PDF Accessibility Checker (PAC) 2.0
Check PDF documents for ISO Standard PDF/UA conformity
PAC 2.0 is the first PDF/UA validation tool in the world.
PAC 2.0 allows to check PDF documents for accessibility
incompliance with the ISO-Standard 14289-1:2012-07,
known as PDF/UA (Universal Accessibility).
PDF/UA ensures user experience at its best.
Only high quality accessible PDFs can be processed by
assistive technology* (AT) such that they can be read and
navigated by persons with disabilities.
0 error «only» represent technical accessibility.
The inspection catalog for PDF/UA conformity («The
Matterhorn Protocol») comprises 136 error conditions of
which 108 are clearly automatically testable. PAC 2.0 lets you
check them at a click.
PAC 2.0 supports you in the complementary manual checks.
Additional visual checks regarding semantics and logical
reading order are essential. For your assistance PAC 2.0
comes with a Preview and a detailed structural view.
* A Free AT for blind people is the screen reader NVDA, one for persons with
visual impairments is the VIP PDF-Reader.
