This release includes new PDF/UA-1 (Matterhorn machine) validation, as well as fixes and enhancements of the PDF parser. Thank you to the community for testing the release candidate, an additional fix to the URL validation in XMP metadata has been added in the final release.
veraPDF is the first open source PDF/A validator, covering all parts of the PDF/A standards. Originally funded by the PREFORMA project, veraPDF has been sustained and maintained by the Open Preservation Foundation since 2017. 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.
Our thanks go to all contributors, particularly the Dual Lab development team, and the OPF Product Board.
veraPDF is open source, so it is free to download, use and modify. However, there are costs to host, maintain, and develop it. If you use veraPDF, please consider supporting its development by becoming an OPF member or making a donation.
