I encountered one of those scans which was shared as a single-page PDF. I don’t want it that way, because I want to include it in a web page. I want a simple bitmap image. ImageMagick comes to the rescue:

convert scan.pdf scan.jpg

If the resolution this produces is too low for you, try telling Ghostscript (which ImageMagick uses internally) that you want a different density:

convert -density 300 scan.pdf scan.jpg


Googling linux pdf to jpg produced two useful results:

  1. Batch converting PDF to JPG/JPEG using free software
  2. Converting PDF to PNG/JPG using ImageMagick in Linux
