veraPDF 1.16 release candidate out now

The Open Preservation Foundation is pleased to announce that the first veraPDF 1.16 release candidate is now available for community testing. Download the release candidate here.

veraPDF is an open source, industry supported PDF/A validator, and part of the OPF reference toolset.

This release includes new features and fixes including: 

  • Added support for Function objects in PDF
  • Added detection and validation of the XMP encoding
  • Extended veraPDF model to include structure tree
  • More robust PDF parsing in case of critical low-level syntax errors
  • Optimized memory usage for more efficient batch processing with a large number of validation errors
  • GUI application improvements

We are also working towards PDF/UA validation, with added support for tagging structure of PDF. Read the draft release notes for more information.


Join us today at 16:00 CET for our ‘What’s new in veraPDF 1.16’ webinar to find out more.

Feedback welcome

We invite the community to download and test the release candidate. If you think you find a bug, please report it on the veraPDF issue tracker on GitHub or contact us with any feedback.

We will also continue internal testing of the release candidate and there may be a few small changes before the public production release.


Our thanks go to all the contributors, particularly the Dual Lab Development Team and the OPF Product Board for their ongoing input and feedback.

About veraPDF

veraPDF is the first complete open source PDF/A validator, covering all parts of the PDF/A standards. Funding from the PREFORMA project ended in 2017 and veraPDF is now sustained and maintained by the Open Preservation Foundation. Dual Lab provides active user support and carries out maintenance and bug fixes. The PDF Association’s PDF Validation Technical Working Group continues in its role resolving ambiguities arising from veraPDF’s usage in the field, and promoting adoption of PDF/A and veraPDF by developers worldwide.

veraPDF is open source, free to download, to use and to modify. However, it is not free to host, maintain, support or develop. veraPDF is a widely-used digital preservation tool, but currently, only OPF members support veraPDF financially as part of their membership fees. If you use veraPDF, please consider supporting its development by becoming an OPF member or making a donation towards development.
