Why Acrobat Accessibility Checker Reports Differ & How to Fix Them
Question details
The user needs to understand why the Adobe Acrobat Accessibility Checker yields inconsistent results on different computers for the same PDF and how to resolve these discrepancies.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Running an automated accessibility check on a PDF document across multiple devices or workstations.
- Observed behavior
- The Accessibility Checker generates different error reports, identifying varying accessibility issues (like alt text or headings) depending on the computer used.
Ensure that all computers testing the PDF are running the exact same version of Adobe Acrobat, as updates frequently change how automated accessibility standards are applied.
Standardize Full Check Configuration Settings
The most common reason for report discrepancies is differing configurations in the Full Check settings. Aligning these options guarantees a consistent testing environment.
The Accessibility Checker in Acrobat relies on customizable parameters. If one computer checks for all WCAG 2.0 standards while another only checks basic document structure, the resulting reports will naturally conflict. Standardizing these settings is essential for collaborative workflows.
Navigate to the Tools menu in Acrobat and open the 'Accessibility' toolset.
Click on 'Full Check' (or 'Accessibility Check' in newer versions) from the right-hand panel to open the configuration dialog.
Carefully review all selected checking options, including the selected standard, document categories, and structural rules.
Ensure that every checkbox and dropdown matches identically between the two computers, then click 'Start Checking' to generate a standardized report.
Review and Fix Identified Accessibility Issues
Once the reports are standardized, use the built-in Accessibility Checker panel to systematically address the specific errors found in your PDF.
Easily Edit and Standardize PDFs with WPS Office
While automated accessibility checks require precise configuration, editing the underlying PDF document shouldn't be complicated. WPS PDF offers a highly efficient way to modify PDF text, manage document properties, and ensure your files are cleanly structured before running compliance checks.
- 1. Open the PDF: Launch WPS Office and open your PDF document using the WPS PDF tool.
- 2. Edit Document Content: Navigate to the 'Edit' tab to directly modify text, update headings, and adjust image properties.
- 3. Convert for Advanced Checking: If needed, use the 'PDF to Word' feature to convert the file and utilize Word's native accessibility checker.
- 4. Export as PDF: Save your optimized document and easily export it back to a standard PDF format.
Frequently Asked Questions
Why does the accessibility checker say my PDF needs a manual check?
Automated tools cannot verify everything. Certain accessibility criteria, such as logical reading order and proper color contrast, require a human review to ensure they make sense to a screen reader user.
Does fixing an issue in the checker guarantee WCAG compliance?
No. Passing an automated checker is a great first step, but true WCAG or Section 508 compliance always requires manual verification, including testing the document with assistive technologies like screen readers.
What happens when I click 'Explain' on an accessibility error?
Clicking 'Explain' redirects you to official documentation related to that specific error. It provides context about why the rule exists and offers step-by-step instructions for manually correcting the structural or formatting issue.
Can different software versions cause variations in PDF accessibility reports?
Yes. If one computer uses an older version of the software, it might be checking against outdated accessibility standards or missing newer automated checks, resulting in a significantly different report.
