 Note that adjusting page sizes by cropping mediabox is (to my knowledge) the only way to do it without altering the PDF content in any way (as explained [[https://www.coherentpdf.com/cpdfmanual/cpdfmanualch3.html#x7-570003.6|here in Coherent PDF manual]]). Cropping other boxes might lead to PDF structure being changed.
+Additionally, if you want to "reset" the coordinate system after cropping pages so that the pages start at (0,0), you might use the ''-upright'' command, which "makes sure the media box has its origin at (0,0), changing other boxes to compensate" (see cpdf manual section [[https://www.coherentpdf.com/cpdfmanual/cpdfmanualch3.html#dx6-56001|3.4 Rotating Pages]]):

+cpdf -upright "src.pdf" -o "dst.pdf"
