PDFix SDK

The Enterprise Engine for Automated PDF Accessibility PDFix SDK is a high-performance, cross-platform development library designed to automate PDF accessibility (WCAG 2.1/2.2 & PDF/UA) and structured data extraction at scale. It allows developers to integrate professional-grade remediation directly into their own applications, converting millions of static PDFs into accessible, compliant, and machine-readable documents without manual intervention. The Primary Value: Removing the Manual Bottleneck For organizations managing massive document repositories, manual remediation is impossible. PDFix SDK solves this by providing a programmatic AI Layout Recognition engine. This engine automatically identifies document structures - headings, multi-column text, complex tables, and reading orders - ensuring your organization meets ADA Title II, Section 508, and EAA mandates through pure automation. Key Features & Functionality Automated Accessibility (Auto-Tagging) Programmatically generate semantic tag trees. The SDK identifies headings, lists, and tables to ensure screen-reader compatibility automatically. High-Volume Batch Processing Built for speed and stability, the SDK processes large-scale document sets in backend environments (Windows, Linux, macOS). Structured Data Extraction (JSON/XML/HTML) Convert PDF content into structured formats. It preserves the logical reading order and table relationships, making data available for external databases or web views. Integrated VeraPDF Validation Automate compliance testing. The SDK includes the industry-standard VeraPDF engine to validate documents against PDF/UA standards as part of your automated pipeline. Responsive HTML5 Derivation Automatically transform PDFs into Responsive HTML, allowing documents to be viewed seamlessly on mobile devices while maintaining full WCAG compliance. On-Premises Security The SDK runs entirely within your infrastructure. No data is ever uploaded to a third-party cloud, ensuring 100% privacy and compliance with GDPR, HIPAA, and FERPA. Why PDFix for Scale & Enterprise Document Accessibility? Large organizations face a compliance gap where manual tagging cannot keep up with the volume of generated content. PDFix is engineered specifically to close this gap: High-Velocity Processing: Process thousands of pages per minute. Layout Templates for Consistency: For repetitive documents like bank statements or invoices, PDFix uses rule-based Layout Templates. Security-First Architecture: Unlike cloud services, the SDK runs on-premises and automate accessibility without sensitive data ever leaving environment. Audit-Ready Compliance: Every automated workflow includes integrated VeraPDF validation, generating detailed logs and reports (JSON/XML) to prove compliance for legal audits.
