Every time you export a Word document to PDF, you need to remember to check a box in the Options dialog to create tagged, accessible output. Most people forget. The default settings produce PDFs that look fine but lack the structural tags that screen readers, search engines, and AI tools use to understand the document's organization. Changing the default so that every export is automatically accessible eliminates the need to remember.
Tagged, accessible PDFs are not just for compliance. They are document structure that benefits everyone: screen reader users navigate by headings, search engines index content more accurately, AI tools extract structured information more reliably, and you can generate a table of contents from the PDF's tag tree. Setting Word to PDF accessibility as the default is a one-time configuration change that improves every document you produce.
What Tagged PDF Means and Why It Matters
A tagged PDF contains a hidden structural layer, similar to HTML, that labels each element on the page according to its role. A heading is labeled as H1, H2, or H3. A paragraph is labeled as P. A list is labeled as L with each item as LI. A table is labeled as Table with rows as TR and cells as TD or TH for header cells. An image is labeled as Figure with optional Alt text. This tag structure tells assistive technology how to read the document. The screen reader announces headings as headings and lets the user jump between them. It reads tables cell by cell with column headers. It skips decorative elements marked as artifacts.
An untagged PDF has none of this structure. It is a flat collection of characters at positions on pages. A screen reader reads everything in document order, which may not be the logical reading order. Headings are not announced as headings. Tables are read as continuous text with no column context. The experience is confusing and disorienting for assistive technology users. The Allyant PDF Accessibility Index found that 94.75% of public-facing PDFs fail basic accessibility standards (Allyant, 2026). Most of those failures trace back to the export settings in the authoring application.
How to Change the Default PDF Export Settings in Word
Word's PDF export settings are sticky within a session but reset when Word is closed. To make them permanent, you need to change the defaults through Word's Options. Go to File, Options, Save. Under "Preserve fidelity when sharing this document," check "Save form data as delimited text file" to preserve data structure. Also set "Embed fonts in the file" to ensure consistent rendering across devices.
The accessibility settings themselves are in the Save As PDF dialog. Go to File, Save As, choose PDF. Before clicking Save, click Options. Check "Create bookmarks using Headings" and "Document structure tags for accessibility." These two checkboxes are the key settings. The problem is that Word does not remember these settings between sessions. You must check them each time, or you must use a workaround.
The Workaround: Create a Macro or Use a Different Export Method
If you find yourself repeatedly checking the same boxes in the PDF export dialog, create a simple Word macro that exports to PDF with your preferred settings. Open the Visual Basic Editor with Alt+F11. Insert a new module and paste a script that sets the PDF export options to include bookmarks and tags, then calls the export function. Assign the macro to a keyboard shortcut like Ctrl+Shift+P for quick access. The macro approach remembers your settings permanently because they are encoded in the script.
A simpler workaround for users who do not want to create macros: use WukongPDF's Word-to-PDF conversion. Upload the Word document and the conversion automatically generates tagged, accessible PDFs with bookmarks and document structure. The browser-based approach applies accessibility settings by default, requiring no configuration. This is faster than training yourself to check the boxes in Word and more reliable because the settings cannot be accidentally skipped.
Verifying That the Default Is Working
After setting your preferred method, verify that the exported PDF actually contains tags. Open the PDF in Adobe Acrobat. Go to File, Properties, and look for "Tagged PDF: Yes" in the Description. Open the Tags panel on the left side to see the tag tree. The tags should reflect your document's structure. If the Tags panel is empty or shows only a single container with no structure, the tagging settings were not applied.
Run an accessibility check as a final verification. Acrobat's Accessibility Checker and WukongPDF's PDF Accessibility scanner both evaluate the tagged structure and flag issues. The report should show no untagged content, a logical reading order, and alt text on images. If issues appear, they are typically in the source Word document, missing heading styles on headings that were manually formatted, images without alt text, tables without header rows, rather than in the export settings. Fix the source document and re-export.
The habit of exporting accessible PDF Export compounds over time. Every tagged PDF you create is accessible to assistive technology, indexable by search engines, and extractable by AI tools. The 30 seconds spent enabling the settings on one document is trivial. Multiplied across every document produced over a career, the cumulative benefit to readers who rely on document structure is enormous.
For organizations that need to demonstrate accessibility compliance, such as government agencies subject to Section 508 or businesses subject to the ADA, configuring Word's default export for tagged PDFs is part of a broader accessibility strategy. But it is a foundational part because it affects every document. No amount of post-export remediation can fully compensate for PDFs that were exported without tags from the start. The default setting is the single most impactful accessibility improvement most organizations can make.
A quick way to check whether an organization's PDFs are consistently tagged: download 10 random PDFs from the organization's website. Open each in Acrobat and check the Tags panel. If 8 or more are tagged, the organization has good accessibility practices. If fewer than half are tagged, the default export settings are not configured. This 10-file spot check takes 15 minutes and provides a reliable indicator of whether accessibility is built into the document workflow or bolted on afterward.
One often-overlooked benefit of consistently tagged PDFs: they are significantly easier to repurpose. A tagged PDF can be exported to Word, HTML, or plain text with its structure intact because the tags tell the conversion engine which text is a heading, which is body, and which is a list. An untagged PDF exported to Word produces a flat wall of text with no structure. The tagging you enable at export time pays dividends every time the document is converted to another format in the future.
