Reducing the size of a PDF to 90 DPI ?
 
Hello,

I have a bit PDF of 30-35 MB, and I would like to reprint it to 90 DPI. Would you have a bash command?

regards
thank you

I don't have a bash command for that but I have used this site to compress pdf few times: https://www.pdfcompress.com/

Using ghostscript, you could take

Code:
$ gs -dBATCH -dSAFER -dNOPAUSE -q -sDEVICE=pdfwrite\
  -dCompatibilityLevel=1.3 -sPAPERSIZE=a4 -dPDFSETTINGS=/screen\
  -sOutputFile=output.pdf input.pdf
as a starting point. The option /screen stands for a low resolution. Other options are /printer, /prepress and /ebook.

what is the content of the pdf?
all text
or a mix of text and jpg's ( svg's will reduce better )

if text 90 dpi will be hard to read if printed
