title: PDF to PDF/A conversion
body: <p>I receive many files in PDF format. They come as email attachments. I must supply them to an intranet software. I have written a VB.NET application that reads those emails, collect their text and attachments and fill the form from the intranet software accordingly.</p>
  
  <p>My problem is: the new version of intranet software requires PDF/A compliance. I'm aware of websites that do this conversion, but I wanted to know if there is some executable, library or package that I could include freely in my project to perform this locally in a simpler fashion than robot-browsing another website.</p>
  
  <p>Thank you very much!</p>
