Ghostscript is a powerful PostScript and PDF processing engine. With Ghostscript, it is possible to further edit and convert your PDF specifications to your desires.
We have integrated a Ghostscript command pipeline, that can convert your PDF file based on your provided arguments, before being downloaded or sent to Webhook integrations. You can provide your custom Ghostscript commands in our settings page
For example, let's say you would like the PDF to be converted from it's default PDF version 1.7 to PDF/X-3 version 1.3, you would provide the following argument: -dPDFX
Another example, if you would like to convert the PDF version to 1.4 and convert all colors including images in the PDF to CYMK, you would provide the following arguments:
Please note that each argument is separated by a single space
For more available arguments you can study Ghostscript Use .
Also note that we provide other default arguments such as (so you should not):
-sDEVICE=pdfwrite -sOutputFile=out-x3.pdf PDFX_def.ps input.ps
