Command-line tools for PDF processing
A collection of command line solutions for different PDF‑manipulation use‑cases, such as:
- PDF splitting (“explode” one multi‑page PDF into set of single‑page PDFs)
- cropping PDF pages
- …
General: Overview of PDF-processing and manipulation tools
MuPDF (mutool)
- Download: no binary, install via
sudo port install mupdf - Changelog: https://mupdf.com/releases/history
PDFtk server (pdftk)
Coherent PDF (cpdf)
- Download: https://www.coherentpdf.com/eval.html (fully functional demo)
pdfcpu
- Download: https://github.com/pdfcpu/pdfcpu
- Changelog: https://pdfcpu.io/changelog.html
Other (non-tested) tools

Case #000: Minimize PDF size
Example use‑case: Obvious.
cpdf
cpdf -squeeze "src.pdf" [-squeeze-no-recompress] -o "dst.pdf"
pdfcpu
pdfcpu optimize "src.pdf" "dst.pdf"
Case #001: Split each page of PDF into several pages (posterisation)
Example use‑case: you have (scanned) pages where each PDF page contains two physical pages, and want to crop those into two.
MuPDF (mutool)
mutool poster -x 2 "src.pdf" "dst.pdf"
Coherent PDF (cpdf)
cpdf -chop "1 2" "src.pdf" -o "dst.pdf"
Indirect way: Duplicate each page, then crop out left or right half on odd and even pages
pdftk shuffle && cpdf -mediabox:
pdftk A=src.pdf shuffle A A output dst.pdf cpdf -mediabox "0mm 0mm a5landscape" "src.pdf" odd -o "srcOdd.pdf" cpdf -mediabox "148.5mm 0mm a5landscape" "srcOdd.pdf" even -o "dst.pdf"
The second step might also be done in Adobe Acrobat “Crop pages” function.
Case #002: Crop pages of PDF
See MuPDF documentation on different PDF page boxes (media|crop|art|trim|bleed]box).
Coherent PDF (cpdf)
cpdf -mediabox (/cropbox/artbox/trimbox/bleedbox):
cpdf -mediabox "0mm 0mm a4portrait" "srcA3.pdf" -o "dstA4.pdf"
Adobe Acrobat
Note that Acrobat won't let you crop MediaBox.
- Go to “Edit PDF” and then “Crop pages” function.
Case #003: Remove cropped content from PDF
Example use‑case: You have cropped some pages but you want to actually remove the content, since otherwise it is only hidden but remains in PDF – this can be seen when you inspect the PDF in Adobe Acrobat via “Edit PDF” and zoom out the page – the cropped content will be selectable, although not visible, since it is out of the page margins.
mutool trim ‑o “derotateSplit trim.pdf” ‑b cropbox “derotateSplit.pdf”
MuPDF (mutool)
mutool trim -o "dst.pdf" -b cropbox "src.pdf"
Adobe Acrobat
- Download custom user script CropBoxFix
- Import it into Acrobat Preflight (by double‑clicking)
- Run preflight and the script
