PDF/UA Validation & Conversion Tools
A complete toolkit for document accessibility, e-invoicing compliance, and team collaboration.
Online PDF Accessibility Checker
Upload any PDF and get an instant compliance report. Our validator checks against PDF/UA (ISO 14289) and flags missing tags, reading order issues, and alt text problems. Unlike PAC, it works in your browser — on Mac, Windows, and Linux. Free PDF accessibility check — no account required for your first scan.
Accessible PDF Conversion
Convert your existing documents into fully tagged, PDF/UA-compliant files. Our engine adds proper heading structure, reading order, alternative text placeholders, and metadata — turning inaccessible PDFs into documents that meet WCAG 2.1 AA requirements.
ZUGFeRD & Factur-X Invoices
Generate hybrid PDF invoices that embed structured XML data following the ZUGFeRD 2.1 / Factur-X standard. Your invoices are human-readable and machine-processable at the same time — ready for automated bookkeeping and EU-wide e-invoicing compliance.
XRechnung for Public Sector
Create XRechnung-compliant electronic invoices required by German federal, state, and municipal authorities. PDF UA Kit generates valid EN 16931 data in the UBL or CII format mandated by the E-Rechnungsverordnung — no manual XML editing required.
XBestellung (Electronic Orders)
Support the full procurement cycle with XBestellung-compliant electronic purchase orders. Generate and process structured order documents that integrate seamlessly with German public-sector ordering workflows and existing ERP systems.
EAA & BFSG Compliance
Stay ahead of the European Accessibility Act (EAA) and the German Barrierefreiheitsstärkungsgesetz (BFSG) taking effect in June 2025. PDF UA Kit ensures your documents meet the accessibility standards required by law — protecting your organization from penalties and making your content available to everyone.
API Access
Integrate PDF/UA validation and conversion directly into your workflow with our RESTful API. Automate document processing, batch-validate files, and generate accessible PDFs programmatically — perfect for high-volume document pipelines.
Team Management
Invite team members, assign roles, and manage permissions across your organization. Track document processing usage per team, share templates, and maintain a centralized audit trail of all accessibility checks.
