How to Make PDFs Accessible (WCAG-Friendly Checklist)

PDFs are still one of the most common ways organizations share reports, policies, applications, and statements. But many PDFs are difficult or impossible to use for people who rely on screen readers, keyboard navigation, text enlargement, or voice control. Making your PDFs accessible isn’t just good UX—it’s an important part of accessibility compliance and inclusive digital experiences aligned with WCAG.

This article walks through practical, repeatable steps to make PDFs accessible, plus what to check before you publish. If you’re newer to accessibility, it may help to first read What Is WCAG 2.2 and Why It Matters for context on how success criteria translate into real-world requirements.

What makes a PDF “accessible”?

An accessible PDF is structured so assistive technologies can understand and navigate it. That generally means:

• Readable text (not just an image of text)
• Correct tags for headings, paragraphs, lists, tables, and figures
• Logical reading order and meaningful structure
• Descriptive link text and document metadata
• Alt text for informative images
• Accessible forms with labels, instructions, and error cues
• Sufficient contrast and usable zoom/reflow where possible

These needs map to multiple WCAG criteria (for example: text alternatives, adaptable content, keyboard accessibility, focus order, and more). And because PDFs often contain “fixed layout” content, you must be extra intentional about structure and reading order.

Start with the source file (the easiest path)

The best way to create accessible PDFs is to build accessibility into the original document (Word, Google Docs, InDesign, etc.) and export to tagged PDF. Remediating an already-exported PDF is possible, but it typically takes longer and is easier to get wrong.

Before you export:

• Use built-in heading styles (Heading 1, Heading 2, etc.) instead of bold text to “fake” headings.
• Use real lists (bullets/numbering), not manual hyphens and line breaks.
• Add alt text to meaningful images (and mark purely decorative images as decorative where supported).
• Ensure tables have clear headers and a simple layout (avoid merged cells where possible).
• Write descriptive link text (avoid “click here”).
• Set the document language and include a clear title.

This is also where inclusive design habits pay off. If your team needs a foundation, the principles in Inclusive Design Principles for Beginners: A Practical Guide to Accessible Digital Experiences translate well to documents, not just web pages.

Export correctly: create a tagged PDF

When exporting, make sure you generate a tagged PDF. Tagging is the behind-the-scenes structure that allows screen readers to interpret headings, paragraphs, lists, and more.

Common export settings to look for

• “Document structure tags for accessibility” (Word and other tools often include this)
• Bookmarks from headings for longer documents
• Preserve hyperlinks
• Include metadata (title/author)

If your PDF is “flat” (no tags), assistive tech may read it as a confusing stream of content, or not at all.

Remediate in Adobe Acrobat: structure, order, and meaning

If you already have a PDF—or your export didn’t tag correctly—Acrobat’s accessibility tools can help. The goal is to ensure the PDF’s structure matches the visual layout and intended meaning.

1) Set document properties and language

• Set a descriptive title (Document Properties) and ensure it’s used for the window title.
• Set the primary language so screen readers use correct pronunciation rules.

2) Add/repair tags

Use the Tags panel to confirm you have a logical hierarchy:

• One H1 for the main title
• H2/H3 for sections and subsections (no skipping levels without reason)
• Paragraphs tagged as P, lists as L, list items as LI, and so on

Avoid using tags purely for visual style. Tags should communicate meaning and structure.

3) Fix reading order

Reading order is one of the biggest accessibility failures in PDFs, especially with multi-column layouts, sidebars, or complex visual arrangements. Use Acrobat’s Reading Order tool to ensure content is read in the correct sequence.

As a quick check, try selecting text from top to bottom—if the selection jumps around columns or pulls sidebar content in the wrong place, the reading order likely needs work.

Images, charts, and alt text: provide equivalents

Any image that conveys information needs a text alternative. Good alt text is specific and concise, describing the purpose of the image in context. Examples:

• Bad: “chart”
• Better: “Bar chart showing Q1 revenue rising from $1.2M to $1.8M across regions.”

For complex charts, consider adding a short alt text plus a longer description in nearby text, an appendix, or a linked data table. Decorative images should be marked as artifacts/decorative so they’re skipped by screen readers.

Tables: keep them simple and properly headed

Tables can be accessible, but only when they’re structured correctly. Best practices:

• Use header cells (TH) and define their scope (row/column) where possible.
• Avoid merged cells, nested tables, or layout tables.
• Provide a caption or introductory text that explains what the table represents.

If a table is mainly for layout, it’s usually better to redesign the content rather than force a complex table into a PDF.

Links and navigation: make it scannable

Accessible PDFs should support quick navigation, especially for longer documents:

• Create bookmarks from headings so users can jump between sections.
• Ensure link text is descriptive (e.g., “Download the 2026 benefits guide (PDF)” rather than “Click here”).
• Confirm link annotations are keyboard reachable and don’t rely on color alone.

If your organization is working across both web and PDF content, you may notice similar usability issues. Many teams start by fixing web patterns described in 7 Common Accessibility Mistakes on Websites (and How to Fix Them) and then apply the same “structure-first” approach to documents.

Accessible PDF forms: labels, tab order, errors

Forms are where PDF accessibility often breaks down. An accessible PDF form should:

• Have programmatic labels for every field (not just visual text рядом to it).
• Use a logical tab order that matches the visual flow.
• Include clear instructions and indicate required fields without relying only on color.
• Provide error identification and guidance when validation fails.

Test with only the keyboard: can you reach every field, operate controls, and submit without getting stuck? If the form is critical (for example, patient intake or appointment requests), accessibility becomes even more important—see Why online healthcare must be accessible for the real-world impact of inaccessible digital journeys.

Test your PDF: automated checks plus real assistive tech

Testing should combine quick automated checks with hands-on review:

Automated checks

• Run Acrobat’s Accessibility Checker to catch missing tags, missing alt text, and other common issues.
• Verify fonts, contrast, and whether the document is properly tagged.

Manual checks (high value)

• Keyboard-only: navigate links, form fields, and interactive elements.
• Screen reader spot check: headings navigation, reading order, link announcements, form labels.
• Zoom: increase zoom to 200–400% to confirm content remains usable without horizontal scrolling where feasible.

Because PDFs often live alongside web pages, monitoring accessibility across your site and document library matters. Platforms like Corpowid (corpowid.ai) can help teams identify and monitor accessibility issues at scale through automated audits, making it easier to prioritize fixes across templates and content types.

Publish with compliance in mind

Accessibility isn’t only a technical best practice; it’s increasingly tied to legal and policy obligations worldwide. Requirements differ by region and sector, but the trend is clear: organizations are expected to provide accessible digital content, including documents. For a broader compliance lens, read Digital accessibility in the grip of global regulations.

To reduce risk and improve usability, build a simple publishing workflow:

• Create an accessible document template (Word/InDesign) that already uses correct styles.
• Add a pre-publish checklist (tags, reading order, alt text, language, title, bookmarks).
• Keep a remediation path for legacy PDFs (prioritize high-traffic and essential services first).
• Maintain an accessibility statement and update it as you improve document coverage—Corpowid (corpowid.ai) also supports accessibility statement tooling to help communicate your approach clearly.

Accessible PDFs checklist (quick reference)

• Tagged PDF with correct heading structure
• Accurate reading order
• Document title + language set
• Alt text for informative images; decorative marked as artifacts
• Tables with headers and simple structure
• Descriptive links + bookmarks for long docs
• Forms with labels, tab order, instructions, and errors
• Test with keyboard and a screen reader; confirm contrast and zoom usability

When you treat PDFs as part of the same inclusive experience as your website, you make it easier for everyone to access critical information—employees, customers, students, patients, and the public.
