It's powerful yet simple and extremely easy to use interface to combine various image formats & PDF into PDF in few clicks only. PDF Combiner is an application to combine thousands of PDF and Image files into one or more PDF document in minutes. Status=$(gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile='$' '$f' 2> /dev/null)Įxample output: processing inp1.pdf.

Just copy it in the folder with the PDFs and execute from there. The following Bash script merges all available PDFs in a folder one by one and gives a success status after each merge. I had the problem that a few PDF merges produced some error messages.Īs it is quite a lot trial and error to find the corrupt PDFs, I wrote a script for it. Here is a Bash script which checks for merging errors. UPDATE: first of all thanks for all your nice comments!! just a tip that may work for you guys, after googleing, I found a superb trick to shrink the size of PDFs, I reduced with it one PDF of 300 MB to just 15 MB with an acceptable resolution! and all of this with the good ghostscript, here it is: gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/default -dNOPAUSE -dQUIET -dBATCH -dDetectDuplicateImages -dCompressFonts=true -r150 -sOutputFile=output.pdf input.pdf In this way you wouldn't need to install anything else, just work with what you already have installed in your system (at least both come by default in my box). In both cases the ouput resolution is much higher and better than this way using convert: convert -density 300x300 -quality 100 mine1.pdf mine2.pdf merged.pdf Or even this way for an improved version for low resolution PDFs (thanks to Adriano for pointing this out): gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -sOutputFile=merged.pdf mine1.pdf mine2.pdf

Try the good ghostscript: gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=merged.pdf mine1.pdf mine2.pdf
