#PDF FILE MINIMIZER SOFTWARE#

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.

#PDF FILE MINIMIZER FOR MAC#

Note for mac users finding this post (or Linuxbrew users): there is a Homebrew install formula: brew install -HEAD pts/utils/pdfsizeopt (Note: I tend to use it after having first done a vectorization-OCR in Adobe Acrobat, which can have a dramatical size impact on some scanned text documents.)ĭownload and install the executable: curl -L -o Ĭp pdfsizeopt.single /usr/local/bin/pdfsizeopt degrading images to a point of unreadability), it might not be the tool you need, but as an always-working go-to solution, to reduce unnecessary big sizes in PDFs without loosing in readability, information and acceptable image quality, I think it is the best option. Now, if you need to attain a certain size whatever the consequences (inc. It is much more efficient in terms of size reduction than any of the previous CLI and GUI software that I have tried (including convert, gs, pdftk, etc.) - although possibly slower with pngout activated -, and does not have some of their issues (no heavily pixelated/degraded images, no loss of metadata such as table of contents, etc.). Depending on the document source, you might want to reduce the color depth ( -depth argument). I was able to achieve great compression ratios for scanned/photographed documents (depending on the settings).

#PDF FILE MINIMIZER 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.

#PDF FILE MINIMIZER PDF#

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.

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

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

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