PDF Cropping

20200717 To crop a pdf document (multiple pages included) use pdfcrop with –margins. For example to remove crop marks from a book proof in each of the four corners of the document, experimentation might suggest a crop margin of -50 works.

  $ pdfcrop --margins -50 input.pdf output.pdf
  $ evince output.pdf
