Compliant instead of taking risks

Avoid legal risks and potential complaints by consistently and automatically checking your PDFs for accessibility. axesPAC ensures that you stay on top of requirements such as WCAG and PDF/UA.

Proven technology: The PAC engine in axesPAC

The checks in axesPAC are based on the established PAC Engine, the technology behind the well-known PDF Accessibility Checker (PAC).

The PAC Engine reliably analyzes PDF documents for accessibility, identifies violations of relevant standards, and delivers structured results for direct further processing. With axesPAC, you can integrate this proven technology into your applications in a scalable manner via API.

You check PDFs, but you don't have a clear overview

Individual checks take time and resources
Quality depends on manual processes
There is a lack of transparency regarding all documents
Errors are often detected too late

Result: You don't know how accessible your documents are

axesPAC integrates checks directly into your systems

Every file is checked automatically
Results are available immediately
No manual follow-up work required
Fully integrable into existing workflows

Result: You get control instead of random checks
