Best Tools for Creating Accessible Tagged PDFs
Question details
The user is seeking third-party software or plugins to automate the time-consuming process of correcting tags, reading order, and accessibility errors in PDFs.
- Product
- Device & OS
- not provided
- Scenario
- Automating the remediation and validation of PDF tags to meet accessibility standards.
- Observed behavior
- Manual remediation of PDF accessibility errors and tag trees takes several hours per document, necessitating a more automated solution.
Whenever possible, fix accessibility issues such as reading order and alternative text in the original source document (like Microsoft Word or InDesign) before exporting it to PDF.
Use Specialized PDF Accessibility Checkers and Remediation Plugins
Automate and validate your PDF structure using dedicated third-party accessibility tools and plugins.
While automated tools significantly reduce the time spent on PDF remediation, they are not foolproof. Complex layouts, nested tables, and decorative images often require human judgment to ensure true accessibility compliance under WCAG and PDF/UA standards.
Use software like axesWord during the document creation phase to automatically generate highly compliant PDF tags directly from Microsoft Word.
Apply tools like CommonLook PDF Validator and Fix to automatically identify and repair common structural issues and tagging errors in existing PDFs.
Open your document in Adobe Acrobat Pro, navigate to the 'Accessibility' tool, and run the 'Full Check' to identify baseline reading order and tag structure issues.
Manually review the tag tree, reading order panel, alternative text for images, and complex table headers to correct nuances that automated tools miss.
Use the free PDF Accessibility Checker (PAC) to run a final validation scan against universal PDF/UA requirements.
Create Well-Structured Documents with WPS Office
WPS Office provides powerful, easy-to-use tools to structure your text documents with proper headings, alternative text, and clear reading orders. Creating an accessible foundation in WPS Writer makes exporting high-quality PDFs seamless and reduces the need for extensive post-export tagging.
- 1. Apply Heading Styles: Open your document in WPS Writer and use the built-in 'Styles' pane to apply logical heading levels (Heading 1, Heading 2) to organize your text.
- 2. Add Alternative Text: Right-click any image or graphic in your document, select 'Picture Properties', and enter descriptive text in the Alternative Text field.
- 3. Format Tables with Headers: Use the 'Table Tools' to ensure your data tables have clearly defined header rows for better structural readability.
- 4. Export to PDF: Go to the 'Menu', select 'Export to PDF', and save your properly structured document as a PDF file.
Frequently Asked Questions
What is a tagged PDF?
A tagged PDF contains hidden structural metadata (tags) that define the document's elements, such as headings, paragraphs, and tables. These tags determine the logical reading order, making the document accessible to assistive technologies like screen readers.
Why isn't automated PDF remediation fully accurate?
Automated tools rely on algorithms that struggle to infer contextual nuances, such as whether an image is informative or purely decorative, or how to correctly sequence the reading order in complex, multi-column layouts. Manual verification is always required to ensure compliance.
What are the WCAG and PDF/UA standards?
PDF/UA (Universal Accessibility) is a specific ISO standard ensuring PDF documents are accessible to people with disabilities. WCAG (Web Content Accessibility Guidelines) is a broader set of recommendations for making digital content, including web-hosted PDFs, highly accessible.
