Extract Pages

Extract Pages

Export selected pages as single-page PDFs.

Command line

pdfcpu2 extract -m page in.pdf outDir             # every page
pdfcpu2 extract -m page -p 3 in.pdf outDir        # page 3 -> in_3.pdf
pdfcpu2 extract -m page -p 3 in.pdf -             # page 3 to STDOUT (needs exactly one page)

The stdout form makes it pipe-friendly:

aws s3 cp s3://bucket/contract.pdf - \
  | pdfcpu2 extract -m page -p 3 - - \
  | aws s3 cp - s3://bucket/pages/contract-page-3.pdf
