When it comes to creating accessible PDFs, there may be an assumption that simply making a file readable by assistive technology is enough. If you want to show clients or stakeholders that your documents are genuinely accessible, you need to take it a step further, ensuring your files meet recognized accessibility standards. Achieving this can be trickier than it seems, but understanding the process makes it far more manageable. Many accessibility issues in PDFs appear not because of complex technical errors, but because documents were never designed with accessibility in mind from the beginning.

Before confirming that a PDF is accessible, an understanding of what “accessible” really means must be reached. Accessible PDFs aren’t just readable, they must be structured and compatible with assistive technologies like screen readers. If a file begins as a properly structured Word document or presentation, the process of converting it into an accessible PDF becomes significantly easier. When structure is missing at the source, remediation later can take much longer. To ensure this, compliance with recognized standards such as WCAG is critical. These standards provide a benchmark for accessibility, making it clear what features a compliant document should include, from proper headings to alternative text for images.
Tools for PDF Accessibility
Automated checkers are a helpful starting point as they scan PDFs for common issues and highlight areas that need improvement. Accessibility checkers can quickly identify missing tags, reading order problems, or images lacking descriptions.
Relying solely on automated tools isn’t enough as not all issues can be detected by a checker.
Is the alternative text descriptive and similar to the content on the PDF?
Does the reading order make sense for a screen reader user?
Are tables and images structured correctly for navigation?
Screen readers, magnifiers, and other assistive tools reveal issues that checkers might miss, ensuring your PDFs are usable by real people, not just machines. Testing documents with assistive technology provides insight into how users actually interact with the material, often uncovering barriers that automated scans cannot identify.
Issues You May Experience
Several common problems appear frequently in inaccessible PDFs. Being aware of them can help creators avoid issues before they appear.
– Missing or inaccurate text for images and graphics
– Incorrect heading structures or skipped heading levels
– Color contrast issues in graphics or charts
– Improper reading order for different layouts
Being aware of these pitfalls, and proactively building your documents with accessibility in mind reduces the need for extensive remediation later.
Another common issue occurs when documents rely heavily on visual formatting rather than having the proper structure. For example, text may appear visually organized on the page but lack the underlying structure needed for screen readers to interpret it correctly. The key to creating compliant PDFs isn’t just checking boxes, it’s building documents intentionally. Proper use of headings, consistent structure, and descriptive images all contribute to accessibility compliance. When you approach document creation with purpose, compliance becomes a natural byproduct rather than an afterthought. Even small changes, such as consistently using heading styles or adding clear descriptions to images, can make a substantial difference in how accessible a document becomes.
Compliance is the foundation, but true accessibility goes further. By combining automated checking, assistive technology testing, and intentional document design, your PDFs will be both WCAG compliant and genuinely usable by your audience. That’s the ultimate goal: documents that meet the standard and meet real user needs. When accessibility is approached with this mindset, documents become easier to navigate, easier to understand, and more inclusive for everyone who needs to use them.
