I'm puzzled as to what program they used to compress the PDF file with such a good quality output (PDF format as well). This is the link I use to compress the file: https://online2pdf.com/pdf-reduce-size I've tried: gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dDownsampleColorImages=true -dColorImageResolution=150 -dNOPAUSE -dBATCH -sOutputFile=5.pdf COVERAGE_July-1-2016.pdf gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=5.pdf COVERAGE_July-1-2016.pdf convert -density 200x200 -quality 60 -compress jpeg COVERAGE_July-1-2016.pdf 5.pdf gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen -dNOPAUSE -dQUIET -dBATCH -sOutputFile=5.pdf COVERAGE_July-1-2016.pdf The last one above gave me decent size I think about 5MB but the quality wasn't very good. All others, size was hardly reduced or quality was terrible. Gimp will open only one page at at time, so it is not suitable for this conversion. -- Thelma
