NAME

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

SYNOPSIS

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.

The following options are available:

-g

Enable grayscale conversion which can further reduce output size.

-h

Show help screen.

-o outfile

Output file, default is standard output.

-r res

Resolution in DPI, default is 72.

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:

Reduce PDF resolution to 300 dpi:

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