#### Convert PDFs to JPEGs using the Poppler library and ImageMagick
####
#### This script converts a folder full of PDFs to JPEGs using libpoppler and 
#### ImageMagick. In this case, PDFs are coverted at 150 dpi and outputted as
#### 85 percent quality JPEGs with a maximum width of 800 pixels. Edit these 
#### values to suit your environment.
####
#### To use the script, ensure the script is executable and navigate to a folder
#### of PDFs in the terminal and run: ./pdf2jpg.sh
