Everything You Need to Achieve and Maintain PDF Compliance
From AI-powered automated remediation to manual post-processing tools and a full compliance dashboard — PureData gives your team complete control over accessibility at scale.
Upload one PDF or a full S3 bucket. The engine processes every document in parallel using AWS Lambda — no queue waiting, no per-file bottlenecks.
AI detects and applies WCAG-required PDF tags: Document, Sect, P, H1–H6, Table, Figure, List — with correct nesting and tag hierarchy for screen readers.
Computer vision models describe charts, diagrams, and images in context-aware language — not generic placeholders. Reviewable before final output.
All processing runs within your VPC. Documents never leave your AWS account. Data sovereignty maintained for FERPA, HIPAA, and government compliance.
Multi-column layouts, sidebars, callout boxes, and footnotes are correctly sequenced so screen readers navigate content in the intended reading flow.
Complex merged-cell tables are tagged with TH scope attributes, summary attributes, and header-ID associations per WCAG 2.1 Success Criterion 1.3.1.
Document-level and passage-level language tags applied automatically. Title, author, and subject metadata injected to meet PDF/UA clause 7.1 requirements.
Track remediation status, WCAG pass/fail rates, and pending review items across your entire document library from a single dashboard.
Per-document AWS cost breakdown and Adobe API usage metrics — so your finance team has the data to forecast accessibility operations budget.
Search by filename, filter by uploader email, role, date range, and compliance status. Combine filters for instant scoped reporting.
AI-generated alt text is surfaced for human review on complex images, charts, and decorative elements — with one-click accept or inline editing before publishing.
Add, label, and validate interactive PDF form fields post-processing. Ensures ARIA-equivalent labeling for screen reader navigation of fillable forms.
Every manual edit is logged with timestamp, user, and change type — producing a defensible compliance record for audits, procurement, and legal proceedings.

- WCAG 2.1 AA output
- Compliance Standards
Every Standard Your Organization is Legally Required to Meet
Web Content Accessibility Guidelines — the international baseline required by ADA, Section 508, and EN 301 549.
Mandatory for federal agencies and contractors. Revised 508 standards align to WCAG 2.0 AA with additional electronic document requirements.
Courts have ruled that digital documents constitute places of public accommodation. Non-compliant PDFs expose organizations to private lawsuits.
The international standard for universally accessible PDF files. Required for government procurement in multiple jurisdictions.

- Who We Serve
Built for Every Organization With a Document Accessibility Obligation
Meet OCR regulations, NPRM 2024 compliance deadlines, and Title II ADA requirements for institutional documents. Protect your accreditation status and avoid Department of Education enforcement actions.
Avg. university document library: 25,000–200,000 PDFs
Serve patrons with visual impairments, dyslexia, and cognitive disabilities through fully accessible digital collections. Meet state library agency compliance mandates and ALA accessibility commitments.
Section 508 required for all federally-funded library systems
Mandatory Section 508 compliance for all electronic documents published or distributed by federal agencies. Avoid DOJ enforcement investigations and Civil Rights Division findings.
Section 508 non-compliance exposes agencies to formal complaints
Accessible patient-facing PDFs satisfy ADA Section 504 obligations for healthcare recipients. Protect HIPAA-compliant workflows with AWS-native processing that never routes PHI to third-party servers.
HIPAA-safe: all processing stays within your AWS VPC
- Frequently Asked Questions
Technical and compliance questions, answered
The engine addresses all document-applicable Level AA success criteria including: 1.1.1 (non-text content / alt text), 1.3.1 (info and relationships / structural tagging), 1.3.2 (meaningful sequence / reading order), 1.3.3 (sensory characteristics), 2.4.2 (page titled), 3.1.1 (language of page), and 4.1.2 (name, role, value for form elements). Complex criteria requiring human judgment — such as 2.4.6 headings and labels adequacy — are flagged for manual review.
Yes. AWS Textract performs OCR on scanned documents before remediation, extracting the text layer required for structural tagging. For heavily degraded scans, OCR confidence scores are surfaced in the review queue so operators can manually verify extraction quality before the document is published as accessible.
All processing occurs exclusively within your own AWS account and VPC. Documents are stored in S3 buckets you own and control, with server-side encryption (AES-256) enforced by bucket policy. Lambda functions process documents ephemerally — no document content is retained in function memory after processing completes. CloudTrail records every API call for audit purposes. For regulated industries, we support HIPAA Business Associate Agreements through AWS native controls.
Adobe Acrobat Services API is the industry-standard PDF manipulation engine used to apply WCAG-compliant structural tags, reading order, and metadata to processed documents. Adobe API costs are passed through at standard Adobe pricing — typically $0.05–$0.10 per document at volume. Your admin dashboard shows real-time API call consumption so you can forecast monthly Adobe costs alongside your AWS infrastructure spend.
Yes. The platform exposes a REST API that accepts document upload requests and returns compliant PDF download URLs. S3 event triggers allow documents deposited into a designated S3 prefix to be automatically queued for processing — enabling no-code integration with SharePoint, Drupal, WordPress, Hyland OnBase, and other document management systems that support S3 or webhook callbacks.
PureData Cloud produces WCAG 2.1 AA compliant output and generates a documented, timestamped remediation audit trail — both of which are foundational to a defensible accessibility program. We always recommend pairing automated remediation with a periodic human audit and legal review. Automated tools address the majority of technical accessibility barriers, but demonstrating good-faith, ongoing compliance efforts is also a significant factor in ADA litigation outcomes.
