View Full Version : Using Ghostscript to convert pdf to jpg

21st July 2006, 10:08 PM
Hi - I've need to convert a large pdf into lots of jpg images, and I understand that I need to use ghostscript to do this.

I need to be able to set the resolution of the images, and do the whole thing at the command line. Can anyone help with this?

FYI - I found one solution for png's (jpgs were very poor quality):

gs -dSAFER -dBATCH -dNOPAUSE -r150 -sDEVICE=png16m -dTextAlphaBits=4 -sOutputFile=page-%02d.png mydoc.pdf

Hi, i use the following command for my online PDF to JPG conversion site, which give you a very high quality JPG image:

gs -q -dQuiet -dSAFER -dBATCH -dNOPAUSE -dNOPROMT -dMaxBitmap=500000000 -dAlignToPixels=0 dGridFitTT=2 -sDEVICE=pngalpha -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r300x300 -dFirstPage=1 -dLastPage=[last-page-number] -sOutputFile=[output-file] -f[input-file]
