NAME

shrinkpdf —

A simple wrapper around Ghostscript to reduce the file size of PDFs

SYNOPSIS

shrinkpdf infile [outfile] [resolution_in_dpi]

DESCRIPTION

Inspired by some code found in an OpenOffice Python script, shrinkpdf feeds a PDF through Ghostscript, which performs lossy recompression by such methods as downsampling the images to a lower resolution. The result should be (but not always is) a much smaller file.

If invoked without [outfile], the shrunk file is written to standard output. If invoked without [resolution_in_dpi], a default resolution of 72 dpi is used.

If both [infile] and [outfile] are regular files, the script checks if the shrunk output file is actually smaller than the input file. If it is not, it writes a message to stderr and copies the input to output.

EXAMPLES

Reduce PDF resolution to 72 dpi:

$ shrinkpdf myfile.pdf
  >myfile-72dpi.pdf

Reduce PDF resolution to 300 dpi:

$ shrinkpdf myfile.pdf - 300
  >myfile-300dpi.pdf

Reduce PDF resolution to 150 dpi, specify [outfile]:

$ shrinkpdf myfile.pdf
  myfile-150dpi.pdf 150
