PDF Usability Checker (PUC)
Produced by DocAxess
PDF Usability Checker (PUC) is a free online tool developed by DocAxess to help users quickly evaluate the accessibility tagging quality of PDF documents.
PUC provides a structural analysis of key accessibility elements — such as headings, paragraphs, lists, tables, and images — in accordance with the PDF/UA standard. While it does not guarantee full compliance or perform remediation, PUC enables non-specialists and content creators to conduct early-stage diagnostics before expert review.
The tool requires no installation and is designed to be user-friendly and accessible. It is especially useful for awareness-raising, internal testing workflows, or training contexts.
