FAQ

What does PAC cost?

PAC is completely free of charge for all types of applications.

Is PAC also approved for commercial applications and free of charge?

Yes, as long as you comply with point 7.2 of our General Terms.

Is there a Mac version of PAC?

No.
A Mac version is in the works (release not before 2026), but there is currently none.

Does PAC run under Citrix, Terminal Server and similar systems?

Yes.

Is there an installation file (*.msi)? How can I roll out PAC to many people?

We currently only provide PAC as a ZIP file, so there is no MSI.

You can download the ZIP file, unzip it into a folder and distribute this folder using the usual deployment tools (Active Directory etc.). However, it is essential that you observe point 7.2 of our General Terms.

The PDF/UA and WCAG checks show green checkmarks, but the quality checks do not ‒ is this relevant for me?

See our explanations on the quality checks.

Is the test result legally compliant and does it guarantee absolute accessibility?

The PDF Accessibility Checker PAC is the globally used tool for checking accessible PDF files and has been established since 2010. It supports both the DIN/ISO standard PDF/UA and the WCAG (Web Content Accessibility Guidelines). Not all requirements of both standards and guidelines can be checked automatically by software. Additional checks by a human are always required, for example to determine whether the semantic markup is appropriate. The test result can therefore not be legally binding, but it is an indicator. If all the check marks are green on the PDF/UA and WCAG tabs, this only means that all automatically checkable requirements have been met.
