What is a PDF/A compliant document?

Some PDF documents are more safe to sign than others. For most use cases, regular PDF documents will be ok. For other cases or document types, such as contracts, we recommend the use of PDF/A documents, specifically at least PDF/A-1b (basic conformance). Simply put, a document that is PDF/A compliant includes all resources so that the way the document looks will not change due to external resources. For example, an external font might be used which causes text in the document to become larger or smaller, obfuscating or revealing other parts of the document that might be relevant. For example, this could make a leading 1 in a number to not be visible on first review. In some cases you will see a warning using our services, along the lines of “Please check this document carefully, as you are about to sign a non PDF/A compliant document, which means that the appearance of the document can be changed”.
