In today’s digital landscape, the ability to create accessible PDFs is more important than ever. Whether you’re sharing reports, brochures, or instructional materials, ensuring that your PDF documents are accessible to all users—including those with disabilities—is not just a good practice, but often a legal requirement. In this guide, we’ll walk you through the steps to create accessible PDF documents that meet the Web Content Accessibility Guidelines (WCAG) standards.

1. Start with an Accessible Source Document

The first step in creating an accessible PDF is to begin with an accessible source document. Whether you’re using Microsoft Word, Google Docs, or another word processor, ensure that your document is structured correctly before converting it to a PDF. Here are some best practices:

Use Proper Headings: Organize your content with proper heading levels (H1, H2, H3, etc.). This structure not only helps all users navigate the document but also ensures that screen readers can interpret the content correctly.

Add Alternate Text to Images: Every image in your document should have alternate text that describes the image’s content. This description is crucial for users who rely on screen readers to understand visual elements.

Create Descriptive Links: Use descriptive link text instead of generic phrases like “click here.” For example, “Visit our Accessibility Resources page” is more informative than “Click here for more info.”

Use Lists and Tables Properly: When creating lists, use the built-in bullet or number features. For tables, ensure they are simple and include header rows that are marked as such in your source document.

Set a Document Title: Ensure that your document has a proper document title in the metadata. This helps with accessibility and proper identification of content, assisting screen readers and improving the overall usability of PDF files.

2. Convert to PDF Using the Right Tools

Once your source document is accessible, the next step is to convert it into a PDF file. Not all PDF converters are created equal, so it’s important to use a tool that preserves the accessibility features of your source document. Here are some recommendations:

Adobe Acrobat Pro: This is the industry standard for creating accessible PDFs. When saving your document as a PDF in Adobe Acrobat Pro, use the “Save As” function and select “PDF/A” for archiving, which is optimized for accessibility.

Microsoft Word: If you’re using Microsoft Word, use the “Save As” or “Export” function and select “PDF” as the file format. Make sure to check the option “Best for electronic distribution and accessibility” to ensure accessibility features are preserved.

Google Docs: In Google Docs, use the “Download” function and select “PDF Document.” While Google Docs does a reasonable job of preserving accessibility, double-check your document in a PDF editor afterward.

Interactive PDF Forms: Transform your documents into interactive PDF forms by incorporating form fields and various controls. Customize these forms with descriptions for each element to enhance usability.

3. Check and Enhance PDF Accessibility

After converting your document to a PDF, it’s crucial to verify and enhance its accessibility. Adobe Acrobat Pro offers robust tools for this purpose:

Use the Accessibility Checker: Open your PDF in Adobe Acrobat Pro and run the Accessibility Checker (Tools > Accessibility > Full Check). This tool will scan your document for common accessibility issues, such as missing alt text, improperly tagged elements, or reading order problems. Ensure that scripts do not hinder the functionality of assistive technologies, thereby ensuring that all users can access content effectively.

Tagging: Tags are essential in PDFs as they define the structure and reading order of the content. Ensure that headings, lists, tables, and other elements are correctly tagged. If the document lacks proper tags, use the “Autotag Document” feature, then manually review and adjust tags as needed to improve document accessibility for assistive technologies.

Reading Order: Verify that the reading order of your document is logical. The Order panel in Adobe Acrobat Pro allows you to view and adjust the sequence in which content is read by screen readers. A clear structure and logical reading order enhance accessibility for users, particularly those using screen readers.

4. Add Descriptive Metadata

Metadata provides additional context about your document and is helpful for users who rely on screen readers:

Title and Language: Add a descriptive title and specify the document's primary language. This helps screen readers accurately interpret the content.

Document Properties: In Adobe Acrobat Pro, you can add metadata by going to File > Properties. Fill in the Title, Author, Subject, and Keywords fields with relevant information.

5. Test Your PDF for Accessibility

Before finalizing your PDF files, test them to ensure they meet accessibility standards:

Screen Reader Testing: Use a screen reader such as NVDA (free) or JAWS (paid) to navigate through your document. Pay attention to how the content is read and whether any elements are skipped or incorrectly described.

Manual Review: Conduct a manual review by navigating through the document using only the keyboard. Ensure that all interactive elements, like links and form fields, are accessible and usable without a mouse.

6. Keep Accessibility in Mind for Future Updates

Accessibility is an ongoing process. As your documents evolve, continue to apply these practices to ensure they remain accessible. Regularly update your knowledge of accessibility standards, as they may change over time.

Conclusion

Creating accessible PDF documents is a critical step in making your digital content available to everyone. By following these guidelines and utilizing the right tools, you can ensure that your PDFs meet accessibility standards and provide an inclusive experience for all users. Remember, accessibility is not just a checkbox—it’s a commitment to inclusivity and equal access for everyone.
