Convert an existing PDF file to PDF/A-1b which is incompatible with the standard

Do you know how to force a conversion of an existing PDF file that is incompatible with archiving standards in PDF/A-b format without altering the content?

There is the option to convert it to TIFF beforehand, but do you have any other options?



As per our understandings, you want to convert an existing invalid PDF/A file to valid PDF/A document? Can you please confirm and share the sample file with us so that we can test the scenario in our environment and address it accordingly.

Exactly. Here is the situation: we have a web service that receives PDF files from outside and we systematically convert them to PDF/A. Among the files received, there are some that are not compatible with PDF/A format, but we still must convert them to this format and we may lose text or layout.

An example would be a file containing special fonts that are not embedded or a file that was created by another application and contains complex graphic. In short, several situations can be encountered.


Could you please share sample PDF document for our reference? We will test the scenario in our environment and address it accordingly.

Here is an example file. Some files remain unchanged after conversion, but others lose their layout or the font is not substituted.
