Automatic PDF testing: Ensuring accessibility with CAAT & PAC
A bad feeling about PDFs on your website?
Your website contains countless PDFs. No one knows exactly how many there are. And whether these documents are truly accessible remains unclear.
Checking them one by one with PAC takes an enormous amount of time, is error-prone, and hardly feasible in practice.

CAAT brings clarity
- Automatic search: CAAT scans your entire website and finds every single PDF.
- Central overview: All files appear in a clear list with key data.
- Accessibility check (PDF/UA): Each document is automatically tested with PAC (powered by axesSense), the recognized tool for PDF/UA compliance.
- Direct results: You immediately see which PDFs meet the machine-testable PDF/UA criteria and where action is needed.

Audit your entire website in no time – with no manual effort.
