To solve the first issue just convert the files to png and after to jpg again, like this example: mogrify -format png *.jpg rm *.jpg mogrify -format jpg *.png rm *.png To solve the second, just execute the following command: sudo sed -i 's/rights="none" pattern="PDF"/rights="read|write" pattern="PDF"/g' /etc/ImageMagick-6/policy.xml Enjoy it!
