I found a useful PDF shrinking script at http://www.alfredklomp.com/programming/shrinkpdf/. Unfortunately it was a bash script, and I could not use it in its current state, so I created a batch file version of it.
Not only did I convert it, I upgraded it. In addition to shrinking the PDF, you can drag and drop multiple PDFs onto the BAT file and they will be shrunk and placed in a new sub-directory.
The script requires Ghostscript which can be found here, http://www.ghostscript.com/download/. You may need to change the path to the Ghostscript executable on your computer.
</pre> @echo off REM Shrinks PDFs and puts them in a subdirectory of the first file REM Usage: shrinkpdf.bat file1 file2 ... REM Location of the Ghostscript exectuble set GSPATH="C:\Program Files (x86)\GPLGS\gswin32c.exe" REM Name of the subdirectory to store the shrunk files to set OUTSUBDIR=shrunk if "%~1"=="" ( echo Usage: shrinkpdf.bat file1 file2 ... goto end ) REM Take the path of the first file and use it as the folder REM to create the shrunk directory under set OUTDIR=%~dp1\%OUTSUBDIR% REM Create the output folder if it doesn't exist if not exist "%OUTDIR%" mkdir "%OUTDIR%" :shrinkPDF set OUTNAME=%OUTDIR%\%~nx1 @echo "Processing %~nx1" REM Work the shrinking magic REM Based on http://www.alfredklomp.com/programming/shrinkpdf/ %GSPATH% -q -dNOPAUSE -dBATCH -dSAFER ^ -sDEVICE=pdfwrite ^ -dCompatibilityLevel=1.3 ^ -dPDFSETTINGS=/screen ^ -dEmbedAllFonts=true ^ -dSubsetFonts=true ^ -dColorImageDownsampleType=/Bicubic ^ -dColorImageResolution=72 ^ -dGrayImageDownsampleType=/Bicubic ^ -dGrayImageResolution=72 ^ -dMonoImageDownsampleType=/Bicubic ^ -dMonoImageResolution=72 ^ -sOutputFile="%OUTNAME%" ^ "%~1" REM Load the next file shift REM Are there any more files to shrink? if "%~1"=="" goto end goto shrinkPDF :end <pre>

Thanks for posting this code. I am getting the following recurrent error when trying to compress a file –
Subsample filter does not support non-integer downsample factor
Failed to initialise downsample filter, downsampling aborted.
The only Downsample filter for monochrome images is Subsample, ignoring request.
I have set the path correctly to the executable gswin32c.exe and saved it in a bat file to execute.
I am not running into any helpful links on querying through error. Any help would be much appreciated.
It sounds like you are correctly pointed to gswin32c. Maybe your version of gswin32c is newer.
This page has the description of gs2pdf executable, http://www.ghostscript.com/doc/current/Ps2pdf.htm.
Maybe remove the line “-dMonoImageDownsampleType=/Bicubic ^” or change “/Bicubic” in that line to “/Subsample.” It looks like 1.5 is the default downsample value, so you might add a line
This is very nice, and it works fine!
I use GS 9.19 64 Bit
I installed GS 9.21 64 and downloaded the script as a ANSI format .bat file. I changed the location to the gswin64c.exe file correctly, and when I try dragging a pdf file onto the bat file, the cmd prompt just flashes and goes away without doing anything. Can you help?
I would suggest that you either try running it from the command prompt to set what it’s response or append “pause” to the end of the bat file and see what it says after.ypu run it again. The pause command will require you to press a key before closing the window.
Let me know what the error is.
Fantastic what you have done. I tried your script and it worked perfectly like 10 times and then for some reason everytime I try to use it the way I had always used it I get “Last OS error: No such file or directory. GPL Ghostscript 9.52: Unrecoverable error, exit code 1”. Do you know what might be causing this?
Thanks in advance!
I am sorry, but I do not know.
it’s work perfectly.
