PDFix – PDF Accessibility Software

PDFix develops a suite of PDF accessibility tools used by accessibility specialists, enterprise compliance teams, and software developers. The product line covers every stage of the PDF accessibility workflow – from initial auto-tagging and manual remediation to validation, batch processing, and programmatic API access.

Organizations That Rely on PDFix for PDF Accessibility Compliance

PDFix tools are deployed by government agencies, financial institutions, courts, and universities that require reliable, auditable PDF accessibility compliance at scale.

PDFix is an active member of the PDF Association – the international organization that develops and maintains ISO standards for PDF technology, including PDF/UA (ISO 14289). PDFix team members contribute directly to the working groups that define how PDF accessibility standards are written and implemented.

Standards Working Group Involvement

These contributions ensure PDFix technology reflects the latest PDF/UA specifications – developed alongside the same experts who author the ISO standards our tools validate against.

More than 80% of non-HTML enterprise content is delivered as PDF – reports, invoices, statements, official documents. Yet most PDFs are inaccessible to users who rely on screen readers, screen magnifiers, and other assistive technologies. PDFix exists to close this gap: making PDF/UA compliance achievable at scale, without requiring expert manual work on every document.

We believe documents that serve everyone – regardless of disability – should be the standard, not the exception.
