PDF/A Conversion Library: ISO-compliant PDF to PDF/A
Convert your PDF files and documents to PDF/A, the ISO standard for long-term archiving.
PDF/A files created with GdPicture.NET are ISO-compliant.
Converted files are fully searchable and keep a reasonable size thanks to the many compression techniques supported in GdPicture.NET.
The PDF SDK also includes a PDF/A validator.
The PDF/A standard
PDF/A is the electronic document file format for long-term preservation. Its purpose is to ensure that electronic documents can be viewed and reproduced exactly the same way in the future, no matter which software is used.
For this reason, the document must contain all necessary elements (fonts, color profiles, a digital signature if it is present in the original document) for an authentic reproduction, but it may not contain any references to external content or resources.
