Frequently Asked Questions

What is PDF/UA compliance and why does it matter?

PDF/UA (ISO 14289) is the international standard for universally accessible PDF documents. It ensures PDFs are fully readable by assistive technologies including screen readers, Braille displays, and voice controls. Non-compliant PDFs can create legal liability under ADA, Section 508, and the European Accessibility Act. PDFix automates the remediation process to make PDFs PDF/UA compliant efficiently.

How does PDFix automate PDF accessibility?

PDFix uses AI-driven layout recognition to automatically detect document structure, reading order, tables, lists, headings, and annotations. It then generates the correct PDF/UA tag structure, drastically reducing the time needed for manual accessibility remediation – cutting effort by up to 80% on most document types.

What accessibility standards does PDFix support?

PDFix supports PDF/UA (ISO 14289), WCAG 2.1 AA, ADA Title II (including 2026 deadline requirements), Section 508 for federal agencies, and the European Accessibility Act (EAA). Both Desktop and SDK products cover all four major standards.

Can PDFix process large volumes of PDFs in bulk?

Yes. PDFix Desktop Pro includes batch processing for bulk PDF remediation. The PDFix SDK enables enterprise-scale automation by integrating directly into existing document workflows, CMSes, and document generation pipelines — processing thousands of documents automatically.

Is there a free version of PDFix? Can I try it before buying?

Yes – you can download PDFix Desktop and PDFix SDK for free and use all features without any time limit or registration. The only limitation in the free trial is that saved documents carry a watermark. This lets you fully evaluate auto-tagging, batch processing, validation, and every other feature before purchasing a license.

PDFix Desktop Lite is a permanently free PDF accessibility checker – no purchase needed. It includes the industry-supported veraPDF validator, which is the standard engine used across the PDF accessibility community. It supports all major accessibility standards and profiles including PDF/UA, WCAG 2.1, WCAG 2.2, Section 508, and the European Accessibility Act, and lets you navigate directly to each detected issue in your document.

What is ADA Title II 2026 accessibility deadline?

Under the updated ADA Title II rule, state and local government entities and public universities must meet WCAG 2.1 Level AA standards for digital content, including PDFs. Most compliance deadlines fall in 2026. PDFix provides specific workflows designed to help organizations meet these deadlines efficiently and at scale.
