Imagine sending out a critical policy update as a PDF—but half your audience can’t read it. That’s the reality if your PDFs aren’t accessible. Public organizations have a legal and moral duty to ensure documents are usable by everyone, including people with disabilities. But accessibility isn’t just about ticking boxes—it’s about building trust and inclusivity. Let’s break down what PDF accessibility really means and how you can make your documents compliant.

Here’s the straight answer: PDF accessibility means creating documents that people with disabilities can navigate, read, and interact with using assistive technologies like screen readers or text-to-speech tools. For public organizations, this isn’t optional—it’s often required by law.

What Laws and Standards Apply to PDF Accessibility?

You’re probably familiar with Section 508 in the U.S., which mandates that federal agencies make their electronic and information technology accessible. But what does that mean for PDFs? Under Section 508, all PDFs must be accessible unless doing so would pose an undue burden.

Then there’s WCAG 2.1 (Web Content Accessibility Guidelines), the international standard for digital accessibility. WCAG breaks down accessibility into four core principles: perceivable, operable, understandable, and robust. For PDFs, this translates to:

  • Perceivable: Text alternatives for images, readable fonts, and sufficient color contrast.
  • Operable: Forms that can be filled out using a keyboard, not just a mouse.
  • Understandable: Clear headings, consistent navigation, and plain language.
  • Robust: Compatibility with assistive technologies.

Pro tip: If your PDF meets WCAG 2.1 AA standards, it’s almost certainly Section 508 compliant. Aim for AA—it’s the sweet spot between compliance and usability.

Why Bother with PDF Accessibility?

Because your audience deserves it. Over 26% of U.S. adults live with a disability, and many rely on assistive tech to access information. Non-compliant PDFs can lead to:

  • Legal trouble: Lawsuits under the ADA or Section 508 can be costly.
  • Lost trust: If your organization can’t provide accessible documents, stakeholders may question your commitment to inclusivity.
  • Inefficiency: Fixing accessibility issues after documents are published wastes time and resources.

How to Make Your PDFs Accessible: A Step-by-Step Guide

You don’t need to be a tech whiz to create accessible PDFs. Start with the source document—usually a Word file—and build accessibility in from the ground up. Here’s how:

1. Start with the Right Tools

Use Microsoft Word or Google Docs to create your document. These tools have built-in accessibility checkers that flag common issues like missing alt text or poor contrast. Pro tip: If you’re using Word, run the Accessibility Checker (Review > Check Accessibility) before converting to PDF. Fix any red flags first.

Once your document is ready, convert it to PDF using PDFKro’s Merge PDF tool. It preserves your formatting and gives you a clean slate for final adjustments.

2. Structure Your Content Properly

Headings are everything. Screen readers rely on heading tags (H1, H2, H3, etc.) to navigate documents. In Word, apply heading styles consistently. Avoid using bold or large fonts as headings—that won’t help a screen reader user.

Use built-in lists: Bulleted or numbered lists should be created using Word’s list tools, not by typing asterisks or numbers manually. This ensures screen readers announce them correctly.

3. Add Alt Text to Images and Graphics

Every image, chart, or icon needs a text description. In Word, right-click an image > Format Picture > Alt Text. Keep it concise but descriptive. If an image is purely decorative, mark it as such so screen readers ignore it.

Example: Instead of “Chart showing revenue,” try “Bar chart comparing quarterly revenue from 2022 to 2024, with 2024 showing a 15% increase.”

4. Ensure Color and Contrast Meet Standards

Color isn’t communication. Use tools like the WebAIM Contrast Checker to verify that text stands out against its background. Aim for a contrast ratio of at least 4.5:1 for normal text.

If you’re using color to convey information (e.g., red for errors), add a text cue too. Not everyone sees color the same way.

5. Create Accessible Forms and Tables

Forms in PDFs must be fillable using a keyboard. In Adobe Acrobat, use the Prepare Form tool to add proper form fields. Label each field clearly (e.g., “First Name” instead of “Field1”).

For tables: Use Word’s table tools to create tables, then convert to PDF. Avoid merged cells or complex layouts—they confuse screen readers. Keep it simple and linear.

6. Run the Accessibility Checker

Before publishing, run an accessibility audit. In Adobe Acrobat Pro, go to Tools > Accessibility > Accessibility Check. It’ll flag issues like missing alt text or improper heading structure. Don’t skip this step.

Common Mistakes to Avoid

PDFs aren’t just scans. If you’re converting a scanned document to PDF, run it through OCR (Optical Character Recognition) first. Scanned text isn’t machine-readable—screen readers can’t interpret it. Tools like PDFKro’s PDF to Word converter can OCR your scans and make them editable.

Don’t rely on PDFs alone. Always provide alternative formats, like HTML or plain text, for complex documents. Not all users can or want to use PDFs.

Watch out for:

  • Untagged PDFs: Without tags, screen readers treat your PDF like a blank page.
  • Language issues: If your document is in a language other than the default, set the language in Word before converting to PDF.
  • Password protection: Secure PDFs can block assistive technologies. Avoid password-protecting PDFs unless absolutely necessary.

A Quick Check:

  1. Does your PDF have a logical heading structure?
  2. Are images and charts labeled with alt text?
  3. Can a screen reader navigate the document from start to finish?
  4. Is the color contrast sufficient?
  5. Can forms be filled out using a keyboard?

If you answered “no” to any of these, it’s time to revisit your PDF.
