What is PDF Accessibility?

PDF accessibility ensures that PDF documents are usable by people with disabilities who rely on screen readers, screen magnifiers, and other assistive technologies. An accessible PDF includes proper tags, reading order, alt text for images, and form fields that can be navigated via keyboard. The PDF/UA (Universal Accessibility) standard (ISO 14289) defines technical requirements, and WCAG 2.1 applies to PDFs when they are used as web content.

Why PDF Accessibility Matters for Legal Compliance

ADA Title III, Section 508, and EAA explicitly cover PDF documents. Lawsuits citing inaccessible PDFs (e.g., bank statements, medical forms, product manuals) have increased significantly. Common failures include missing tags, incorrect reading order, and images without alt text — all of which can trigger legal action and fines.

Complete Guide to PDF Accessibility — WCAG 2.1 & PDF/UA

Now that you understand how our PDF accessibility checker works, let's dive deeper into PDF accessibility requirements — including tags, reading order, alt text, form fields, language specification, and compliance standards.

What is PDF Accessibility?

PDF accessibility ensures that PDF documents are usable by people with disabilities who rely on screen readers, screen magnifiers, and other assistive technologies. An accessible PDF includes proper tags, reading order, alt text for images, and form fields that can be navigated via keyboard.

The PDF/UA (Universal Accessibility) standard (ISO 14289) defines technical requirements for accessible PDFs, and WCAG 2.1 applies to PDFs when they are used as web content.

Accessible PDF files are essential for compliance with ADA, Section 508, EAA, and other accessibility laws.

PDF Accessibility Standards — WCAG 2.1 & PDF/UA

PDF accessibility standards are defined by two primary frameworks:

WCAG 2.1 Level AA for PDFs

When PDFs are used as web content, they must meet WCAG 2.1 PDF accessibility requirements:

WCAG compliant PDF documents follow these success criteria. WCAG pdf compliance is required under ADA and Section 508.

PDF/UA (ISO 14289)

PDF/UA (Universal Accessibility) is the international standard for accessible PDFs. PDF/UA compliance requires:

PDF/UA is the gold standard for accessible PDF documents.

ADA Compliance for PDF Documents

ADA compliance for PDF documents is required under ADA Title III. Courts have ruled that PDF documents offered on websites must be accessible to people with disabilities.

ADA compliant PDF files must meet WCAG 2.1 Level AA standards. ADA accessible PDF documents include:

ADA pdfs that are inaccessible have been the subject of numerous lawsuits, particularly in banking, healthcare, and education sectors.

Section 508 PDF Requirements

Section 508 PDF compliance is required for all federal agencies and organizations receiving federal funding. Section 508 compliant PDF documents must meet WCAG 2.1 Level AA and PDF/UA standards.

508 compliant PDF requirements include:

508 compliance for documents is enforced by the US Access Board and can result in loss of federal funding for non-compliance.

European Accessibility Act (EAA) PDF Requirements

The EAA requires PDF documents offered as part of covered services (e-books, banking statements, healthcare forms) to be accessible. EAA pdf requirements align with WCAG 2.1 Level AA and PDF/UA.

Making PDFs accessible for e-book platforms is a specific EAA requirement. Non-compliant PDFs can result in fines up to €100,000.

How to Make PDFs Accessible — Step by Step

Making PDFs accessible involves several steps. How to make PDFs ADA compliant follows the same process:

Step 1: Create Source Document Accessibly

Creating accessible PDFs starts with the source document. Creating accessible PDFs in InDesign or creating accessible PDFs in Word is the best approach:

Step 2: Export as Tagged PDF

From Adobe InDesign, check "Create Tagged PDF" during export.
From Microsoft Word, check "Document structure tags for accessibility".

Step 3: Run Accessibility Check in Adobe Acrobat

Use Adobe Acrobat accessibility tools to check your PDF:

  1. Open PDF in Adobe Acrobat Pro DC
  2. Go to Tools → Accessibility → Full Check
  3. Review results and fix issues
  4. Use Accessibility Setup Assistant Adobe Acrobat to guide you

Acrobat accessibility features include:

Step 4: Fix Common Issues

PDF Tags — The Foundation of PDF Accessibility

Tagged PDF is the foundation of PDF accessibility. Tags provide structure that screen readers can interpret:

Indesign tagged PDF export ensures proper tagging. Indesign accessibility features include tagging, alt text, and reading order controls.

Acrobat screen reader uses these tags to navigate and read PDF content. Adobe pdf screen reader compatibility depends on proper tagging.

Screen Reader Compatibility for PDFs

PDF screen reader compatibility ensures blind users can access PDF content. Popular screen readers for PDFs include:

PDF reader for blind users must be able to interpret tags, alt text, and form fields. Adobe reader aloud (Read Out Loud) is a built-in screen reader in Adobe Acrobat Reader.

Google Docs screen reader support for PDFs works with ChromeVox and other screen readers.

Adobe reading untagged document warning appears when a PDF has no tags — screen readers cannot interpret untagged documents properly.

VPAT (Voluntary Product Accessibility Template)

VPAT (Voluntary Product Accessibility Template) is a document that explains how a product (including PDFs) meets accessibility standards.

VPAT 2.4 and VPAT 2.4 example are commonly searched for federal procurement. VPAT 2.1 and VPAT 2.3 are earlier versions.

Section 508 VPAT is required for government vendors. Completed VPAT example shows how to document compliance. Adobe VPAT and deque vpat are vendor examples.

Docusign vpat is an example for e-signature platforms. CommonLook PDF VPAT is available for their remediation tools.

VPAT 508 refers to VPAT for Section 508 compliance. Vpat 2.4 example is the current version.

PDF Remediation — What It Is and When You Need It

PDF remediation is the process of fixing inaccessible PDFs. PDF remediation services are available for organizations with large document libraries.

You need PDF remediation when:

PDF accessibility services include remediation, testing, and consulting. Accessible pdf services help organizations achieve compliance.
