It's a vital tool for anyone who creates or works with PDF documents, as it helps identify and resolve accessibility issues. Accessibility issues in PDFs can make them difficult or even impossible to navigate for people using screen readers, assistive technologies, or who have visual impairments.
PAC 3 assists in making PDFs more accessible by:
- Analyzing PDFs for accessibility compliance: It identifies issues like missing alt text for images, improper heading structure, and lack of logical reading order.
- Providing actionable feedback: PAC 3 offers detailed reports outlining the specific problems found and how to fix them.
- Guiding users through the remediation process: It suggests tools and techniques for fixing accessibility issues, making the process easier and more efficient.
Key Features of PAC 3
PAC 3 offers several features that make it a robust accessibility checker:
- Comprehensive Analysis: It examines a wide range of accessibility aspects, including text content, images, tables, and forms.
- Support for WCAG 2.1: PAC 3 is aligned with the Web Content Accessibility Guidelines (WCAG) 2.1, ensuring your PDFs meet current accessibility standards.
- User-Friendly Interface: PAC 3 boasts a simple and intuitive interface, making it easy for both novice and experienced users to understand and navigate.
- Multiple Report Formats: You can choose from various report formats, including HTML, text, and XML, to best suit your needs.

Tips for Creating Accessible PDFs
In addition to using PAC 3, follow these tips to create accessible PDFs from the outset:
- Use Headings and Structure: Organize your document with logical headings (H1, H2, etc.) to create a clear structure for screen readers.
- Provide Alt Text for Images: Every image should have descriptive alt text that conveys the image's content and purpose.
- Ensure Logical Reading Order: Make sure the reading order of text and images is logical and follows the flow of your content.
- Use Tables Properly: Use tables for data presentation, not layout, and ensure they are properly formatted.
- Check Document Properties: Set the language, author, and document title correctly in the document properties.
Example: Addressing Accessibility Issues in a PDF
Let's say you have a PDF containing an image of a graph without any alt text. PAC 3 will flag this as an accessibility issue. To remediate this:
- Identify the Issue: PAC 3 will indicate the image in question and mention the missing alt text.
- Add Alt Text: Use your PDF editor to add alt text to the image. The alt text should describe the graph's content, such as "Line graph showing sales trends for the last year."
- Re-run PAC 3: Run PAC 3 again to verify the issue has been resolved.
Conclusion
PAC 3 is a powerful tool that can significantly improve the accessibility of your PDF documents. By using this tool, you can ensure your information is accessible to a wider audience, including those with disabilities. Regularly checking your PDFs using PAC 3 will help you create and maintain documents that are inclusive and welcoming to all.
