Ever sent a PDF to a colleague or citizen only to hear, "I can’t open this—it’s not screen-reader friendly"? Or worse, faced a compliance audit because your agency’s digital forms locked out people with disabilities?

Public organizations don’t get a pass on accessibility. Laws like the Americans with Disabilities Act (ADA), Section 508 of the Rehabilitation Act, and WCAG 2.1 standards require all digital content—including PDFs—to be usable by everyone. Ignoring this isn’t just unethical; it’s illegal.

So where do you start? Let’s break down what accessibility really means for PDFs in government work, how to fix common issues, and which free tools can help you stay compliant without a huge budget.

What does ‘PDF accessibility’ actually mean?

Think of an accessible PDF like a well-designed building with ramps and elevators. A PDF should let anyone—regardless of disability—read, navigate, and interact with its content. This includes:

  • Screen readers that read text aloud must understand the document’s structure.
  • Keyboard-only navigation must work for people who can’t use a mouse.
  • Color contrast must be high enough for low-vision users.
  • Alternative text (alt text) must describe images, charts, and graphics.

Miss these? Your PDF becomes a digital barrier. And in government, that’s not acceptable.

Who enforces these rules?

ADA applies to all public entities. Section 508 specifically covers federal agencies and contractors. WCAG 2.1 (Web Content Accessibility Guidelines) is the global standard—even if not legally required, courts often use it to measure compliance.

Bottom line: If your PDF is part of a service, form, or communication, it must meet accessibility standards. No exceptions.

How to check if your PDFs are accessible right now

You don’t need fancy software to spot major issues. Here’s a quick checklist you can run in under 5 minutes:

  1. Open the PDF in Adobe Acrobat Reader (free). Go to View > Tools > Accessibility and run the Full Check tool.
  2. Try navigating with a keyboard. Press Tab to move through links and form fields. If you get stuck or skip content, your PDF isn’t keyboard-friendly.
  3. Use a screen reader (free tools available). For example, NVDA (NonVisual Desktop Access) is free and lets you test whether your PDF is readable.
  4. Check color contrast. Tools like WebAIM’s Contrast Checker can help. If text is hard to read on a gray background, it fails.

A Quick Check: Grab three PDFs from your agency’s website and test them. Can you fully navigate each one without a mouse? Can a screen reader read the text in order? If the answer is no, you’ve got work to do.

Fixing common PDF accessibility issues (without hiring a consultant)

Most accessibility problems in PDFs come from two sources: poor source files and improper tagging. Here’s how to fix them:

1. Start with the source document

Accessibility begins before you even create a PDF. If you’re exporting from Word, PowerPoint, or InDesign:

  • Use built-in heading styles. Don’t just make text big and bold—use “Heading 1,” “Heading 2,” etc. This helps screen readers understand structure.
  • Avoid scanned PDFs. If you’ve got a paper form you scanned, run it through PDF to Word first. Scans are images—screen readers can’t read them.

Try this now: Open a Word doc you’ve used to create a PDF. Press Ctrl + F and search for “Heading 1.” If you don’t see any, your document isn’t structured for accessibility.

2. Tag your PDF properly

Tags define the reading order and hierarchy of your PDF. Without tags, screen readers guess—and usually get it wrong. To check tags in Acrobat:

  • Go to View > Show/Hide > Navigation Panes > Tags.
  • Look for a logical structure. Headings should be labeled H1, H2, H3, and so on. Paragraphs should be P tags.

If your tags are a mess, you can re-tag manually or use Acrobat’s Automatic Tagging feature (it’s not perfect, but it’s better than nothing).

Pro tip: If your PDF has tables, use table tags and define headers. A screen reader should announce the table’s structure clearly.

3. Add alt text and fix language settings

Every image, chart, or graphic needs a clear alt text description. Don’t skip this—screen readers rely on it. In Acrobat:

  • Right-click an image > Edit Image > Alt Text.
  • Write a concise description. For example, instead of “Chart,” say “Bar chart showing 2024 budget allocations by department: Education 35%, Health 28%, Infrastructure 17%, Other 20%.”

Also, set the document language in Acrobat’s File > Properties > Advanced tab. Screen readers need to know if the text is English, Spanish, etc.

Free tools to make your PDFs compliant

You don’t need to spend thousands on consultants. These free tools can help you audit, fix, and maintain accessible PDFs:

  • Adobe Acrobat Reader (Free) – Use the built-in accessibility checker and tag editor.
  • PDFKro’s AI PDF Editor (/ai-edit) – Lets you add tags, alt text, and fix reading order without Adobe. Upload a PDF, and the AI suggests accessibility improvements based on WCAG 2.1.
  • PDFKro’s PDF Chatbot (/ai-rag) – If you’ve got a batch of old PDFs, upload them and ask the AI, “Which of these PDFs are missing alt text?” It’ll scan and flag non-compliant files instantly.
  • PDF to Word (/pdf-to-word) – Convert scanned or unreadable PDFs into editable text you can properly tag and format.
  • PDF Merge (/merge-pdf) – Combine multiple accessible PDFs into one clean document without breaking tags or alt text.

Why this matters: A single inaccessible PDF can trigger a complaint or lawsuit. Using these tools proactively saves you time, money, and headaches down the road.

Section 508 vs. WCAG 2.1: What’s the difference?

Section 508 is a U.S. federal law requiring federal agencies and contractors to make their electronic and information technology accessible. It’s mandatory for government work.

WCAG 2.1 is an international standard developed by the W3C. It’s not a law, but courts and agencies often use it as a benchmark. WCAG 2.1 has three levels: A (minimum), AA (recommended), and AAA (maximum). Most government bodies aim for WCAG 2.1 AA.

The overlap: Section 508 aligns closely with WCAG 2.1 AA. If your PDF meets WCAG 2.1 AA, it’s likely compliant with Section 508. But always double-check, especially for complex forms.

Real-world examples: What happens when PDFs aren’t accessible?

In 2023, a federal court ruled against a government agency because its online forms weren’t screen-reader compatible. The agency had to redesign 400+ forms and pay legal fees—all because a few PDFs weren’t tagged properly.

Another example: A county health department posted a vaccine signup PDF that wasn’t keyboard-navigable. A citizen with mobility issues sued under ADA. The county settled for $50,000 and had to retrain staff on accessibility.

Moral of the story: Accessibility isn’t optional. It’s a legal requirement with real consequences.

Your 30-day action plan to become compliant

You don’t have to fix everything overnight. Start small and build momentum:

  1. Week 1: Audit
    Run a Full Check on 10 high-traffic PDFs using Adobe Acrobat or PDFKro’s AI tools. Flag files with missing tags, alt text, or poor contrast.
  2. Week 2: Fix the easy wins
    Focus on low-hanging fruit: add alt text to images, correct heading tags, and set the document language. Use PDFKro’s AI PDF Editor to automate fixes where possible.
  3. Week 3: Train your team
    Schedule a 30-minute lunch-and-learn on PDF accessibility basics. Show them how to use built-in tools in Word and Acrobat. Share this guide and the free tools list above.
  4. Week 4: Monitor and improve
    Set up a monthly review. Use PDFKro’s PDF Chatbot to scan new uploads for compliance issues. Keep a log of fixes and share updates with leadership.

Try this now: Pick one PDF from your agency’s website. Run the Full Check in Acrobat. How many errors does it flag? That’s your starting point.

What about scanned PDFs and forms?

Scanned PDFs are the worst offenders. They’re essentially images—screen readers can’t read them. Here’s how to handle them:

  • Convert them first: Use PDF to Word to turn the scan into editable text. Then, retag and add alt text.
  • Use fillable forms: If your agency uses forms, make them fillable in PDF format. Use Acrobat’s form tools or PDFKro’s AI Editor to add proper labels and tab order.
  • Avoid images of text: If you must include a scanned document, add a text layer beneath it. This way, screen readers can still access the content.

Remember: A scanned PDF is not accessible. Period. There’s no workaround except to convert it.
