ConvertAPI’s PDF Accessibility Automation helps enterprises turn large volumes of PDFs into accessible, standards-ready documents—without the manual grind. Our engine analyzes layout and semantics to build a complete tagged PDF: headings and reading order, lists, tables with header scope, figures and links, plus properly labeled form fields. For scanned content, built-in OCR reconstructs text and structure so screen readers and other assistive technologies can navigate reliably, boosting usability and trust.

Designed for compliance programs, the workflow targets PDF/UA and aligns with WCAG/EN 301 549, helping organizations prepare for the EU Accessibility Act 2025. Automated checks surface issues early, while validation reports make it easy to review and remediate edge cases. Human approval steps remain available for items like complex tables or nuanced alt text, balancing speed with conformance.

Automatic Structure Detection & Tagging

Headings, lists, tables, figures, footnotes, reading order, language - all mapped into a compliant PDF structure tree.

Tabular Data Intelligence

Detect tables and set header scope and associations to improve accessibility and reliable export.

Forms & Annotations

Tag form fields with labels, roles, and logical tab order; preserve keyboard navigation.

OCR + Remediation for Scans

Perform OCR, rebuild structure, and export a tagged, screen‑reader‑friendly PDF.

PDF/UA Compliance

Built‑in checks with export to PDF/UA files; optional PAC 2024 cross‑check in QA.

Enterprise Controls

Enterprise-grade security with ISO 27001 certification, HIPAA & GDPR compliance, audit logs, and regional processing.

How it Works

You can remediate millions of documents, and receive the conformant PDF/UA. The result is faster, more consistent and cleaner, allowing more accurate data extraction.

Upload & Ingest

Securely bring in digital and scanned PDFs.
Connect storage or apps and stream files to the pipeline. We fingerprint files, detect languages, and prep scans for OCR so downstream tagging is reliable.

Tag & Repair Automatically

Build a standards‑compliant structure tree.
We map roles to PDF/UA, add landmarks, associate table headers, set list semantics, fix link annotations, and generate alt‑text suggestions for images.

- Headings (H1–H6), lists, tables, figures, footnotes
- Form labels and logical tab order
- Alt‑text suggestions with “needs review” flags

Review & Validate

Triage edge cases and run conformance checks.
A lightweight reviewer lets you adjust reading order, approve alt text, and resolve issues. Automated checks highlight what’s left to fix.

- Visual representation of errors
- PDF/UA & EN 301 549 aligned checks
- Export a validation report for QA

A Key Tool for Regulatory Compliance

EAA 2025

EU Accessibility Act

We help businesses comply with EAA now in effect across the EU; supports access to products and services for people with disabilities.

PDF/UA

ISO 14289‑1 & 14289‑2

Generate PDF/UA conformant documents with accessible PDF requirements; “tagged PDF” enables predictable reading order and navigation.

Section 508

Section 508 (U.S.)

Make sure your documents comply with US Federal guidance and resources for accessible PDFs to ensure the documents are accessible to people with disabilities.

Use Cases by Industry

Our PDF Accessibility tool provides a well‑tagged structure (headings, lists, tables, figures) improves downstream parsing and table/field capture for analytics and AI.

  • Finance and Banking

    Accessible PDFs turn statements, disclosures, onboarding forms, and loan documents into assets everyone can read with screen readers and other assistive tech. Automated tagging (headings, tables with header scope, lists, links) also improves downstream data extraction - useful for reconciliations, analytics, and fraud workflows.

    From a risk and compliance angle, banks face growing regulatory and reputational pressure to make digital services accessible. Typical targets include PDF/UA conformance and WCAG-aligned requirements (via EN 301 549 in the EU). The EU Accessibility Act (EAA) 2025 explicitly covers many consumer financial services, while in the U.S. the ADA is commonly applied to online banking and documents.

  • Legal Services

    Firms and courts distribute filings, contracts, exhibits, and discovery bundles as PDFs. Automating structure tagging and reading order ensures equal access for clients and the public, and reduces manual remediation costs on high-volume matters. Accurate table and form tagging improves e-discovery searchability and reduces rework when exporting facts/tables to case management tools.

    Compliance expectations typically map to PDF/UA and WCAG. In the EU, EN 301 549 and the EAA 2025 push accessibility across legal services delivered to consumers. In the U.S., law firms operating as places of public accommodation fall under the ADA; public-sector clients often require conformance comparable to Section 508 standards.

  • Healthcare and Insurance

    Member communications (EOBs, policy docs), patient instructions, and prior-authorization forms must be readable by assistive technologies. Automated OCR + tagging turns scans into navigable, tagged PDFs and improves comprehension for patients and caregivers. Clean structure also boosts extraction accuracy for claims, utilization review, and quality programs.

    Regulatory drivers include ADA obligations and Section 1557 of the Affordable Care Act (effective communication and accessibility in health programs). In Europe, EN 301 549 and the EAA 2025 extend accessibility expectations to consumer-facing health and insurance services. Privacy rules like HIPAA/GDPR still apply to handling content; accessibility ensures users can actually consume it.

  • Education and Research

    Syllabi, course packets, assessments, library reserves, and research outputs are often PDF-based. Automated remediation produces tagged PDFs with correct reading order and table/figure semantics so students using screen readers get equitable access. For archives and institutional repositories, consistent tagging improves searchability and data mining.

    Public universities and K-12 districts in the U.S. have duties under ADA Title II and Section 504; many follow WCAG-based standards in practice. In the EU, the Web Accessibility Directive and EN 301 549 govern public-sector digital content; EAA 2025 increases expectations for services beyond the public sector (e.g., private providers and EdTech vendors).

  • Public Sector and Government Agencies

    Agencies publish forms, notices, reports, and FOI/FOIA responses primarily as PDFs. Automating PDF/UA tagging at the source ensures consistent accessibility, lowers complaint risk, and shortens publishing timelines. Tagged content also improves open-data usability by making tables and fields easier to extract at scale.

    U.S. federal agencies (and many state/local bodies) must conform to Section 508 (WCAG-based). In the EU and UK, the Web Accessibility Directive/EN 301 549 and the UK’s public-sector regulations set similar expectations, while EAA 2025 broadens coverage for services delivered to consumers. Across regions, PDF/UA provides the concrete standard for accessible PDF files.
