veraPDF-shadow

Latest release: 1.16 (May, 2020)

veraPDF is the first complete open source PDF/A validator, covering all parts of the PDF/A standards. It comprises four components:

  • An implementation checker, which validates all parts and conformance levels of the PDF/A specifications
  • A policy checker, which allows users to implement additional custom checks to enforce institutional policy beyond the PDF/A specifications
  • A reporter, which processes the results, producing both human-readable and machine-parsable reports
  • A metadata fixer, which repairs metadata in files based on conformance with the standard

The software is accompanied by a comprehensive, atomic test corpus, covering each clause in the PDF/A specifications.

VeraPDF is implemented as a Java application and is usable on any Unix, Windows, or OS X platform with appropriate Java installation

veraPDF was originally developed with funding from the PREFORMA project (2014-2017). In 2018, it was a finalist for the Digital Preservation Awards 2018 in the Software Sustainability Institute’s Award for Research and Innovation.
