Accessible PDFs: How to Create and Use Them

Have you ever opened a PDF and wondered whether everyone can actually read it? Accessible PDFs are designed so that people who use screen readers or other assistive technologies can navigate and understand the content just as easily as anyone else. Unlike a regular PDF, an accessible PDF includes proper tags, alt text for images, a logical reading order, and searchable text.

As more forms, reports, and resources move online, digital accessibility is no longer optional. Organizations need to know how to make a PDF accessible, how to convert existing files, and how to maintain accessibility in translated documents. In this guide, we'll walk through each step clearly and practically. We'll also explain how MotaWord supports accessible PDF translations, especially when you're working with official multilingual documents.

What Is an Accessible PDF and Why It Matters

An accessible PDF is a document built with structure and usability in mind so that people using screen readers and other assistive technologies can read and navigate it effectively. It is not just a visually clean file. A true accessible PDF includes proper tags for headings, paragraphs, lists, and tables, meaningful alt text for images, a logical reading order, searchable text, and a defined document language.

Tags act like a map behind the scenes. They tell assistive software what a heading is, what body text is, and how sections relate to each other. Logical reading order makes sure content is read in the correct sequence. Searchable text, rather than scanned images of text, allows users to copy, search, and interpret content accurately. Setting the document language helps screen readers pronounce words correctly.

Accessible PDF documents matter across industries. Healthcare providers share patient forms. Universities publish course materials. Government agencies distribute public resources. Businesses send contracts and reports. In all these cases, accessibility supports usability, inclusion, and broader reach.

Standards such as WCAG and Section 508 outline expectations for digital accessibility, including PDFs. While legal requirements vary by organization and region, learning how to make a PDF accessible is a practical step toward clearer communication and equal access for everyone. If your files are also used in formal workflows, our guide on official document translation is a useful companion.

Accessibility Standards: WCAG and Section 508 Explained

When creating accessible PDFs, two major frameworks guide best practices: WCAG and Section 508.

WCAG, or the Web Content Accessibility Guidelines, is an international set of recommendations for making digital content more accessible to people with disabilities. Although originally written for websites, WCAG also applies to documents, including any accessible PDF you publish online.

Section 508 is a U.S. law that requires federal agencies to make their electronic and information technology accessible. This includes websites, software, and PDF documents shared with the public. Many private organizations follow Section 508 as a benchmark, especially when working with government entities.

For document creators, these standards translate into practical expectations when creating accessible PDFs:

• Text must be readable and selectable, not just scanned images
• Headings, lists, and tables must be properly tagged
• Content must follow a logical reading order
• Images must include meaningful alt text
• Files must be compatible with screen readers and other assistive technologies

Following WCAG and Section 508 helps make sure your PDFs are usable, compliant where required, and genuinely inclusive.

Accessible PDF vs. Regular PDF: Key Differences

At a glance, an accessible PDF and a regular PDF may look identical. The difference appears when someone tries to navigate the file with a screen reader or keyboard only.

A regular PDF is often just a visual layout. It may lack tags, proper structure, or searchable text. An accessible PDF, on the other hand, is built with underlying structure that assistive technologies can interpret. That structure is the core difference between regular and accessible PDF formats.

In a standard file, a screen reader might read text out of order, skip images, or fail to recognize headings. In an accessible version, headings are tagged, images include alt text, and the reading order follows a logical flow. This directly affects usability for people with visual or cognitive disabilities.

Understanding the distinction helps you create documents that everyone can use confidently.

Creating Accessible PDFs from the Start: Best Practices

If you're working in Word, Google Docs, or InDesign, the easiest way to support accessibility is to build it in from day one. Here's a practical checklist for creating accessible PDFs that work smoothly with screen readers and other assistive tools.

1. Use built-in heading styles

Apply official heading styles such as Heading 1, Heading 2, and so on. Do not just bold or enlarge text. These styles create structural tags that screen readers rely on to understand sections and navigation.

2. Write meaningful alt text for images

Add alt text to every informative image, chart, or graphic. This makes sure users who cannot see the image still understand its purpose and context. Decorative images can be marked as such.

3. Structure tables correctly

Use simple tables with defined header rows. Avoid merged or split cells when possible. Properly structured tables help screen readers interpret data row by row and column by column.

4. Set the document language

Define the primary language in your document settings. This allows screen readers to pronounce words accurately and switch languages when needed.

5. Make sure text is real and selectable

Avoid relying on scanned images of text. Always work with actual typed content. If you must use scanned material, apply OCR before finalizing. Searchable text is essential in accessible PDF documents.

6. Check reading order before exporting

Review the layout to confirm the content flows logically from top to bottom. A correct reading order is a key part of how to make a PDF accessible.

By following this checklist, you make accessible PDF documents part of your normal workflow instead of an afterthought.

Converting a Regular PDF to an Accessible PDF

Already have a finished file? You can still convert a PDF to an accessible PDF with the right tools and a careful review process. Here's a streamlined step-by-step approach using Adobe Acrobat Pro.

1. Run OCR if the file is scanned

If your document is a scanned image, start with Optical Character Recognition. OCR converts images of text into searchable, selectable content. This is essential in any PDF to accessible PDF workflow.

2. Use the accessibility tools

Open the Accessibility panel in Acrobat and run a full accessibility check. This will flag missing tags, reading order problems, and other structural issues.

3. Add and review tags in the Tags pane

Open the Tags pane to inspect the document structure. Make sure headings, paragraphs, lists, and tables are properly tagged. Adjust or add tags where needed. Accurate tagging is central to creating accessible PDFs.

4. Fix the reading order

Use the Reading Order tool to confirm that content flows logically. Screen readers rely on this sequence to present information correctly.

5. Add alt text to images

Provide meaningful descriptions for images, charts, and graphics. Decorative images can be marked as artifacts.

6. Re-run the accessibility checker

Address each flagged issue, including missing metadata or contrast warnings.

7. Test with a screen reader

Use tools like NVDA or JAWS to experience the document as a user would.

If a file is heavily scanned, poorly structured, or visually complex, it may be more efficient to recreate it from the source rather than repair it piece by piece.

Common Mistakes to Avoid When Working with Accessible PDFs

Even with the right tools, it's easy to overlook details that affect your accessible PDF. Many issues happen when accessibility is treated as a final checkbox instead of part of the workflow.

One common mistake is using scanned images of text without applying OCR. If text is not searchable and selectable, screen readers cannot interpret it properly. Another frequent issue is missing alt text for images, charts, or infographics. Without descriptions, important information is simply lost.

Incorrect reading order is also a major problem. If content is visually arranged in columns or text boxes but not properly structured, assistive technology may read it in a confusing sequence.

Here are other mistakes to watch for when creating accessible PDFs:

• Relying only on visual formatting instead of built-in heading styles
• Skipping manual tag review after auto tagging
• Ignoring document language settings
• Not testing with a screen reader

If you're learning how to make a PDF accessible, prevention is key. Build structure carefully, review tags manually, and always test before sharing.

Accessible PDF Translations with MotaWord

Creating accessible PDF documents is only part of the equation. If you translate that content into another language, accessibility must be preserved. Otherwise, the structure, tags, and reading order can break during the process.

At MotaWord, we provide translations delivered as fully accessible PDF files upon request. This means your translated document includes proper tagging, meaningful alt text, a defined document language, and logical reading order. We do not simply translate the visible text. We help make sure the final accessible PDF remains compatible with screen readers and assistive technologies.

This is especially valuable for legal, medical, and educational organizations that regularly publish contracts, patient forms, reports, or course materials. In these fields, clarity and equal access matter across every language version.

If you are not sure whether your project calls for a certified workflow or a standard one, our article on certified vs. general translation can help you decide. For a broader overview of remote workflows, delivery, and document handling, you can also read our guide to online document translation and certification.

If you already have a compliant file, we can maintain its accessibility during translation.

FAQ: Accessible PDFs

What is the difference between a PDF and an accessible PDF?

The main difference is structure. A regular PDF often focuses only on visual layout. An accessible PDF includes proper tagging for headings, paragraphs, lists, and tables, along with meaningful alt text and a logical reading order.

In short, accessible PDF documents are built so screen readers and other assistive technologies can interpret them correctly. Without tags and defined structure, a standard PDF may be read out of order or not fully read at all.

How do I know if my PDF is accessible?

Start by using the Accessibility Checker in Adobe Acrobat Pro. It scans your file and flags issues such as missing tags, absent alt text, or reading order problems. This gives you a technical overview of your document's accessibility status.

However, automated tools are not enough. For a more accurate test, open the file with a screen reader like NVDA or JAWS and navigate through it using only a keyboard. If headings, lists, and tables make sense and the content flows logically, your PDF is likely accessible.

Can scanned PDFs be made accessible?

Yes, but they require extra work. A scanned file is essentially an image, so the first step is running OCR. Optical Character Recognition converts images of text into searchable, selectable content.

After OCR, you still need to add tags, define reading order, and include alt text. Converting a scanned file almost always requires manual review to make sure the content is accurate and properly structured.

Do translated PDFs need accessibility features too?

Absolutely. Accessibility should be preserved across all language versions. When translating accessible PDF documents, the tags, reading order, alt text, and document language settings must remain intact.

If accessibility is ignored during translation, the final file may no longer function properly with assistive tools. That's why maintaining accessibility standards throughout the translation process is essential for consistent, inclusive communication in every language.

Making Accessibility a Standard, Not an Afterthought

Accessible documents are no longer a niche requirement. They are a growing expectation across industries and audiences. Whether you are creating accessible PDFs from scratch, improving an existing file, or translating content into new languages, the goal is the same: equal access to information.

Accessible PDF documents support usability, compliance where required, and a stronger connection with your audience. They show that your organization values clarity and inclusion, not just visual presentation.

The most effective approach is to build accessibility into every document workflow from the start. Use structured templates. Train your teams. Review files before publishing. And when translating, make sure accessibility is preserved, not lost.

If you need support delivering translated accessible PDF documents, MotaWord can help you combine accuracy, structure, and accessibility in one seamless process.

Make accessibility your standard practice, not a last-minute fix.
