Thank you for using Syncfusion products,
Conformances can be added only to documents created from scratch. Currently, Essential PDF do not support converting PDF documents to PDF/A-1b or PDF/X-1a conformance documents. We have logged a feature request in our database, and we will let you know once we have implemented this feature.
Please let us know, if you need further assistance.

Searching throught syncfusion I found this link teaching how to importing pages from an existing document...
I added a conformance to the new document and apparently it works!
'Load the PDF document.DimloadedDocumentAsNewPdfLoadedDocument("Input.pdf")'Create a new PDF document.DimdocumentAsNewPdfDocument(PdfConformanceLevel.Pdf_A1B)DimstartIndexAsInteger=0DimendIndexAsInteger=loadedDocument.Pages.Count-1'Import all the pages to the new PDF document.document.ImportPageRange(loadedDocument,startIndex,endIndex)'Save the document.document.Save("Output.pdf")'Close both document instances.loadedDocument.Close(True)document.Close(True)

We are glad to know that you have found the solution, but this solution will not make the PDF fully A-1b compliant, the conformance may get fail when you check with Adobe Preflight if the existing document has transparent text and non-embedded fonts, because Pdf/A - 1b conformance files must follow the certain rules including color management guidelines and using embedded fonts for rendering. While importing PDF to PDF/A - 1b those rules are not get preserve, so that we are not suggested this solution to you. As we said earlier we have logged the feature request to this in our database, we will let you know once it has been implemented.
Please let us know if you need further assistance.

Greetings from Syncfusion.
We have provided support for converting an existing PDF in to PDF/A-1b conformance document. More details about the same can be found in the below UG documentation link:
