In the distant past (Before Nop 2014/19, to be precise) we discussed PDF Image Extraction Wizard, which allows you to extract all images fully automatically from a certain page range of a PDF document. A great program for that purpose, but if you only want a handful of scattered images, it’s not the most ideal solution. Then you will benefit more PdfTrick. Drag a PDF file to the window of this program and you can then indicate per page and per image whether you want to save an image. Note: PdfTrick requires Java Runtime Environment.
