Basically I have a pdf letters generated in a various of formats like A4, A3 and
customers would like to convert those formats into Letter format

All pdfs are created using pdfmake library in node.js environment and I need to
convert all of this documents into specified format.
I don’t want to write a new layouts for each of those pdfs according to the
Letter format because it will take too much time and I willing to make it easier

For conversion I am using this command
pdfjam --outfile out.pdf --paper letter input.pdf

But I have a problem with one case of convertion, for instance
If I insert images into pdf and provide a link to this image after convertion link for the
image is disappears

Here is the demo of pdf document layout defined using pdfmake.
Codesandbox

And after convertion to letter format that link for the image is gone.
If you know how to fix this or any other way for conversion I will be happy to use it 🙂
