or 1200 DPI: mkdir -p images & pdftoppm -jpeg -r 1200 mypdf.pdf images/pg If you need more resolution, you can try 600 DPI: mkdir -p images & pdftoppm -jpeg -r 600 mypdf.pdf images/pg jpg format at highest quality (least compression) and still at 300 DPI: mkdir -p images & pdftoppm -jpeg -jpegopt quality=100 -r 300 mypdf.pdf images/pg
jpg format at 300 DPI: mkdir -p images & pdftoppm -jpeg -r 300 mypdf.pdf images/pg Therefore, here are my favorite commands: A better way, in my opinion, however, is to use mkdir -p images first to create an "images" directory, then set the output to images/pg so that all output images will be placed cleanly into the images dir you just created, with the file prefix pg in front of each of their numbers. The -jpeg sets the output image format to JPG, -r 300 sets the output image resolution to 300 DPI, and the word output will be the prefix to all pages of images, which will be numbered and placed into your current directory you are working in. Good command-use this instead: # GOOD cmd Then, I remembered there was another tool I use and wrote about, so I googled " linux convert pdf to jpg Gabriel Staples", clicked the first hit, and scrolled down to my answer. I still like pdftoppm, below, much better, however.)
See also my comment here, and my comments under this answer here. 2022: here is the fix for imagemagick so convert will work. I just googled how to convert a PDF to a JPEG today, found this answer, and tried convert, and it doesn't work at all for me:īroken command (doesn't work for me): # BROKEN cmdĬonvert-im6.q16: not authorized `in.pdf' error/constitute.c/ReadImage/412.Ĭonvert-im6.q16: no images defined `out.jpg' error/convert.c/ConvertImageCommand/3258. For the life of me, over the last 5 years, I cannot get imagemagick to work consistently (if at all) for me, and I don't know why people continually recommend it again and again.
