Convert PDF file to PDF/A or PDF V1.6/V1.7 => in Acrobat Reader by JavaScript => at all costs

[Sergey27658849ko1q]

Respected Adobe Acrobat Universe, I send you all my warm greeting and profound respect.
Allow me to describe a simple problem I'm looking for the solution to:
"Convert PDF_file to PDF/A or PDF V1.6/V1.7 => in Acrobat Reader by JavaScript => at all Costs".

In fact I would have to create a Form.PDF with fillable fields to send it to customers. Customers only have Acrobat Reader. In the Form I have to implement the "[SAVE PDF-A]" button which saves (converts) the Form (with the fields filled in by customers) in PDF/A, or, PDF V1.6/V1.7 format.

I am aware that in Acrobat Reader, the Print => Adobe PDF / Microsoft Print to PDF function leads to the required result. and this is fine. However, if the client does not have Adobe PDF / Microsoft Print to PDF, I should implement a javascript embedet code in the button, which transfers the Form to file.PDF without javascript = uneditable = version 1.6 (acrobat 7.x)

To be more concise and make it easier for you to understand the problem, I attach the screenshots with 4 four steps:
1) Server Side: creates the Form for the customer
2) Client Side: the customer fills out the form using JavaSript Embeded
3) Client Side: Client saves(CONVERTS) the Form successfully using Adobe PDF / Microsoft Print to PDF
4) Server Side: I am forced to implement the same functionality with the help of JavaScript, in case, when the Client does not have the Adobe PDF / Microsoft Print to PDF settings.

I hope that this classic question, asked by numerous developers in Adobe Acrobat, already has sufficient answers to put an end to the problem.
Thank you again and wish you good work with Acrobat.
Best regards.

Thanks again.

Acrobat Reader can't convert PDF files to PDF/A.

Bernd is correct, you cannot do this client side with Reader. A better solution is for the client to submit the form to a server script that does the conversion. There are online REST services for converting to PDF/A. I think this can be done for free.
