Librarians and archivists use pdfimages (with -png) to extract figures from scientific papers stored in a 32-bit NAS:
for f in *.pdf; do pdfimages -png "$f" "$f%.pdf"; done
Older releases like Debian 9 (Stretch) or Ubuntu 16.04 LTS (Xenial) often shipped with Poppler 0.68.0 in their repositories. To install:
