AI saves 90% of work, delivers 100% accessibility

Fast, accurate, and inclusive

Accessible PDFs don’t have to be complicated:
Our AI recognizes content, creates accurate descriptions, and ensures the correct structure.

This automatically turns every document into accessible HTML and a standards-compliant PDF/UA.

The result: your content becomes readable for everyone—quickly, easily, and reliably.

Workflow

How PDF Pro works

A compact one-line overview — from step 3 the path branches, depending on whether your PDF already has tags.

01 Your PDF: select and upload

02 PDF Pro: identifies status and page count

03 If already tagged: structure is repaired directly on the original

04 Otherwise: AI creates structured HTML

05 Both paths: image descriptions, tables, alt text and reading order added automatically

06 HTML path only: upload as a PDF/UA text version

07 Result: repaired original or newly merged hybrid PDF — both PDF/UA and PDF/A-2a compliant

08 Documentation: accessibility verification

Core areas

PDF Pro brings structure, review and delivery together

The homepage now focuses on what PDF Pro does today: build a reliable, PDF/UA- and PDF/A-2a-compliant structure, handle charts and tables cleanly, and improve already-tagged documents without rebuilding them from scratch. The AI-based image analysis runs once and feeds both paths equally.

Structure and tags

PDF/UA-compliant tag structure
Headings, lists and captions
Tables with header cells and cell mapping
Bookmarks, language and artifacts
HTML alternative version

Graphics and layouts

Images with real alt text
Charts with data tables as fallback
Complex multi-column layouts
Reading order and visual logic
Checks for common document patterns

Existing PDFs

Existing structure stays intact
Missing elements are filled in
Images get the same AI-generated descriptions as on the HTML path
Useful for already tagged PDFs
Targeted improvement instead of rebuilds
Reviewable output for delivery

Quality and review

Technical validation plus plausibility

PDF Pro checks more than formal PDF/UA compliance. We also look at whether the accessible output matches the visible document: reading order, tables, images, links and complex layouts.

Reading order

Multi-column pages and sequences are checked for plausibility.

Tables

Header cells, scope and mapping are considered deliberately.

Images and charts

Alt text and chart fallbacks are checked for practical use.

Validation

Validated with veraPDF, PAC and Acrobat as pragmatic checks.

The layout stays visually intact. For particularly complex or sensitive documents, an additional manual final review is advisable.

Sensitive projects

For sensitive and complex documents

Public documents can start right away. For internal, sensitive or heavily regulated collections, we design the processing path more deliberately.

Privacy-aware processing

For customers with strict privacy requirements, private or isolated operating models are available.

Local or dedicated operation
Private infrastructure instead of standard cloud
Aligned review and release steps

Enterprise and large volumes

For large document sets, custom integrations and recurring workflows, we build the process around your environment.

Bulk processing
