Greetings,
I would like to put pdfs of game manuals and other period-correct PDFs which I can read while using Acrobat Reader under Windows 3.11. However, most of the PDF files I have will not work, as they were made with modern versions of Adobe Acrobat. Is there a way, such as a site or an open source program which can convert PDFs to version 1.2?
ghostscript can do this with something like:
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.2 -dNOPAUSE -dBATCH -sOutputFile=output.pdf input.pdf
As Actobat 3.0 is quite slow to render, you can reduce the DPI by adding
-dPDFSETTINGS=/screen
as argument.

Thank you. I have been trying to do this after I downloaded the latest ghostscript program. However, I am getting Error: /undefined in -sDEVICE=pdfwrite
Which command are you using?

I am trying it how you posted it, though changing pdf name and location. I am completely new to the program.
Maybe add quotes to your filenames if there's a space?

Still getting errors. I must not be understanding the syntax or am somehow leaving something out or doing it wrong. I appreciate your efforts. I will have to study multiple examples of the program being used in various ways.
Or your build of Ghostscript doesn't have the PDF writer function included.

Hmm, perhaps. I downloaded the latest version from the site. Maybe I should install a previous version...
