF editor that features a built-in accessibility checker and auto-tagging capabilities.
Open your document in the new software and run the Accessibility Check tool to automatically identify missing alt text, untagged reading orders, and structure issues.

Optimize the Source Document Before Exporting
The accessibility of a PDF heavily depends on how well the author structured the source document.
Manually Remediate PDFs in Acrobat XI
Use the built-in, albeit older, accessibility checker in Acrobat XI to manually identify and correct structural issues.
Create Accessible PDFs Seamlessly with WPS Office
Since PDF accessibility starts with a well-structured source document, WPS Office provides an excellent environment to create, format, and export highly compatible PDFs. By preparing your documents properly in WPS Writer, you can ensure your exported PDFs have the foundational structure needed for accessibility.
- 1. Structure your document in WPS Writer: Open WPS Writer and use the built-in Styles pane to apply proper Headings (H1, H2, H3) to organize your content logically.
- 2. Add Alternative Text to images: Right-click any images or charts in your document, select 'Picture Properties', and add a descriptive text in the Alternative Text field.
- 3. Export as PDF: Go to the 'Menu' at the top left, select 'Export to PDF', and ensure your structural formatting is preserved during the conversion.
- 4. Review in WPS PDF: Open the newly created PDF in WPS PDF to verify the document layout, hyperlinks, and overall readability.

Frequently Asked Questions
What is Section 508 and WCAG 2.1 AA compliance?
Section 508 is a US law requiring federal electronic content to be accessible to people with disabilities. WCAG 2.1 AA (Web Content Accessibility Guidelines) is the internationally recognized technical standard that outlines how to make digital content, including PDFs, accessible to screen readers and assistive technologies.
Why is Acrobat XI not recommended for PDF accessibility?
Acrobat XI was released in 2012. Since then, accessibility standards have evolved. It lacks modern auto-tagging features, improved accessibility checkers, and efficient tools for correctly tagging complex content like footnotes, tables, and dynamic hyperlinks.
Does converting a Word document to PDF automatically make it compliant?
No. The resulting PDF is only as accessible as the source document. If the original Word document lacks proper heading structures, image alt text, and formatted tables, the exported PDF will also fail accessibility compliance checks.
Can I automate PDF accessibility compliance completely?
While modern PDF editors can automate large portions of the process (like initial tagging and structure recognition), true compliance still requires some manual review. You must ensure that the logical reading order is correct and that alternative text accurately describes the images.
