Compress with Ghostscript

ghostscript command can be used to compress PDF files. It has multiple predefined settings:

-dPDFSETTINGS=configuration

Presets the "distiller parameters" to one of four predefined settings:

/screen selects low-resolution output similar to the Acrobat Distiller (up to version X) "Screen Optimized" setting.

/ebook selects medium-resolution output similar to the Acrobat Distiller (up to version X) "eBook" setting.

/printer selects output similar to the Acrobat Distiller "Print Optimized" (up to version X) setting.

/prepress selects output similar to Acrobat Distiller "Prepress Optimized" (up to version X) setting.

/default selects output intended to be useful across a wide variety of uses, possibly at the expense of a larger output file.

More information about these profiles can be found from https://www.ghostscript.com/doc/current/VectorDevices.htm#distillerparams
