This software is supplied under the GNU AGPLv3 and comes with NO WARRANTY: Sample output: $ time gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dNOPAUSE -dBATCH -sOutputFile=out.pdf in.pdfĬopyright (C) 2019 Artifex Software, Inc. You can also add time in front of the command to see how long it takes (this works with any Linux command). Gs -sDEVICE=pdfwrite -dPDFSETTINGS=/screen -dNOPAUSE -dBATCH \ High compression: 72 dpi (small file size-may produce grainy or unreadable results in some cases, so try it and give it a shot).Gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dNOPAUSE -dBATCH \ Medium compression (recommended): 150 dpi (medium file size).Gs -sDEVICE=pdfwrite -dPDFSETTINGS=/printer -dNOPAUSE -dBATCH \ Low compression: 300 dpi (large file size).Note: you may also add -dQUIET to suppress all output to stdout. Use Ghostscript ( gs) to compress input.pdf into output.pdf 2020), and there's no need to override those values. Note that I've removed the -dCompatibilityLevel=1.4 part of the command used in some other answers here (including the most-upvoted answer) because this table indicates that 1.5 or 1.7 are automatically used for this setting today (27 Dec. Referencing this answer and this answer, and after trying a bunch of the answers here, and doing a bunch of research and experimenting, I've come up with the following. Depending on the document source, you might want to reduce the color depth ( -depth argument).įor my other, pdfsizeopt-based answer, see here. I was able to achieve great compression ratios for scanned/photographed documents (depending on the settings).
#Super resize pdf zip#
You have the choice between BZip, Fax, Group4, JPEG, JPEG2000, Lossless, LZW, RLE or Zip as alternate compression methods (some only allow b/w images). jpeg compression might not be the best choice due to compression artifacts. For jpg it is between 1 to 100 with 100 the best quality, but lowest compression Higher pixel densities increase quality and size -density: the pixel density in dpi (e.g.

If you have a pdf with scanned images, you can use convert (ImageMagick) to create a pdf with jpeg compression (You can use this method on any pdf, but you'll loose all text informations).įor example: convert -density 200x200 -quality 60 -compress jpeg input.pdf output.pdf The exact settings for each of these, including their DPI values, are shown in the dozens of options in this table. /default selects output intended to be useful across a wide variety of uses, possibly at the expense of a larger output file./prepress selects output similar to Acrobat Distiller "Prepress Optimized" (up to version X) setting./printer selects output similar to the Acrobat Distiller "Print Optimized" (up to version X) setting.
Presets the "distiller parameters" to one of four predefined settings: Reference: : Controls and features specific to PostScript and PDF input
