How to convert from Scanned Searchable PDF to PDF/A-1a files?

I need to convert Scanned Searchable PDFs (produced with Tesseract or Abbyy) to PDF-A-1a.

I'd like to use your pdf2pdfa command line tool to do so.

I downloaded the trial from here:

https://www.verydoc.com/pdf2pdfa_cmd.zip

On below web page, it says that I can create PDF-A-1a with the tool but whatever I do, I always get PDF-A-1b output.

Dear,

Yes that is the point. I am looking for PDF-A-1a and not PDF-A-1b

I know it's only one letter but it's important.

Your web page:

States:

Supports both PDF/A-1a and PDF/A-1b.

I need the A-1a variant. Not the A-1b.
