You can combine resizing and conversion using convert -quality 25 -resize 50% *.jpg -adjoin output.pdf You could resize and lower the quality of the images using mogrify -resize 50% -quality 25 You can avoid the segmentation fault bug and do the compression at the same time if you use convert *.JPG -compress Zip output.pdfīut the zip compression appears quite inefficient and results in huge file sizes. jpg's (or format of your choice) in a folder and convert them to a single PDF - you can name it whatever you like.
